ABSTRACT

Background: Hyperpigmentation results in uneven skin tone, with darker skin types disproportionately affected. Objective: Assess efficacy and safety of a novel, hydroquinone (HQ)-free, multimodal pigment-correcting serum (Advanced Brightening Treatment [ABT]) versus 4% HQ in moderate to severe hyperpigmentation, including melasma. Methods: In this split-face study, ABT and 4% HQ were applied topically on randomly assigned facial sides twice daily for 12 weeks. Hyperpigmentation, skin tone evenness, modified Melasma Area and Severity Index (mMASI), Melasma Quality of Life Questionnaire (MelasQoL), self-assessment questionnaires, and tolerability were assessed. Results: Subjects (n = 113; melasma subgroup, n = 44) were Asian (22%), Black/African American (27%), Hispanic (22%), and White/Caucasian (28%). ABT achieved comparable results to 4% HQ. ABT was well tolerated and resulted in improvement versus baseline at all visits in mean overall hyperpigmentation (-11.7% at week 12; P ≤ .001), skin tone evenness (-8.8%, P ≤ .005), and, in the melasma subgroup, mMASI (-50.6%; P ≤ .011) and MelasQoL scores (33.0 vs 46.6 for week 12 vs baseline, respectively; P ≤ .011), with similar results across racial subgroups. ABT was preferred over 4% HQ, with high satisfaction rate (≥89%). Limitations: Quality of life improvements per treatment were not evaluated separately. Conclusion: Efficacy and safety of ABT is comparable to 4% HQ in individuals with facial hyperpigmentation, including melasma, across multiple racial/ethnic backgrounds.

ABSTRACT

BACKGROUND: Facial hyperpigmentation can negatively affect an individual's emotional and psychosocial well-being. AIMS: Assess safety and tolerability of a combination of microdermabrasion (DG) procedures using a novel brightening pro-infusion serum (EC-DG) with a targeted at-home treatment regimen in subjects with mild to severe facial hyperpigmentation, including melasma, post-inflammatory hyperpigmentation, and dark spots. PATIENTS/METHODS: This 12-week, open-label study enrolled 18 subjects (Fitzpatrick skin types I-IV) who underwent 6 in-office DG procedures with EC-DG (one procedure administered biweekly), along with daily topical application of a brightening treatment serum and dark spot cream. End points included change from baseline across multiple skin quality attributes and the Melasma Area and Severity Index (MASI), self-assessment questionnaires, and tolerability assessments. RESULTS: The combination treatment was well tolerated and resulted in significant (p ≤ 0.05) improvements from baseline in radiance, tactile roughness, and moisturization/hydration immediately after the first treatment, in MASI score at day 3, and in overall hyperpigmentation at week 4. Most (94.1%) subjects were satisfied with treatment. CONCLUSIONS: DG procedures using EC-DG combined with a targeted at-home skincare regimen are effective and tolerable for treating facial hyperpigmentation across a broad range of skin types.

ABSTRACT

Purpose: Post-inflammatory hyperpigmentation (PIH) and solar lentigines are dark spots of skin from excessive melanin production due to injury or UV exposure. This 12-week single-center study assessed the efficacy and tolerability of a novel targeted pigment-correcting spot treatment gel suspension cream (Dark Spot Treatment) for improving mild-to-moderate PIH or solar lentigines. Patients and Methods: Female participants (N = 41) aged 25-65 with mild-to-moderate facial dark spots applied Dark Spot Treatment daily for 12 weeks. Investigators assessed overall hyperpigmentation, skin tone evenness, and dark spot intensity, contrast, and size at Weeks 2, 4, 8, and 12. Participant self-assessments occurred at Weeks 1, 2, 4, 8, and 12. Tolerability was assessed by clinical grading and participant reporting. Results: Dark Spot Treatment improved overall hyperpigmentation, skin tone evenness, and dark spot intensity and contrast at Weeks 2 through 12, and dark spot size at Weeks 4 through 12 (all p < 0.001 compared to baseline). Participant self-assessments showed high overall satisfaction. Dark Spot Treatment was well tolerated. Conclusion: The novel pigment-correcting Dark Spot Treatment significantly improved the appearance of PIH and solar lentigines, had high participant satisfaction, and was well tolerated.

ABSTRACT

Purpose: An in-office diamond tip microdermabrasion device (DG) was designed to simultaneously exfoliate, extract, and infuse topical cosmetic serums into the skin to improve its appearance. Combining in-office procedures with take-home skincare may enhance treatment outcomes. This study aimed to assess the efficacy of a novel combination of DG treatments with a take-home cosmetic skincare regimen (DGR) to address facial dryness, hyperpigmentation, photodamage, or acne-prone/oily skin. Patients and Methods: In this 12-week, open-label, single-center study, participants were assigned to 1 of 4 groups according to skin presentation: dry, hyperpigmented, photodamaged, or acne-prone/oily. All participants received 6 bi-weekly DG treatments with tailored DGR topical products. During the DG treatment, the dry, hyperpigmented, photodamaged, and acne-prone/oily groups received hydrating, brightening, antioxidant, and pore-clarifying serums, respectively. Study endpoints included investigator grading, standardized photography, and participant questionnaires. Results: Sixteen participants aged 22 to 70 years with Fitzpatrick Skin Types I-V completed the study. Immediately after the first DG treatment, significant improvements in dryness, radiance, texture, photodamage, and fine lines were achieved (P<0.01). At 72 hours, significant improvements were maintained in all these parameters except fine lines (P<0.05). The DG and DGR combination provided significant long-term improvements at week 12 compared to baseline for dryness, radiance, texture, hyperpigmentation, photodamage, skin tone unevenness, and periocular/perioral fine lines (P<0.05). Conclusion: The combination of DG and DGR showed significant immediate and long-term improvements in skin appearance. These results show that the DG and DGR combination is a well-tolerated and effective intervention to enhance different aspects of facial skin quality.

ABSTRACT

BACKGROUND: Age-related changes in body skin are emerging as important therapeutic targets. A novel topical firming and toning body lotion (FTB) has been developed to target multiple pathways involved in body skin rejuvenation. METHODS: FTB was evaluated in a randomized, double-blind, vehicle-controlled, 12-week study in women (N=54) with mild to moderate lack of firmness on the upper arms and mild to moderate cellulite on the thighs. Investigator clinical assessments, instrumentation evaluations, and patient questionnaires were performed. Histological assessment of ex vivo human skin treated with FTB and gene expression analysis in 3-dimensional human skin models following application of FTB or product comparators were conducted. RESULTS: At week 12, FTB treatment significantly improved (vs baseline) firmness, sagging, smoothness, texture, cellulite, and crepiness on investigator-, instrument-, and photographically assessed outcomes. Participants reported significant improvements in self-perceived efficacy and overall satisfaction with the appearance of their skin following FTB treatment vs vehicle control. Adverse events were mild or moderate in severity. FTB supported new collagen and elastic fiber formation in ex vivo skin. FTB increased skin rejuvenation–associated gene expression vs comparator products. CONCLUSIONS: FTB provided significant improvements in the upper arms and thighs compared with baseline and vehicle control across multiple investigator and instrumentation evaluations. Most participants reported greater efficacy and treatment satisfaction with FTB vs vehicle. FTB treatment stimulated dermal extracellular matrix renewal and induced expression of genes involved in skin rejuvenation pathways. This study provides clinical and preclinical evidence supporting the use of FTB to improve body skin quality. Citation: Makino ET, Jiang LI, Acevedo SF, et al.

ABSTRACT

Purpose: There is growing interest in combining topical treatments with aesthetic procedures to combat signs of aging skin. This study aimed to assess the efficacy and tolerability of a novel cosmetic serum containing 5 different forms of HA (HA5 DG) when used via a proprietary diamond-tip microdermabrasion procedure (DG) to treat skin dryness, fine lines/wrinkles, rough texture, and dullness. Patients and Methods: In this open-label, single-center study, participants received HA5 DG as part of a biweekly DG procedure on the face and neck for 12 weeks. Study participants also applied another take-home HA5 serum to the face twice daily at home, along with a basic skincare regimen. The efficacy of the combined treatment was measured by clinical quantification of multiple skin appearance features, analysis of bioinstrumental measurements, and digital photography. Results: This study enrolled 27 participants, with an average age of 42.7 years and Fitzpatrick skin phototypes I-III (59.3%), IV (18.5%), and V-VI (22.2%), and 23 participants completed the study. The combined treatment had effects in fine lines/wrinkles, skin dryness, smoothness, radiance, firmness, and hydration 15 minutes post-DG. Furthermore, the significant improvements observed in dryness, fine lines/wrinkles, skin smoothness, and radiance were still visible 3 days after and maintained at week 12. Additionally, smoothing of coarse lines/wrinkles, improvement of skin tone evenness, hyperpigmentation, photodamage, and transepidermal water loss were observed at week 12. The treatment had a favorable tolerability profile and was perceived as efficacious and highly satisfactory. Conclusion: This novel combined treatment delivered immediate and prolonged skin hydration and high participant satisfaction, proving it can be an excellent approach for skin rejuvenation.

ABSTRACT

INTRODUCTION: The aging process involves numerous biological mechanisms that have been characterized and proposed as the "hallmarks of aging." Targeting the processes and pathways related to these hallmarks of aging that cause and promote skin aging could provide anti-aging benefits. A novel topical growth factor-based skin care serum (A+) was developed using human fibroblast conditioned media. This study aimed to assess the effects of A+ on four hallmarks of aging and its clinical efficacy in skin rejuvenation in subjects with moderate to severe overall facial photodamage. METHODS: Preclinical studies included immunohistochemistry in human ex vivo skin, and gene expression analysis in human 3D skin models. A 24-week, vehicle placebo-controlled study, including FaceQ patient-reported outcomes and skin biopsy analysis, was performed to assess clinical efficacy and tolerability. RESULTS: Treatment with A+ resulted in reduced expression of cell senescence biomarker H2A.J and upregulation of genes associated with proteasome, autophagy, stemness, and intercellular communication. Clinical assessments showed A+ provided significantly greater reductions in sagging, coarse lines/wrinkles, fine lines/wrinkles, overall photodamage, and overall hyperpigmentation compared with placebo. Subjects felt they appeared younger-looking, reporting a median decrease in self-perceived age of 6 years after 12 weeks of use. Decreased levels of H2A.J and increased expression of key dermal extracellular matrix and epidermal barrier components, including collagen and elastin, were observed in skin biopsy samples. CONCLUSION: The present study shows for the first time the potential effects of a topical growth factor-based cosmeceutical on cellular processes related to four hallmarks of aging (cellular senescence, loss of proteostasis, stem cell exhaustion, and altered intercellular communication) to help delay the aging process and restore aged skin. A+ targets the biological mechanisms underlying the aging process itself and stimulates skin regeneration, resulting in rapid and significant clinical improvements.

ABSTRACT

BACKGROUND: Chronic exposure to air pollution can negatively affect skin health. AIMS: To assess the efficacy of the LUMIVIVE® System (LVS), a skincare system consisting of individual day and night serums, in Chinese women exposed to air pollution. PATIENTS/METHODS: In this single-center, vehicle-controlled study, eligible females (mean age, 49.02 years) were randomized 1:1 to treatment group (LVS plus basic moisturizer) or control group (basic moisturizer). Skin color, sebum content, barrier function, elasticity, and texture were measured at baseline and at each follow-up visit (days 28, 56, and 84). Air pollution parameters were collected throughout the study. RESULTS: Air pollution levels, including PM2.5 and NO2 , were consistently high during the study. The treatment group showed significantly higher skin color L* (p ≤ 0.0001) and lower a* values (p ≤ 0.05) at all follow-up visits compared with the control group, indicating lower skin pigmentation and redness, respectively. Skin color L* and a* values remained unchanged over time for the control group but were significantly different at all follow-up visits compared to baseline (p ≤ 0.0001 and p ≤ 0.05, respectively) for the treatment group. There was an increasing trend for sebum content in the control group, which was not observed in the treatment group. Both groups showed improvements over time in other skin physiology parameters. CONCLUSIONS: The current analysis demonstrates the efficacy of LVS plus basic moisturizer compared with basic moisturizer alone to reduce skin pigmentation and redness, as well as to mitigate sebum production, in Chinese women exposed to air pollution.

ABSTRACT

BACKGROUND: Melasma is an acquired disorder that results in irregular brown patches on the skin that can occur due to hormonal changes. Although pregnancy-induced melasma is usually temporary, it can become a chronic condition, with significant negative impact on quality of life (QoL). AIMS: Determine the efficacy and tolerability of a topical, non-hydroquinone, non-retinol pigment-correcting serum (LYT2) for the treatment of pregnancy-induced melasma. METHODS: This 12-week, single-center clinical trial enrolled 34 non-pregnant women who developed mild to severe facial melasma following a previous pregnancy (mean age, 42 years). LYT2 was applied twice daily to facial skin for 12 weeks in addition to a basic skincare regimen. Outcomes included changes from baseline in skin physiology parameters, such as brightness (L*), using objective digital image analysis, investigator-rated Overall Hyperpigmentation scale, Global Improvement, and Melasma Area and Severity Index (MASI), as well as subject-assessed Melasma Quality of Life Scale. Subjects also completed a questionnaire on self-perceived efficacy and attributes of the study product. Tolerability was assessed by the investigators (erythema, scaling, and edema) and subjects (burning/stinging and itching). Clinical assessments were conducted at baseline and Weeks 4, 8, and 12. RESULTS: LYT2 provided statistically significant reductions in overall hyperpigmentation scores as early as Week 4 (-5.8% change from baseline) and continued through Week 12 (-14.6% change from baseline; all p < 0.001). Significant improvements in MASI scores and QoL were also achieved following LYT2 treatment, which was well tolerated. CONCLUSIONS: LYT2 represents a new efficacious alternative to hydroquinone-based treatments for pregnancy-induced melasma.

ABSTRACT

BACKGROUND: Studies utilizing reflectance confocal microscopy (RCM) and dynamic optical coherence tomography (D-OCT) to assess cosmetic skin changes are limited. METHODS: A 12-week, open-label study was conducted using RCM and D-OCT to evaluate the effects of a topical cosmetic retinol (RET05) on subjects with facial photodamage. Study endpoints included investigator grading, standardized (VISIA-CR) and 3D photography (Antera 3D), independent RCM (VivaScope1500) and D-OCT (VivoSight) image analysis, validated FACE-Q scales, and subject questionnaires. RESULTS: Twenty-three subjects, 45- to 68-year old, with Fitzpatrick skin types II-IV completed the study. After 12 weeks of repeated application, RET05 demonstrated significant corresponding cosmetic improvements for overall photodamage, skin tone unevenness, tactile roughness, fine lines/wrinkles (forehead, periocular, and perioral), and coarse lines/wrinkles (forehead, periocular, and cheeks), and Allergan Skin Roughness Scale. FACE-Q assessments also demonstrated significant improvements from baseline at week 12. RCM analysis showed decreases in all epidermis, less compact stratum corneum (SC), more non-compact SC, decreases in coarse/huddled dermal fibers, and increases in fibrillar dermal fibers, as compared to baseline. D-OCT analysis showed significant decreases in epidermal thickness (ET), reduction of moderate/many collagen fragments and collagen bundles, and significant increases in the stroma attenuation coefficient and collagen density. Moreover, the dermal-epidermal junction was more pronounced, and vascular abundance at 300 and 500 µm depth increased. Independent evaluation of RCM and D-OCT images showed similar decreases in ET and improvements in dermal fibers. CONCLUSION: This study was the first to utilize RCM and D-OCT to evaluate the cosmetic effects of a topical retinoid and further substantiate improvements in skin quality.

ABSTRACT

BACKGROUND: Hyperpigmentation conditions can affect all skin types but occur more frequently in darker skin. Because many factors have been implicated in the etiologies of these disorders, multi-targeted approaches may be required to achieve a better overall outcome in a diverse patient population. AIMS: The purpose of this study was to investigate the safety and efficacy of a combination regimen of a comprehensive cosmetic brightening agent (LYT2) with a broad blend of antioxidants (LVS) to reduce hyperpigmentation and improve overall skin appearance. METHODS: The combination of LYT2 and LVS, in addition to a basic skincare routine, was evaluated in subjects of either Caucasian or Asian (a majority of whom were Indian) descent, presenting with moderate-to-severe hyperpigmentation. Efficacy evaluations consisted of investigator clinical grading of overall hyperpigmentation, skin tone evenness, and radiance, as well as subject self-assessment questionnaires. RESULTS: Immediate and progressive improvement was noted by the investigators for all assessed parameters. At the end of the 12-week study, investigators observed a 45% mean decrease from baseline for overall hyperpigmentation. In addition, a 50% improvement in skin tone evenness and a 58% increase in radiance was observed. These investigator assessments were matched by good patient scores for self-perceived efficacy parameters and high overall satisfaction. One patient (7%) showed a treatment-related adverse event. CONCLUSION: A combination skincare regimen that combines the pigmentation control of LYT2 with the broad antioxidant defense of LVS is a well-tolerated and effective treatment option to improve the appearance of facial hyperpigmentation and make skin more radiant.

ABSTRACT

The neck plays a telling role as an age indicator. Due to its anatomy and function, neck skin ages differently than facial skin and special considerations need to be taken when providing treatment. A randomized, double-blind, regimen-controlled study was conducted to assess the efficacy and tolerability of a novel topical cosmetic cream (NCC) specifically tailored to address the signs of skin aging of the neck and décolletage. Twice daily application of NCC significantly improved skin sagging/laxity of the neck as well as the appearance of fine and coarse lines/wrinkles, crepiness, tactile roughness, overall skin texture, hyperpigmentation, skin tone evenness, and radiance. NCC also significantly improved the appearance of fine and coarse lines/wrinkles, tactile roughness, hyperpigmentation, skin tone evenness, and radiance of the décolletage. Investigator assessments were corroborated by objective cutometer measurements that demonstrated improved skin firmness and elasticity. In vitro analysis in human 3D skin models show that stimulation of neocollagenesis and neoelastogenesis as well as support of cellular proteostasis through proteasome and autophagy activation are potential mechanisms of action for the observed clinical outcomes.

ABSTRACT

Skin activities follow endogenous circadian rhythms resulting in differences between daytime and nighttime properties. To address the variations in skin needs, a novel circadian-based dual serum system (LVS) was developed. A 12-week, double-blind, randomized, regimen-controlled, multi-center study was conducted to assess the efficacy and tolerability of LVS on subjects presenting with moderate-severe photodamage. 61 Female subjects (36–65 years; Fitzpatrick skin types I–VI) completed the study. The active group received LVS (daytime serum and nighttime serum) and basic skin care regimen (moisturizer and SPF 35 sunscreen), while the control group received the basic skin care regimen only. In addition to clinical grading, subject self-assessment questionnaires, and standardized photography, punch biopsies were taken in a subset of subjects for immunohistochemistry. Additionally, swab samples were taken for skin surface oxidation analysis. Significant improvements over control were observed in the active group in Radiance (weeks 4, 8, and 12), Overall Photodamage, Tactile Toughness, and Global Fine Lines/Wrinkles (week 12). Biopsy results, skin swab analysis and standardized photographs support the clinical grading findings. At all follow-up visits, LVS was consistently highly rated over control by subjects, with a significant proportion of subjects agreeing at week 12 that LVS “improved the radiance of my skin,” and “improved the overall health and look of my skin”. Results from this study suggest that LVS may provide essential protective and reparative effects to skin exposed to the damaging effects of environmental factors, and also demonstrates the value of including skin circadian rhythm-based concepts in a topical skincare regimen.

ABSTRACT

INTRODUCTION: Air pollution continues to be a global health concern and recent studies have shown that air pollutants can cause skin damage and skin aging through several pathways that induce oxidative stress, inflammation, apoptosis, and skin barrier dysfunction. Preventive measures need to be considered to retain optimal skin health, and topical skincare products may be able to alleviate the negative effects of air pollution on skin. A randomized, double-blind, placebo-controlled clinical usage study was conducted to assess the efficacy and tolerability of a novel two-part skincare system (LVS) that was developed to provide protection against environmental skin aggressors including air pollution. After 8 weeks of use in subjects exposed to extremely high levels of pollution, LVS provided significant improvements compared to placebo in all clinical efficacy parameters including crow's feet wrinkles, overall skin damage, skin tone evenness, tactile roughness, and visible redness. Subject self-assessment questionnaires showed that the treatment product was highly rated in self-perceived efficacy. Decreased SQOOH and MDA content in skin swab samples suggest that LVS helped to reduce oxidative stress in patients' skin. Histological analyses of biopsy samples using biomarkers related to skin structure, damage and function (collagen IV, MMP1, CPD, and CD1a) further support the clinical benefits of LVS. Altogether, the presented study is among the first to show that topical skincare products can help to reduce pollution-induced skin damage and improve skin quality, especially when specifically formulated with active ingredients that combat the harmful effects of air pollutants.

ABSTRACT

The growing male skincare market reflects the increased interest of men in addressing facial aging concerns and maintaining a healthy youthful appearance. Because of differences in skin structure and aging as well as in lifestyle and behavior, male facial skin presents unique challenges that may result in different priorities or treatment strategies compared to female skin. A clinical study was conducted to assess clinical efficacy and tolerability of a topical skincare treatment product that was developed to address several male facial skin concerns related to skin quality, skin aging, and shaving. The treatment product provided significant improvements in all clinical efficacy parameters including overall photodamage, tactile roughness, fine line/wrinkles, and coarse lines/wrinkles. Furthermore, significant improvements in erythema as well as dryness/scaling were observed. Subject self-assessment questionnaires showed that the treatment product was highly rated in both self-perceived efficacy as well as product attributes. Use of skincare treatment products that tackle specific male facial skin concerns could further optimize skin quality and support healthy and youthful looking skin in men.

ABSTRACT

Skin care products may use various active ingredients to support skin rejuvenation including growth factors and other molecules that help to regenerate extracellular matrix (ECM) and promote skin repair. The biological effect of skin care products with a strong anti-aging claim was assessed in gene expression analyses using an in vitro human skin model. Application of products containing human fibroblast-derived growth factors resulted in signifcant upregulation of genes encoding ECM components including collagens and elastin. Human fibroblasts cultured under hypoxic conditions show increased gene expression of stem cell markers, and their conditioned media could possibly further support skin rejuvenation. Furthermore, a double-blind, randomized, placebo-controlled study was con-ducted in subjects with moderate to severe facial photodamage to assess the cosmetic clinical efficacy of a product containing human fibroblast-derived growth factors. The test product group demonstrated significantly greater reductions in the appearance of fne lines/wrinkles, coarse line/wrinkles, and overall photodamage, compared to the placebo group. Altogether, the results suggest that human fibroblast-derived growth factors support skin rejuvenation by stimulating dermal fibroblasts to generate ECM.

ABSTRACT

Dyschromia is one of the primary complaints for patients with skin of color. Treatments need to achieve a balance between tolerability and efficacy to address existing hyperpigmentation without causing additional damage that could trigger post-inflammatory hyperpigmentation (PIH). An open-label, single-center study was conducted to assess the efficacy of a novel comprehensive pigmentation control serum (LYT2) combined with a series of three very superficial chemical peels (VP) in skin of color subjects. Seventeen female and male subjects aged 36 to 69 years with Fitzpatrick Skin Types III-VI and moderate to severe facial hyperpigmentation were enrolled in the 12-week clinical study. Subjects identified as Asian, Hispanic, African American, or Caucasian ethnicities. Subjects received a series of 3 VP treatments every 4 weeks. LYT2 was applied twice-daily in between VP treatments. Investigator assessments for overall hyperpigmentation, overall photodamage, and skin tone unevenness, as well as standardized digital photography and subject self-assessment questionnaires were conducted at all visits (baseline and weeks 4, 8, and 12). In vivo reflectance confocal microscopy (RCM) of a target lesion was conducted (in a subset of subjects) at baseline and week 12. Fourteen subjects completed the study. The treatment regimen provided statistically significant improvements in all efficacy parameters at weeks 8 and 12 (all P less than equal to 0.03, student's t-test). Standardized digital photography and RCM images support the improvements in overall hyperpigmentation observed by the investigator. At the end of treatment, the regimen was highly rated by subjects with 100% of subjects (strongly agree/agree) that the combination "decreased the appearance of uneven skin tone and discolorations" and "reduced the appearance of sun damage." In addition to this clinical study, independent case studies with this combination treatment regimen at a separate study site were also conducted with results that corroborate the formal clinical study findings. The comprehensive results from these studies suggest that the combination of a comprehensive pigmentation control serum with a series of 3 very superficial chemical peels may provide an effective treatment approach for hyperpigmentation in skin of color patients.

ABSTRACT

Key features of lip aging include loss of volume, color, and definition as well as increases in lines/wrinkles and uneven skin texture. A single-center, open-label clinical study was conducted to assess the efficacy and tolerability of a novel, topical two-step lip treatment (HA5 LS) in female subjects presenting with mild to moderate lip dryness and mild to severe lip condition. Subjects were instructed to apply HA5 LS at least three times a day to ensure coverage 8 hours a day for four weeks. Clinical assessments for efficacy and tolerability were conducted at baseline, baseline post-application, week 2, and week 4. Standardized digital photography, subject self-assessment questionnaires, and instrumentation measurements for skin hydration (corneometer) and lip plumpness (digital caliper) were also conducted. Thirty-six female subjects aged 22-40 years enrolled in the study. HA5 LS provided instant and long term effects, achieving significant improvements in all clinical grading parameters including lip texture, color, definition/contour, scaling, cupping, lines/wrinkles, lip plumpness, and overall lip condition from baseline post-application to week 4 (all P less than equal to .001; Wilcoxon signed-rank test). Instrumentation measurements for hydration and digital caliper at weeks 2 and 4 were also significant (all P less than equal to .032; paired t-test). HA5 LS was also well-tolerated and highly-rated by subjects throughout the study duration. Results from this study suggest that HA5 LS addresses the key features of lip aging, providing both instant and long-term benefits.

ABSTRACT

BACKGROUND: Neuromodulator injection procedures are an effective treatment for moderate-to-severe facial wrinkles, but do not address the superficial fine lines and wrinkles caused by age-related loss of intrinsic hyaluronic acid levels in the epidermis. OBJECTIVE: In this study, the authors assess overall facial skin quality and patient satisfaction when combining topical treatment with the a topical cosmetic serum (HA5) and applying to the entire face following a pre-elected neuromodulator injection treatment to the lateral canthal areas. METHODS AND MATERIALS: Twenty female subjects aged 36 to 63 years with moderate-to-severe under-the-eye fine lines and/or wrinkles enrolled in the study. HA5 was applied the entire face at baseline immediately post-injection and twice daily for eight weeks. Clinical assessments were conducted at baseline; 15 minutes post-procedure; and at Weeks 2, 4, and 8. RESULTS: Statistically significant improvements were observed immediately post-procedure and after eight weeks, along with high patient satisfaction. CONCLUSION: The combination of topical serum and injectable procedure provided a rapid onset of improvements in fine lines/wrinkles appearance and skin texture and long-term overall improvements in areas not treated by the injection. These results support how this novel combination can provide physicians with a comprehensive approach to optimize patient outcomes.

ABSTRACT

Skin aging is a combination of multifactorial mechanisms that are not fully understood. Intrinsic and extrinsic factors modulate skin aging, activating distinctive processes that share similar molecular pathways. One of the main characteristics of youthful skin is its large capacity to retain water, and this decreases significantly as we age. A key molecule involved in maintaining skin hydration is hyaluronic acid (HA). Concentration of HA in the skin is determined by the complex balance between its synthesis, deposition, association with cellular structures, and degradation. HA bio-equivalency and bio-compatibility have been fundamental in keeping this macromolecule as the favorite of the skincare industry for decades. Scientific evidence now shows that topically applied HA is unable to penetrate the skin and is rapidly degraded on the skin surface. SkinMedica's HA5 Rejuvenating Hydrator (SkinMedica Inc., an Allergan company, Irvine, CA) promotes restoration of endogenous epidermal HA homeostasis and provides instant smoothing and hydration of the skin. These dual benefits are accomplished through the combination of 2 breakthrough technologies: 1) a unique blend of actives powered by SkinMedica proprietary flower-derived stem cell extract that restores the endogenous production of HA; and 2) a proprietary mix of 5 HA forms that plump the skin, decreasing the appearance of fine lines/wrinkles. Pre-clinical studies demonstrated that HA5 induces expression of key epidermal differentiation and barrier markers as well as epidermal HA synthases. A decrease expression of hyaluronidases was also observed upon HA5 application. Initial clinical studies showed that within 15 minutes of application, HA5 instantly improves the appearance of fine lines/wrinkles and skin hydration. Subjects that continue using HA5 (for 8 weeks) demonstrated significant improvements in fine lines/wrinkles, tactile roughness, and skin hydration. In summary, the blend of these 2 key technologies present in HA5 promotes restoration of endogenous epidermal HA while delivering instant smoothing effects.
