Effectiveness and safety of nonablative fractional laser and infrared bipolar radiofrequency for treating periorbital wrinkles.

Non-ablative fractional laser (NAFL) and radiofrequency (RF) are popular for treating periorbital wrinkles owing to short downtime and low risk of side effects. To compare the effectiveness and safety of infrared bipolar radiofrequency (IR-RF) and NAFL, including 1540 nm Er: glass and 1927 nm thulium-doped laser, to determine the better option for clinical treatment of periorbital wrinkles. Twenty-seven patients assigned to 3 groups underwent split-face treatment. Two of the three treatments were randomly selected for patients in each group: IR-RF, 1540 nm Er: glass NAFL, and 1927 nm thulium-doped NAFL. Therapeutic outcomes were subjectively and objectively evaluated six months after the last treatment. Side effects and pain evaluations were conducted. Fitzpatrick wrinkle scores revealed no statistical difference for IR-RF, whereas the NAFL-treated sides exhibited significant improvements (p < .05). VISIA analysis of skin texture showed similar results. In IR-RF-treated sides, patients over 50 years old exhibited significant improvements compared with those below 50 (p < .05). The sample size was small. More objective evaluations like photometer measurements are required. NAFL is effective and safe for improving periorbital wrinkles, but IR-RF might be more suitable for elderly patients, particularly those with low pain tolerance.

Safety and efficacy evaluation of botulinum toxin an injection by FITTER® microneedle to treat medial lower eyelid wrinkles.

BACKGROUND: Treatment for medial lower eyelid wrinkles is in great demand now. However, conventional injection of botulinum toxin A (BTX-A) often leads to serious complications. AIMS: We aim to evaluate the safety and efficacy of BTX-A injection with microneedle to treat medial lower eyelid wrinkles. METHODS: We collected clinical data of 16 patients to treat dynamic wrinkles on the medial aspect of the lower eyelid. Adverse effects at each stage of the treatment were recorded. We used VISIA to compare the static and dynamic wrinkles of the medial lower eyelid before and after treatment. Furthermore, patients and physicians evaluated the wrinkles with Kappa scores. RESULTS: All 16 patients completed the study. The objective evaluation indicator (the Ra variable given by VISIA) progressively and significantly decreased at 1 month and 3 months after treatment. The kappa scores given by patients and by surgeons were both significantly reduced after treatment. No adverse reactions, such as pouch prolapse, diplopia, and canthal tendon laxity, occurred at 1 week, 1 month, or 3 months after the treatment. CONCLUSION: BTX-A treatment of medial lower eyelid wrinkles with microneedle injection allows better control of the injection depth and reduces both the amount of BTX-A needed and the incidence of complications while maintaining the natural dynamic expression.

Periorbital Skin Rejuvenation of Asian Skin Using Microneedle Fractional Radiofrequency.

BACKGROUND: The periorbital area plays an important role cosmetically. Periorbital wrinkles are attributed to long-term, repeated use of orbicularis oris muscles and UV-induced dermal collagen degeneration. Fractional microneedle radiofrequency (RF) treats scars and laxity by creating vertical channels of injury in the dermis, triggering a scarless healing cascade and neocollagenesis. OBJECTIVE: To evaluate the effect and safety of a novel fractional microneedle RF device on periorbital wrinkles based on several objective indicators. METHODS: Eleven healthy Korean patients aged 30 to 75 years with periorbital wrinkles were included in this study. Wrinkle grades were evaluated using the Fitzpatrick wrinkle assessment scale (WAS). The melanin and erythema index, transepidermal water loss (TEWL), and three parameters for elasticity were recorded. Skin biopsies were obtained in patients who consented. RESULTS: All patients exhibited wrinkle improvement in the lateral periorbital area, and two patients also showed efficacy in the lower eyelid area. There was a statistically significant decrease in WAS and a significant improvement in the melanin index of V4 and V5. TEWL also showed a considerable decline on V4 and V5, suggesting that the water content of the skin increased with repeated laser sessions. A peak increase in viscoelasticity and a decrease in retraction time following the first laser application were observed. In the histopathologic examination, the dermis had a denser collagen and elastin content. CONCLUSION: Microneedle fractional RF resulted in statistically significant long-term clinical improvement of periorbital wrinkles and enhanced pigmentation and skin hydration.

Objective, measurable assessment of the elasticity of the skin around the eyes following the carboxytherapy treatment.

BACKGROUND: Carboxytherapy is one of the most popular procedures used in dermatology. The treatments are known to be minimally invasive and highly effective for various skin disorders. Therefore, the research carried out in the paper is purposeful and addresses an important area of aesthetic therapies. AIMS: Objective, apparatus-based assessment of the effect of carboxytherapy on skin elasticity around the eyes. PATIENTS/METHODS: The study included a group of 39 Caucasian individuals aged 35-55 years. Participants were subjected to a series of five carboxytherapy treatments of eye area at weekly intervals. The Cutometer measuring probe was used to assess skin elasticity. Additionally, photographic documentation was out using the Fotomedicus system. RESULTS: In this study, statistically significant increase in R2 parameter was found as the result of applied treatment. This parameter is considered to be the most important indicator of changes in skin elasticity. In 29 out of 39 subjects, the carboxytherapy treatment significantly improved skin tension and elasticity. Such therapy may also exert a beneficial effect on flexibility since in 28 participants the favorable change in the R7 parameter was visible. CONCLUSIONS: The objective analysis of the impact of carboxytherapy treatment on parameters determining skin elasticity revealed that this therapy can be used as an anti-aging method in the eye area. Obtained results are in agreement with other biochemical, histological, and photographical documentation analyses of the effect of carboxytherapy on skin, performed by independent researchers.

Periorbital Rejuvenation: A Study on the Use of Dermal Threads as Monotherapy, with a Review of Literature.

The periorbital region, a major impressionable area holds a special place in aging of the face. It reflects chronological aging which are reflected not only as structural changes but also emotive expressions of sadness and tiredness. Dermal threads have been used in combination with other aesthetic procedures, however their use as monotherapy especially in periorbital region needs evaluation. Aim: To evaluate the improvement in wrinkling and skin texture in the infero-lateral periorbital region with monofilament dermal threads. Settings and Design: A prospective observational study in a tertiary hospital was conducted between January 2019 and February 2020 after institutional ethical clearance and patient consent. Materials and Methods: 25 adults between 40 and 65 years of age reporting for infero-lateral periorbital rejuvenation and opting for dermal threads, with no history of aesthetic treatment in this region for the past three months were included after their informed consent. 10 monofilament dermal threads (5 each in lateral and infraorbital) in either periorbital region were inserted. Cases were assessed with Lemperle's wrinkle scale and visual analog scale (VAS) and photographic record maintained before procedure and after 16 weeks of procedure. Change in wrinkle grade was analysed using paired t-test and VAS was used to assess patient's perception of the result. Results: 25 cases were included in the study, 21 completed the follow-up and 4 were lost to follow up. The mean preprocedure wrinkle score was 2.29 and postprocedure mean scores were 1. This finding was statistically significant. 16 cases were satisfied with their textural improvement (VAS >+2) while 4 reported mild improvement (VAS 2+) and 1 reported no improvement. Side effects observed were bruising in two cases and thread displacement in one case within 24 hours. Conclusions: Polydioxanone monothreads offer an alternative aesthetic procedure for periorbital rejuvenation.

Efficacy and Safety of Using Noninsulated Microneedle Radiofrequency Alone versus in Combination with Polynucleotides for Treatment of Periorbital Wrinkles.

INTRODUCTION: A few studies have evaluated the efficacy and safety of noninsulated radiofrequency microneedling (RFMN) to treat periorbital wrinkles in Asian patients. Recently, wound healing accelerators, polynucleotides (PNs), have received attention in wound management. However, their efficacy and safety have not been fully elucidated following RFNM. This study aimed to evaluate the efficacy and safety of noninsulated RFMN for periorbital wrinkles and the synergistic effect of PNs after RFMN. METHODS: Thirty subjects with Fitzpatrick skin types III to V and facial wrinkles (Fitzpatrick grades I and II) were enrolled. All volunteers were treated over the entire face with noninsulated RFMN for three sessions at 2-week intervals. The left and right sides of each patient's face were randomly assigned to receive PNs (treatment group) or normal saline solution (control group). The indentation and maximum depth of wrinkles were objectively measured using Antera 3D. Subjective self-evaluations were obtained at baseline, 2 weeks after the third treatment, and at 1, 2, 3, and 6 months after the final treatment. In addition, pain scores, immediate reactions, and other adverse effects were evaluated. RESULTS: Twenty-nine subjects completed the treatment protocol. Most presented with grade II wrinkling (69%). At 2-month follow-up, Antera 3D image analysis revealed faster improvement for the treatment group. At 6-month follow-up, the majority of subjects reported an improvement of 25-75% in their periorbital wrinkles. The average pain score was 2.2 out of 10. No serious adverse events (infection, pigmentary alteration, persistent erythema, or scarring) were observed. CONCLUSIONS: Noninsulated RFMN is safe and effective for treating periorbital wrinkles and can be used as a modality for transdermal drug delivery. Topical polynucleotides as an adjunctive treatment provide additional benefits for periorbital wrinkle treatment. TRIAL REGISTRATION NUMBER: TCTR20201105007.

Synergistic effect of microneedle-delivered extracellular matrix compound and radiofrequency on rejuvenation of periorbital wrinkles.

Background: A combination of minimally invasive modalities can induce collagen regeneration more quickly and promote the penetration of topical agents, thus promoting skin rejuvenation. In this study, we aimed to investigate the synergistic efficacy of extracellular matrix compound (ECM-C) via microneedle (MN) and radiofrequency (RF) on periorbital wrinkles. Method: A total of 25 participants with periorbital wrinkles were selected for this study. The left and right side of the periorbital area was randomly given ECM-C via MN or ECM-C via MN combined with RF. MN combined with ECM-C treatment was given 5 times at 2 weeks intervals, whereas RF treatment was given 3 times at 4-week intervals. The following items were assessed: wrinkles by VISIA® system; biophysical parameters such as skin hydration, transepidermal water loss (TEWL), erythema index, and melanin index by CK multiple probe adapter; and skin elasticity and skin thickness by DermaLab Combo® photographs were taken at the baseline and 2 weeks after the last treatment. Subjective assessments, such as Crow's Feet Grading Scale (CFGS) and Global Aesthetic International Scale (GAIS), were also recorded. Result: A total of 25 participants with an average age of 43 years participated in this trial. Periorbital wrinkles on both sides decreased after the treatment, and the side treated with ECM via MN and RF showed better improvement than the other side with ECM-C via MN alone. Skin hydration increased after the treatment on both sides. TEWL, skin erythema, and skin melanin indexes were not changed. Skin elasticity and skin thickness increased more on the side of ECM-C via MN and RF than on the other side of ECM-C via MN alone. The evaluation scores for CFGS improved on either side; however, no difference was found for CFGS and GAIS between intergroup comparisons after the treatment. Conclusion: The objective assessment of wrinkles, elasticity, and thickness of periorbital skin improved more on the side with ECM-C treatment via MN combined with RF than on the other side of ECM-C treatment via MN only. However, no statistically significant difference was found between the subjective CFGS and GAIS evaluation of the two sides.

Clinical efficacy of different therapeutic modes of CO2 fractional laser for treatment of static periocular wrinkles in Asian skin.

BACKGROUND: Periocular fine lines and wrinkles usually appear as a first visible sign of facial aging. Fractional ablative laser has been used to treat periorbital wrinkles. OBJECTIVE: To compare the efficacy on treatment of static periorbital wrinkles using different emission modes of CO2 fractional laser. METHODS: A total of 30 patients with static periorbital wrinkles were enrolled. The subjects were randomly assigned into two split-face groups: One side was treated with a deep (n = 15) or mid-mode of CO2  superficial laser (n = 15), and the other side of periocular region was treated by a fusion mode in combination of both modes (n = 30). RESULTS: The patients in three groups showed significant improvements on indexes of periocular wrinkles, skin textures, and elasticity at three-month follow-up as compared with baseline (p < 0.05). Fusion mode resulted in a significantly progressive improvement on periocular wrinkles at three-month follow-up as compared with one-month follow-up (p < 0.05), which were not observed in other modes. Fusion mode delivered better improvements of periocular wrinkles and skin textures as compared to deep and mid-modes at three-month follow-up (p < 0.05). Fusion mode also resulted in better scores of global esthetic improvement scale and patient satisfaction as compared to other modes at both follow-ups. CONCLUSION: The fusion mode has a synergistic effect in periorbital static wrinkle treatment, which is worthy of further evaluation and investigation.

Hydrogel plus growth factors treatment after 2940nm erbium:YAG lattice laser improves periorbital wrinkles and wound healing: a case report.

Skin aging is an inevitable physiological process and periorbital wrinkling is an active sign of the process. Laser therapy is an effective method for improving periorbital wrinkles and wound care after laser therapy can accelerate the wound healing process. This case report describes a typical case of a 47-year-old male that presented with a 10-year history of gradually-worsening bilateral periorbital wrinkles. These were treated using a 2940 nm erbium (Er):YAG lattice laser combined with recombinant bovine basic fibroblast growth factor (bFGF) gel and hydrogel (HG) treatment on the left side of his face compared with laser therapy and bFGF gel on the right side of his face. HG combined with bFGF gel treatment after 2940 nm Er:YAG lattice laser therapy improved postoperative swelling and pigmentation compared with bFGF gel alone; and it promoted periorbital wrinkle improvement and wound healing. In conclusion, HG combined with GFs after laser therapy could be an alternative therapy for periorbital wrinkles.

Novel topical dermal repair: A clinical analysis.

BACKGROUND: There is an increasing interest in and demand for noninvasive anti-aging treatments, and cosmeceuticals are an effective adjunct treatment to in-office cosmetic treatments. OBJECTIVE: This study evaluates the short-term cosmetic benefits of a topical anti-wrinkle cream (Ultrascript Dermal Regenesis, Montclair, NJ) and a topical evening DNA repair serum (Dermal DNA Repair Serum with the active ingredient AC-11 from Optigenex INC). METHODS: Fourteen women of all Fitzpatrick skin types were randomized to receive either the topical anti-wrinkle cream (AM cream) only or the AM cream and the topical evening DNA repair serum (PM serum) for 16 weeks. Subjects noted their subjective improvement in wrinkles, pore size, hyperpigmentation, and overall skin quality. Two blinded physicians evaluated the appearance of wrinkles pre- and postapplication of the AM cream. RESULTS: Participants who applied the AM cream only reported subjective improvement in wrinkles and overall quality of their skin. Immediate improvement of wrinkles was seen after the application of the AM cream. Subjects who applied both the AM cream and PM serum noted improvement in pore size. CONCLUSION: This novel anti-wrinkle cream is a safe and effective topical treatment for the immediate, but short-term improvement of wrinkles. Prolonged use of the cream and continued follow-up may show additional long-term benefits.

The effectiveness of imiquimod 5% cream as an anti-wrinkle treatment: A pilot study.

BACKGROUND: Imiquimod 5% cream is currently approved to treat several dermatologic conditions including actinic keratoses (AK), superficial basal cell carcinoma (sBCC), and genital warts. However, there are numerous studies published on the alternative off-label uses of imiquimod cream. Photoaging of facial skin is an important use for topical skin treatments, yet few studies have evaluated the effect of imiquimod cream for this dermatological condition. METHODS: This was a prospective, noncomparative pilot study. We included 15 healthy subjects; out of them, 11 subjects completed the study. The subjects were instructed to apply imiquimod 5% cream to the periorbital area on three nonconsecutive days per week for eight consecutive weeks. Photographs were obtained at baseline and after 8 weeks of treatment. Improvement in overall periorbital skin appearance was assessed by an independent investigator who compared the baseline and post-treatment clinical photographs. In addition, post-treatment self-assessment was completed by the subjects using a 5-point Likert scale. RESULTS: Eleven of the 15 subjects completed the 8-week regimen. Eight participants (72.7%) noticed at least a fair improvement in periorbital skin changes based on the self-assessed 5-point Likert scale. Quartile score was also assessed by the investigator which indicated that seven subjects (63.6%) had at least 26% improvement. Based on Fitzpatrick wrinkle-scoring system, there was a significant reduction in the subjects' wrinkle severity following treatment (6.8 [mean] ± 1.7 [SD] vs 4.6 ± 2.5 [P < 0.005]). CONCLUSIONS: Imiquimod 5% cream may be a safe alternative anti-aging treatment. Larger scale studies are needed to confirm these results.

Nitrogen plasma skin regeneration for the treatment of mild-to-moderate periorbital wrinkles: A prospective, randomized, controlled evaluator-blinded trial.

BACKGROUND: Nitrogen plasma skin regeneration is a novel device that produces heat to the skin, resulting in the production of new collagen. Because of lower energy with safer skin damage and lesser adverse effects who have high Fitzpatrick's skin type especially Thais, this technique is very interesting for clinical application for skin esthetic treatment. However, this treatment has yet been empirically studied as the treatment for mild-to-moderate periorbital wrinkles. OBJECTIVES: This study aimed to evaluate clinical efficacy of nitrogen plasma for the treatment of mild-to-moderate periorbital wrinkles. METHODS: Eighteen volunteers were enrolled. Each volunteer was randomized to receive nitrogen plasma treatment on one side of periorbital wrinkles with three sessions at a three-week interval and compared with contralateral side without treatment. Photographic examination, skin wrinkle (SEw) score, melanin index, patients' satisfaction score, side effect, and pain score were reported. RESULTS: At over fourteen weeks, all volunteers completed the study. Treatment with nitrogen plasma group had significantly better improvement for periorbital wrinkles score by Lemperle scale, skin wrinkle (SEw) score by Visioscan® VC 98, and the melanin index by Mexameter® than the control groups (P = 0.004, P < 0.001, P < 0.001, respectively). This study also showed significantly greater satisfaction score to favor the nitrogen plasma treatment group than the control group (P < 0.001). The short-term adverse effects included erythema, scaling, temporary hyperpigmentation, pruritus, and dryness. CONCLUSION: Nitrogen plasma skin regeneration is effective and safe for the treatment of mild-to-moderate periorbital wrinkles and darkening.

Usefulness of Monopolar Thermal Radiofrequency Treatment for Periorbital Wrinkles.

BACKGROUND: Over the past 10 years, monopolar radiofrequency (MRF) technology has been widely used by dermatologists as a valuable modality to effectively tighten and rejuvenate photoaged skin. It also has the benefit of a short recovery time. OBJECTIVE: Using an objective parameter, this study aimed to assess the efficacy and safety of MRF, which is the basic modality of radiofrequency technologies, for treatment of periorbital wrinkles in Korean patients. METHODS: We enrolled 70 middle-aged female patients with periorbital wrinkles for this study. Each patient underwent triple sessions of MRF treatment in the periorbital region, separated by 2-week intervals. Clinical photographs were obtained, and the areas of wrinkles were measured using a Robo Skin Analyzer CS50 (Inforward Inc., Japan) at baseline and 4 weeks after the final treatment session. RESULTS: Significant reduction in the mean area of periorbital wrinkles was detected at 1-month follow-up (80.64±28.96 mm2) compared to baseline (95.08±31.93 mm2). The improvement ratio of the wrinkle area was 15.19%. Pain during procedure seemed to be tolerable without any local anesthesia for all patients. Transient mild erythema was the only side effect reported during the study. CONCLUSION: In conclusion, MRF could still be an attractive modality for Korean patients with periorbital wrinkles if the treatment is conducted repeatedly with sufficient energy and proper intervals.

Phototherapy with Light Emitting Diodes: Treating a Broad Range of Medical and Aesthetic Conditions in Dermatology.

Within the field of dermatology, advances in the use of light emitting diodes (LEDs) have led to their clinical application for a variety of medical and cosmetic uses. Of note, one phototherapy device has demonstrated beneficial effects over a range of clinical applications (Omnilux™; GlobalMed Technologies, Glen Ellen, California). The study included a literature review of published studies. Using LEDs with frequencies of 415nm (blue), 633nm (red), and 830nm (infrared), this device has demonstrated significant results for the treatment of medical conditions, including mild-to-moderate acne vulgaris, wound healing, psoriasis, squamous cell carcinoma in situ (Bowen's disease), basal cell carcinoma, actinic keratosis, and cosmetic applications. Although photodynamic therapy with the photosensitizer 5-aminolevulinic acid might cause stinging and burning, phototherapy is free of adverse events. We determined that phototherapy using LEDs is beneficial for a range of medical and aesthetic conditions encountered in the dermatology practice. This treatment displays an excellent safety profile.

Safety, efficacy, and usage compliance of home-use device utilizing RF and light energies for treating periorbital wrinkles.

BACKGROUND: The aging process is often associated with undesirable effects on facial skin such as skin redundancy, reduction of elasticity, and increased wrinkling. Radiofrequency (RF) and light-emitting diodes (LEDs) are widely used, clinically proven technologies for skin rejuvenation. STUDY OBJECTIVE: This study aimed to evaluate the safety, efficacy, and usage compliance of the home-use device, utilizing RF and LED energies, for self-treatment of periorbital wrinkles and improvement of skin appearance. STUDY DESIGN: Thirty-three subjects performed 21 treatment sessions every other day, over 6 weeks on the periorbital areas. In addition, two maintenance treatments were conducted 1 and 2 months following treatment end. Each subject served as his/her own control, comparing results before treatment, and 3 months following treatment end. RESULTS: Thirty subjects completed the study. A blinded, independent photographs assessment of three dermatologists demonstrated an average reduction of 1.49 Fitzpatrick scores (P < 0.001). Analysis revealed improvement (downgrade of at least 1 score) in almost all subjects. No unexpected adverse events were reported. Post-treatment erythema was seen in all subjects and disappeared within 1 h. In some subjects, post-treatment edema was detected and resolved within 24 h. High satisfaction with the device operation, ease of treatments, safety, and wrinkle reduction was reported. CONCLUSIONS: The Silk'n Home Skin Tightening (HST) device offers a safe and effective in-home noninvasive technique to improve the appearance of age-related periorbital wrinkles.

Antes del tratamiento, hubo mayor frecuencia de arrugas moderadas (estudio: 42,9 por ciento; control: 51,4 por ciento) y severas (estudio: 42,9 por ciento; control: 34,3 por ciento). Posterior a la intervención, se constató una mejoría superior en el grupo estudio con cambios significativos en ambos conjuntos tratados (p< 0,001). Se presentó una complicación del grupo control (2,9 por ciento); 100 por ciento quedó satisfecho y los resultados fueron buenos en el grupo estudio (94,3 por ciento) y regulares en igual proporción del control con diferencias significativas (p< 0,001). Conclusiones: La lipotransferencia asistida con células madre ofrece resultados superiores a la convencional en el rejuvenecimiento periorbitario(AU)

Objective: To evaluate the effect of adipose tissue-derived stem cells in the treatment of periorbital wrinkles. Methods: Randomized double-blind comparative trial in the Plastic Surgery Service of the Clinical Surgical Hospital "Hermanos Ameijeiras" in the period since September/2019 until July/2021. The sample consisted of 70 patients who met the selection criteria and were distributed into two treatment groups. Results: Women predominated (88.6 percent) with an average age of 47 years with no significant differences between the treatment groups. The 60.0 percent of the study group and 62.9 percent of the control group presented skin phototype II with no significant differences between the groups (p= 0.855). The highest percentage of aging corresponded to III and the lowest to IV (14.3 percent vs. 20.0 percent), with no significant differences between the groups (p= 0.487). Before treatment, there was a higher frequency of moderate (study: 42.9 percent; control: 51.4 percent) and severe wrinkles (study: 42.9 percent; control: 34.3 percent). After the intervention, there was a superior improvement in the study group with significant changes in both treated groups (p< 0.001). There was one complication in the control group (2.9 percent). 100 percent were satisfied and the results were good in the study group (94.3 percent) and regular in equal proportion of the control with significant differences (p< 0.001). Conclusions: Stem cell-assisted lipotransfer offers superior results to conventional lipotransfer in periorbital rejuvenation(AU)

Photodynamic therapy using a new formulation of 5-aminolevulinic acid for wrinkles in Asian skin: A randomized controlled split face study.

BACKGROUND: Photodynamic therapy (PDT) with intense pulsed light (IPL) was proven effective for photorejuvenation. Recently, a new formulation of 0.5% 5-aminolevulinic acid (ALA) liposomal spray has been available. We designed a randomized split face study to evaluate usefulness and safety of IPL-PDT using a liposomal spray for periorbital wrinkles in Asians. METHODS: Patients received three treatments every 3 weeks. The half of the face was treated with IPL-PDT and the other half with long pulsed Nd:YAG laser (LPNY). Skin fluorescence was measured using a spectrophotometer for the guidance of PDT treatment. Wrinkle score was marked by two-blinded independent dermatologists. RESULTS: One patient dropped out due to 3-d lasting erythema on PDT side. The difference of mean reduction in lower and lateral periorbital wrinkle score on PDT side between the first and the last visit was statistically significant (p = 0.008 and p = 0.001, respectively). Lateral periorbital wrinkles treated with PDT showed better results than LPNY-treated sides. Twenty-five percent of patients reported good to excellent outcomes. CONCLUSION: This study demonstrated that PDT with a liposomal spray provided modest wrinkle reduction without serious adverse effect and it might be a promising treatment modality for wrinkle treatment in Asians.

Clinical photographs were obtained, and the areas of wrinkles were measured using a Robo Skin Analyzer CS50 (Inforward Inc., Japan) at baseline and 4 weeks after the final treatment session. RESULTS: Significant reduction in the mean area of periorbital wrinkles was detected at 1-month follow-up (80.64±28.96 mm2) compared to baseline (95.08±31.93 mm2). The improvement ratio of the wrinkle area was 15.19%. Pain during procedure seemed to be tolerable without any local anesthesia for all patients. Transient mild erythema was the only side effect reported during the study. CONCLUSION: In conclusion, MRF could still be an attractive modality for Korean patients with periorbital wrinkles if the treatment is conducted repeatedly with sufficient energy and proper intervals.

Efficacy of Biodegradable Microneedle Patches on Periorbital Wrinkles / 대한피부과학회지

BACKGROUND: Biodegradable microneedle technology is a recently developed method to deliver medical and pharmaceutical medications into the skin, and is expected to yield better treatment results than topical application methods. OBJECTIVE: To evaluate the efficacy of hyaluronic acid (HA)-based microneedle patches and epidermal growth factor (EGF)-containing microneedle patches on periorbital wrinkle improvement. METHODS: A 20-week randomized, double-blind study was performed. Twenty-five Korean patients with periorbital wrinkles and a wrinkle severity rating scale (WSRS) score above 2 were enrolled into the study. The patients completed the study using the two different types of patches on each side of the designated periorbital wrinkles area every other day for 8 weeks. Patients were requested for an additional 12-week follow up. Wrinkle improvements were assessed by WSRS score, subjective patient satisfaction score, and imaging analysis using the visiometer, corneometer, cutometer, and mexameter, respectively (Courage&Khazaka, Cologne, Germany). RESULTS: Both the HA-based microneedle patch and EGF-containing HA-based microneedle patch had positive effects on WSRS score, patient satisfaction levels, and corneometer result with statistically significant differences. No significant side effects were noticed. CONCLUSION: With respect to efficacy, no statistical difference between the two groups were noted, indicating that the anti-wrinkle effects of the microneedle patch may solely be due to the HA rather than the EGF.
