RESUMO

BACKGROUND: Blue wheals and blue angioedema, the adverse reactions to blue dye injections with or without anaphylaxis, are poorly defined. OBJECTIVE: The objective is to review the characteristics (ie, sex and age at onset, interval between blue dye injection and symptom onset, clinical manifestations, duration of blue wheals or angioedema), natural courses, and treatments of blue dye adverse reactions. METHODS: A review of the articles published through July 2021 was performed per the Preferred Reporting Items for Systematic Reviews and Meta-Analysis recommendations. RESULTS: Across 523 patients (175 studies) with any adverse reactions to blue dye injections, wheals, angioedema, or both occurred in 193 patients (36.9%). Of these 193 patients, 68 patients (35.2%) developed blue wheals or angioedema, 118 (61.1%) had ordinary wheals or angioedema (nonbluish), and 7 had both (3.6%). We reviewed 169 patients with available data (99 with ordinary lesions and 70 with blue lesions). Patent blue violet had the highest rate of inducing blue wheals or angioedema (odds ratio 4.9). Almost half of the patients with blue wheals or angioedema developed systemic symptoms; and of those with systemic symptoms, all except 1 progressed to anaphylaxis. On-demand treatments with antihistamines, corticosteroids, and epinephrine were commonly used and effective. CONCLUSIONS: Using blue dyes can lead to blue wheals or angioedema and systemic reactions. In patients with a history of a severe allergic reaction to a blue dye, repeat administration of a blue dye should be used only after carefully weighing all the risks and benefits.

RESUMO

Autologous cultured fibroblast injections for soft tissue augmentation are a potential alternative to other filler materials. No studies have compared autologous fibroblast injections and hyaluronic acid (HA) fillers for treating nasolabial folds (NLFs). To compare the efficacies and safeties of autologous cultured fibroblast injections and HA fillers for treating NLFs. This prospective, evaluator-blinded, pilot study enrolled 60 Thai female adult patients diagnosed with moderate to severe NLFs. They were randomized to receive either 3 treatments of autologous fibroblasts at 2-week intervals or 1 treatment with HA fillers. The primary outcome was the clinical improvement of the NLFs graded by 2 blinded dermatologists immediately after injection and at 1-, 3-, 6-, and 12-month follow-ups. Objective measurement of the NLF volume was evaluated. Patient self-assessment scores, pain scores, and adverse reactions were recorded. Of the 60 patients, 55 (91.7%) completed the study protocol. The NLF volumes improved significantly in the autologous fibroblast group at all follow-ups relative to baseline (P = 0.000, 0.004, 0.000, 0.000, and 0.003). The patients in the autologous fibroblast group rated more noticeable NLF improvements than those in the HA filler group (3-month follow-up, 58.41% vs. 54.67%; 6-month follow-up, 52.50% vs. 46%; 12-month follow-up, 44.55% vs. 31.33%). No serious adverse reactions were recorded. Autologous fibroblast injections are safe and effective for treating NLFs. These injections also promise sustained growth of living cells, possibly leading to a greater persistence than shown by other fillers.

RESUMO

Background: Submental fat is a noticeable fat in the submental region that is of great concern aesthetically, especially to female patients. A 1060-nm diode laser is a clinically proven device for the laser lipolysis of subcutaneous fat cells. This study aimed to evaluate the safety and efficacy of a 1060-nm diode laser for submental fat reduction. Methods: Twenty subjects with unwanted localized submental fat were treated with a single session of a 1060-nm diode laser with an energy setting between 0.95 and 1.40 W/cm2, depending on each patient's tolerance. Submental fat thickness measurements were documented at baseline, and 1, 3, and 6 months after treatment. Clinical photographs, ultrasound images, and adverse events were evaluated at each follow-up visit. Subjects responded to a satisfaction questionnaire at the end of the study. Results: The subjects had a mean age of 34.55 ± 6.19 years, a mean body weight of 70.66 ± 10.55 kilograms, and most (95%) were women. The average energy setting was 0.95-1.40 W/cm2, with a pain score of 3.90 ± 1.30 on a 0-to-10 scale. A significant reduction in submental fat thickness measured by ultrasound was noted at post-treatment month 3 (falling to 0.46 ± 0.13; P = 0.013). However, there was a slight increase in the submental fat thickness at the 6-month follow-up (to 0.48 ± 0.12); the change in the thickness relative to the baseline was nonsignificant (P = 0.121). Most subjects reported an improvement 6 months after the treatment. No severe adverse events were observed throughout the study period. Conclusion: Our study demonstrated the potential role of 1060-nm Diode laser for the treatment of localized submental subcutaneous adiposities. It is a promising alternative treatment modality for patients seeking an in-office, nonsurgical procedure for fat reduction without severe complications.

RESUMO

INTRODUCTION: Monopolar radiofrequency (MRF) is a valuable modality for tightening and contouring mild-to-moderate facial skin laxity. Few studies have evaluated new-generation MRF devices for lower facial laxity in Asians. This study aims to evaluate the efficacy and safety of MRF for treating lower facial laxity in Asians. METHODS: This prospective cohort study enrolled 30 volunteers with Fitzpatrick Skin Types III-V and mild-to-moderate skin laxity. Subjects received a single MRF treatment. Self-assessments and adverse events were recorded. Two blinded dermatologists graded improvements (6-point scale) after treatment and 1, 3, and 6 months later. RESULTS: All subjects completed the study. Treatment energy levels ranged from 2 to 4. The average number of shots was 412 ± 49, delivered in 3-4 passes with 15-30% overlap. All patients reported improvement in lower facial laxity immediately after treatment. Most patients had mild-to-moderate improvement over the 6-month follow-up. Continuous improvement was observed at the 1-, 3-, and 6-month follow-ups (P < 0.01). Significant improvement was seen at the 6-month follow-up compared with the 1-month follow-up (P < 0.01). Subjects tolerated the procedure well: the average pain score was 3.13 out of 10, and no serious adverse events were observed. CONCLUSIONS: The new-generation MRF device we tested was effective and safe for mild-to-moderate lower facial laxity in Asian skin. The latest MRF technology offers improved safety to prevent complications. Appropriate patient selection, setting, and protocols are mandatory to achieve optimal clinical outcomes. THE TRIAL REGISTRATION NUMBER: TCTR20210326002.

RESUMO

BACKGROUND: Cryotherapy is typically performed by physicians. No cost-utility studies of home-based cryotherapy have been reported. OBJECTIVES: To study the cost utility of home-based cryotherapy devices and in-hospital liquid nitrogen therapy for cutaneous warts. MATERIALS AND METHODS: This randomized, controlled, investigator-blinded trial was carried out on patients with cutaneous warts. Participants were randomly assigned to two groups: home-based cryotherapy and in-hospital liquid nitrogen therapy. Clinical examinations were conducted at baseline and monthly until cure, and outcomes (cure rate, side effects, total costs, and quality of life) were compared. A cost-utility analysis was performed. RESULTS: Nineteen of 22 patients completed the treatment and were analyzed. The efficacy of home-based cryotherapy and in-hospital therapy was 72.8% and 64.3%, respectively. Side effects (pain, redness, and burning) were observed. The mean numbers of medical visits were 2.83 for home-based therapy and 3.30 for in-hospital therapy. The total costs for home-based therapy and the in-hospital therapy were US $76.03 and $100.45, respectively. The home-based therapy had 0.2297 quality-adjusted life years, slightly higher than the corresponding value of 0.2254 for in-hospital therapy. CONCLUSIONS: Home-based cryotherapy devices are a cost-saving strategy with similar efficacy to in-hospital liquid nitrogen therapy.

RESUMO

INTRODUCTION: Laser lipolysis is a rapidly growing noninvasive body-contouring treatment in Asians. There is increasing demand for leg contouring, especially in areas where unwanted fat deposits are prominent despite diet and exercise. Medial fat knees are one of the esthetic concerns of women today and can be a challenging problem in terms of treatment. There are few noninvasive options to remove fat from these areas. This study aims to evaluate the safety and efficacy of a 1060-nm diode laser for medial knee fat reduction. METHODS: Nineteen subjects with localized unwanted fat on the medial knees were enrolled into this study. All of them were treated with a single session of 1060-nm diode laser at a power setting of 1.0-1.4 W/cm2, depending on patient tolerance. Body weight, knee circumference at 3 cm above the medial epicondyle of the femur, and knee fat thickness measured by ultrasonography were recorded at baseline and 1, 3, and 6 months after treatment. Clinical photographs and ultrasound images were taken before and after treatment. Side effects were documented during follow-up visits. Subjects answered a satisfaction questionnaire at the completion of the study. RESULTS: All subjects were female, with mean age of 32.3 ± 5.3 years and body weight of 59.8 ± 11.6 kg. The average power setting was 1.3 ± 0.1 W/cm2 with pain score of 6.1 ± 1.0. Significant reduction in knee circumferences (p < 0.001) at 1-, 3-, and 6-month follow-up visits compared with baseline, and knee fat thickness measured by ultrasound in both axial and sagittal plane at 1 and 6 months after treatment (p = 0.036 and p < 0.001, respectively) were recorded. Side effects were mild and transient, including mild erythema and tenderness. CONCLUSION: The 1060-nm diode laser is effective and safe for knee circumference and medial knee fat layer thickness reduction. TRIAL REGISTRATION: ClinicalTrials.gov identifier, TCTR20220219002.

RESUMO

Hyperpigmentation of split-thickness skin grafts (STSGs) is commonly found among Asians, and it is also challenging to treat. Although the 1064-nm Q-switched Nd:YAG laser has been used as a standard treatment for skin hyperpigmented lesions, there are limited number of reports focusing on the treatment of hyperpigmentation of STSGs. We aimed to evaluate the efficacy of 1064-nm Q-switched Nd:YAG laser for treatment of hyperpigmented STSGs. Half of each STSGs was treated with the 1064-nm Q-switched Nd:YAG laser, while the remaining was left untreated as comparison. The laser was applied for 4 times with 2-4-week interval. The treatment outcomes were compared by measurement of melanin index, erythema index, and photographs of STSGs at prior to enrollment, before each treatment session, and after 1 month of treatment completion. Five patients with 11 skin graft lesions were enrolled. The melanin index was significantly improved after the 2nd session and after treatment completion in laser-treated area (p = 0.006 and p = 0.001, respectively). There was non-significant difference in erythema index. The photographic comparison showed brightened of laser-treated area after treatment completion and improved skin texture. The 1064-nm Q-switched Nd:YAG laser can significantly reduce melanin index of STSGs and can be an alternative treatment for hyperpigmentation of STSGs.

RESUMO

Talaromyces (formerly Penicillium) marneffei is a dimorphic fungus that causes talaromycosis (formerly penicilliosis). The condition is predominantly found in patients with HIV. Important diagnostic clues are a history of living or travelling in endemic areas, and central umbilicated skin lesions. Dermoscopy is particularly useful for providing rapid bedside information, with a round, whitish, amorphous structure being the most common finding. Immune reconstitution inflammatory syndrome (IRIS) may occur. Driven by the initiation of antiretroviral therapy, IRIS is an exaggerated response of T cells to pathogens. Although mycobacterial and cryptococcal opportunistic infections are common with IRIS, a linkage between T. marneffei and IRIS has rarely been reported. Here, we report on a literature review of patients with HIV who developed IRIS associated with talaromycosis. Dermatologists should be aware of the cutaneous and dermoscopic findings of talaromycosis as they provide important clues that enable its early diagnosis and treatment.

RESUMO

BACKGROUND: Pitted keratolysis (PK) is a superficial bacterial infection diagnosed mainly by clinical manifestations. Current data on its dermoscopic and histopathological findings, and the correlation of those findings, are limited. OBJECTIVES: To evaluate the clinical manifestations, dermoscopic, and histopathological findings of PK and to determine the correlations. METHODS: Forty naval cadets with PK and five cadets with normal feet were enrolled this cohort study and provided informed consent. Dermoscopy was independently applied and evaluated by 2 dermatologists. Shave biopsies were performed on 37 patients with PK. RESULTS: Pits were the most common dermoscopic finding (88.1%). The dermoscope had more sensitivity for the detection of PK than the naked eye examinations. Apart from the pits and the presence of bacteria, the most common histopathological finding for PK was color alteration of keratin. The presence of bacteria correlated with interrupted dermatoglyphic lines and the color alteration of keratin. Moreover, the presence of bacteria at the base of pits was related to worse treatment outcomes. CONCLUSIONS: Dermoscopy is a useful tool for PK diagnosis. Color alteration of keratin is another histopathological finding for PK. The presence of bacteria is associated with worse treatment outcomes.

RESUMO

BACKGROUND: Surgical and nonsurgical methods are used for treating basal cell carcinoma (BCC). Few randomized controlled trials exist on the effectiveness of the pulsed dye laser (PDL) on BCC treatment. OBJECTIVE: We investigated the effectiveness of PDL treatment in a single session for the management of nodular and superficial BCCs on the trunk and extremities of adults using a randomized, double-blind, controlled technique. METHODS: We used settings of fluence 7.5 J/cm2, 3-ms pulse duration, no dynamic cooling, 10-mm spot size, 10% overlap between pulses, and 2 stacked pulses on a 595-nm wavelength laser. Histopathologic clearance on excision of tumor with 4-mm margins was the primary outcome measure. RESULTS: Twenty-four patients were included in the study, with 14 in the laser treatment group and 10 patients in the sham/control group. In total, 10/14 (71.4%) of the tumors in the treatment group were successfully treated with no residual tumor on excisional specimen histology, compared with 3/10 (30.0%) of the control group (p = .045). CONCLUSION: Our study shows that PDL may be an effective treatment for low-risk BCCs of the trunk and extremities, but the cure rate is lower than those of other treatments for BCC. Thus, PDL under the current settings cannot be recommended.

RESUMO

Intradermal injection of botulinumtoxinA (BoNT/A) has been used off-label by many clinicians for the purpose of face-lifting effect. Some studies on AbobotulinumtoxinA (AboA) demonstrated clinical efficacy on face-lifting effect when comparing to normal saline solution (NSS). So far, there is no split-face comparison study on face-lifting effect of IncobotulinumtoxinA (IncoA). The objective of this study was to compare the face-lifting effect of IncoA intradermal injection and NSS. Twenty-two subjects were enrolled and randomly injected with IncoA at 1:6 cc dilution (100 unit or 1 vial in 6 cc of NSS) on one side, and NSS on the other side by using intradermal injection technique. Standardized photographic documentation with 2-, and 3-dimentional imaging system (Vectra H1, Canfield Scientific, Inc., Fairfield, NJ) were obtained at baseline, and at 2 weeks after treatment. The face-lifting effect was graded by the subjects and two blinded dermatologists, using photographic comparison. Side effects were also recorded at the end of the study. Immediate face-lifting was identified on the side that was treated with IncoA by blinded injectors in 63.6% of patients. Of all subjects, 17 (77.3%) have noticed the improvement of skin laxity on the side that was treated with IncoA at 2 weeks after treatment. The difference in facial contouring volume measured by Vectra H1 imaging system on IncoA side was significantly higher (P = .033) when comparing to NSS side in patients aged <36 years old. However, there was no statistically significant difference in face-lifting when comparing between IncoA and NSS evaluated by two blinded dermatologists (P = 1.00). Facial asymmetry was found in 36.4% of subjects. This study demonstrated the face-lifting effect of IncoA intradermal injection. Further studies with larger number of subjects and proper method of evaluation should be done to verify these findings.

RESUMO

INTRODUCTION: Intradermal injection of botulinum toxin type A (BoNT/A) has been used off-label by many clinicians for face-lifting. Previous studies on abobotulinumtoxinA (ABO) (Dysport®; Ipsen Biopharm Ltd.) have demonstrated clinical efficacy in face-lifting when compared to normal saline solution (NSS). However, few clinical studies have evaluated ABO in terms of duration of sustained effects for face-lifting. METHODS: Thirty subjects were enrolled, and their face was injected with ABO at a dilution of 1 vial:7 mL (500 U in 7 mL of NSS) using an intradermal injection technique. Standardized photographic documentation was obtained using a two-, and three-dimensional imaging system (Vectra H1, Canfield Scientific, Inc, Fairfield, NJ) at baseline, immediately after injection, 2 weeks after injection and at 1 , 2 , 3 , 4 , 5 and 6 months of follow-up after treatment. The face-lifting effects were graded by both the subjects and two blinded dermatologists who compared photographs taken at the different time points. Side effects were also recorded at the end of the study. RESULTS: Of the 30 subjects, 28 completed treatment and attended every follow-up visit. All subjects were female with Fitzpatrick skin type II to IV. The average age of the subjects was 27.6 ± 3.4 (range 22-34) years. The total number of ABO units used varied for each subject (range 200-250 U), with the average (± standard deviation) dose being 237 ± 19 units. Most of the subjects reported significant face-lifting up to 3 months post-procedure. However, face-lifting assessed by blinded dermatologists was notably lower than that of each patient's evaluation. The difference in the facial contouring volume of the nasolabial fold and jawline, as measured by the Vectra H1 imaging system, was statistically significant from baseline up until 3 months after injection (p = 0.001 and p = 0.001, respectively). The only side effect found in this study was minimal bruising, which was seen in 13.8% of subjects. None of the subjects reported facial asymmetry, either at rest or during facial expression. CONCLUSION: The results of this study demonstrate the face-lifting effect of ABO intradermal injection. The results show sustained effects up to 3 months after injection.

RESUMO

This split-face, double-blind, randomized controlled study examines the efficacy of fractional thulium laser (FTL)-assisted delivery of topical tranexamic acid (TXA) compared with FTL alone as a treatment option for melasma. Forty-six adults with Fitzpatrick skin types III-V and recalcitrant melasma underwent four weekly treatments with fractional 1927-nm thulium laser on both sides of the face. Immediately after treatment, TXA was applied to one side of the face and normal saline solution (NSS) to the contralateral side as control under occlusion. Melanin index (MI), modified MASI (mMASI), and patients' self-assessed improvement scores were measured at baseline, 1 week, 4 weeks, and 3- and 6 months after the final treatment and were examined statistically with a paired sample t test with significance set at p ≤ 0.05. The majority of the participants (95.7%, n = 44) were female with Fitzpatrick skin type IV (82.6%) and a mean age of 48.0 ± 10.0 years. Twenty-nine individuals were able to be followed up until the 6-month assessment. Significant improvement from baseline was seen in both the MI and mMASI scores for both the TXA and control sides at 3 months, with no statistically significant difference between sides. By the 6th month, significant differences in MI and mMASI scores from baseline were still noted, except in the MI for controls. The patients' self-assessment showed similar patterns. No serious adverse events were reported for either group. A regimen of FTL-assisted delivery of TXA over a 4-week period is a safe and effective treatment option for melasma, producing significant improvement up to 3 months. Results further would suggest a repeat regimen every 3 months could be useful for treatment of recalcitrant melasma.

RESUMO

BACKGROUND: Recently, macro-focused ultrasound (MFU) has become a popular noninvasive esthetic treatment for facial laxity. However, there are no studies done that evaluated the use of MFU with a 2.0 mm transducer for upper facial lifting. AIMS: To evaluate the efficacy and safety of MFU with a 2.0 mm transducer in the treatment of upper facial laxity in Thai patients. METHODS: This was a prospective, evaluator-blinded pilot study with 34 Thai patients diagnosed with mild to moderate facial laxity. Patients were treated with a single session of MFU with 2.0 mm transducer at the forehead, lateral and just below the eye area. Primary outcome was the clinical improvement of upper facial laxity graded by 2 blinded dermatologists at baseline, 1-week, 1-, 3-, and 6-month follow-up. Objective measurements including eyebrow height, upper facial volume, and textural irregularities were evaluated. Patients' self-assessment scores and adverse effects were also recorded. RESULTS: Out of 34 patients, 27 (79.4%) attended all follow-ups. Clinical improvement of upper facial laxity was observed as early as 1-week follow-up. Eyebrow height elevation was significantly increased at every follow-up (P = .000) with an average of 1.22 mm at 6-month follow-up. Wrinkles improved significantly at 1-week and 6-month follow-up (P = .002 and P = .010, respectively). Skin roughness showed significant improvement at 6-month follow-up (P = .004). Majority of the patients (53.6%) reported marked improvement at 3-month follow-up. No serious adverse event was noted. CONCLUSION: Macro-focused ultrasound is a safe and effective treatment for upper facial laxity and skin textural irregularities in patients with mild to moderate degree of laxity.

RESUMO

BACKGROUND: Postacne erythema (PAE) is a common sequela of inflammatory acne vulgaris, treatment of which has been challenging due to limited options available and the variability of results for each modality. Recently, a 577-nm high-power optically pumped semiconductor laser (HOPSL) initially developed for vascular lesions has shown promising results for the treatment of PAE. AIMS: To evaluate the efficacy and safety of 577-nm HOPSL in the treatment of postacne erythema. METHODS: This was a split-face, randomized controlled trial pilot study. Twenty-one patients with PAE on both sides of their face were enrolled. Each subject's face sides were randomly assigned to either receive 577-nm HOPSL treatment (QuadroStar PRO™, Asclepion Laser Technologies) using the scanner handpiece, 1mm spot size, 80% coverage, 12-15 J/cm2 , 30 ms, 2 passes for 3 sessions at 1-month intervals, or no treatment at all. Outcome measures such as overall improvement, the Erythema Index (EI), and Melanin Index (MI) from 3 different areas on both treatment and control sides were assessed at baseline, and 1-month follow-up after each treatment session. Side effects including pain, erythema, swelling, and crusting were also recorded. RESULTS: Upon completion of the treatment period, the mean EI was significantly decreased in both treated and nontreated sides of the face (P < .001 and P = .001, respectively). The laser-treated sides already demonstrated significant reduction in the mean EI compared with nontreated sides at 1 month after the 2nd treatment (P = .007). The mean MI of both sides, however, did not show any statistically significant differences from baseline, and likewise when comparing between sides. Patients reported more improvement on laser-treated sides compared with nontreated sides. Reported side effects were limited to mild discomfort during treatment and transient facial erythema lasting approximately 30 minutes. CONCLUSION: Patients who received treatment with the 577-nm HOPSL had better outcomes with minimal side effects at 1 month after 2 treatments as compared to those who did not receive any treatment. Therefore, the 577-nm HOPSL may be considered as an effective adjuvant treatment for PAE and early erythematous atrophic scars.

RESUMO

BACKGROUND: Multiple treatment modalities have been developed to treat atrophic acne scars with varying degrees of success. Post-inflammatory hyperpigmentation (PIH) after acne scar treatments remain a major concern in Asian patients. Fractional radiofrequency (FRF) has been used in many dermatological skin conditions including acne scars. AIMS: To determine the efficacy and safety of FRF nanoneedle system in the treatment of acne scars in Asians. METHODS: This is a prospective, evaluator-blinded study with 25 subjects diagnosed with moderate to severe acne scarring. All subjects received 3 monthly treatments of the FRF nanoneedle system on both cheeks. Primary outcome was the clinical improvement of acne scars graded by 2 blinded dermatologists at baseline, 1-, 3-, and 6-month follow-ups. Objective scar volume analysis was done using ultraviolet A (UVA) light video camera. Subjects' self-assessment, pain score, and adverse events were also recorded. RESULTS: Twenty-three out of 25 subjects completed the study and attended all follow-up. Clinical improvement of acne scars was observed as early as 1-month follow-up. Objective evaluation of acne scar volume decreased significantly on all follow-up compared to baseline (P < .005). Majority of the subjects (48%) reported marked improvement in their acne scars. Adverse events such as pain, erythema, burning sensation, edema, scab formation, and PIH were mild and temporary. CONCLUSIONS: FRF nanoneedle system is a safe and effective treatment for acne scars in Asians. However, despite the significant changes in the scar volume, caution should be used to avoid excessive coagulation resulting in PIH.

RESUMO

BACKGROUND: Olive leaf extract (OLE), a naturally extracted product from olive leaves, contains oleuropein and other bioactive phenolic compounds. Oleuropein was identified to have various medical properties. It was also found to inhibit the effects of both acute and chronic UVB-induced skin damage as well as accelerate wound healing activity. AIMS: To evaluate the efficacy of olive leaf extract-containing cream on facial rejuvenation. METHODS: This is a prospective pilot study with a total of 36 participants, who presented with photoaging skin. All participants applied the olive leaf extract-containing cream (SUPERHEAL™ O-Live Cream, PhytoCeuticals, Inc, USA) to their whole face twice daily for 2 months. Primary outcomes measured in the study were the changes in the biophysical properties of the skin assessed with the following parameters: melanin and erythema index, transepidermal water loss (TEWL), skin hydration, skin pH, sebum level, texture, and wrinkles. RESULTS: After 2 months, TEWL decreased significantly (P = .007) and maintained the results 1 month after discontinuation of the treatment (P = .007). Skin hydration also increased significantly after 2 months (P = .004). Wrinkles improved significantly on all follow-ups (P < .001, P = .001, P = .001, respectively). An image of the skin captured using Visioscan® showed improvement of the skin texture 2 months after treatment. Majority of the participants (64%) noted improvement in their skin texture. CONCLUSION: Olive leaf extract-containing cream provided benefits on skin rejuvenation in human skin.
