RESUMO
BACKGROUND: Vitiligo lesions are often challenging to repigment with conventional medical therapies. Surgical autologous melanocyte transfer methods can be utilized for stable vitiligo but demand specialized skills and equipment. A point-of-care autologous cell harvesting device was designed enabling simple preparation of autologous skin cell suspension (ASCS) containing melanocytes, keratinocytes, and fibroblasts providing a straightforward approach for cellular transplantation. OBJECTIVE: To evaluate the safety and effectiveness of ASCS for repigmentation of stable vitiligo lesions among adults. METHODS: A US multicenter, randomized, within-subject controlled trial compared ASCS to NB-UVB only (Control) in similar vitiligo lesions. ASCS was applied after laser skin resurfacing and followed by NB-UVB treatment. The primary effectiveness endpoint was the proportion of lesions achieving ≥80% repigmentation at week-24. Repigmentation durability was assessed at week-52. RESULTS: Among 25 subjects, 36% of ASCS-treated lesions achieved ≥80% repigmentation at week-24 compared to 0% for Control (p<0.025), with durability through week-52. The safety profile of ASCS was acceptable, with favorable patient- and investigator-reported outcomes. LIMITATIONS: Study sample size limited robust subgroup analyses. CONCLUSION: Application of ASCS is a safe and effective treatment for repigmentation of stable vitiligo lesions with the potential to improve health-related quality of life and reduce burden of disease.
RESUMO
BACKGROUND: Acne scarring is an unfortunate sequela affecting up to 95% of patients with acne and carries profound psychosocial impact. Both nonablative fractional lasers (NAFL) and microneedling with radiofrequency (MNRF) have demonstrated comparable efficacy in the treatment of atrophic acne scars. OBJECTIVE: To determine whether alternating NAFL and MNRF is superior to NAFL alone in the treatment of atrophic acne scars. METHODS AND MATERIALS: This was a prospective, single-center, double-blinded, split-face clinical trial. Twenty patients with atrophic acne scars who had their facial halves randomized to receive either NAFL alone or NAFL alternating with MNRF. Patients received 4 total treatments at 4-week intervals. RESULTS: Ninety days after the final treatment, both facial halves demonstrated a significant improvement in the mean global échelle d'évaluation clinique des cicatrices d'acné (ECCA) score from baseline ( p < .001 for both halves). The average percentage improvement at the final end point was 20% to 30% from baseline. No significant difference was noted between facial halves for mean global ECCA score or percentage improvement at any time point. CONCLUSION: Although both NAFL and MNRF are safe and effective in the treatment of atrophic acne scars, alternating NAFL and MNRF does not seem to be superior to NAFL alone.

BACKGROUND: Cosmetic facial tattoos have proven difficult to remove despite advancements in laser technology. OBJECTIVE: Review safety and efficacy of picosecond laser removal of cosmetic facial tattoos. METHODS MATERIALS: Retrospective chart review from January 2015 to January 2022 of patients undergoing tattoo removal of facial cosmetic tattoos. RESULT: A total of 33 patients were included in the review. The average number of treatments to obtain satisfactory results was 3. Sixty 6 percent of subjects were rated as "very much improved" with 76% to 100% of the tattoo removed and 34% of subjects were rated "much improved" with 51% to 75% of the tattoo removed. Thirty percent of subjects experienced unexpected changes in the tattoo color after initial treatment with 1,064-nm picosecond laser. CONCLUSION: Picosecond laser is an effective and safe treatment for cosmetic tattoos, and it highlights the underreported unmasking of an orange color postlaser treatment that can be successfully treated with a 532-nm PS laser.

BACKGROUND: There are limited studies evaluating topical cosmetic skincare products following cosmetic facial injections. OBJECTIVE: An open-label study assessed a novel medical-grade topical skincare regimen following cosmetic facial injections. METHODS: The study enrolled 20 women with moderate to severe facial photodamage who used non–physician-dispensed skincare products and pre-elected to receive facial neuromodulator and hyaluronic acid (HA) dermal filler injections. All subjects continued regular skincare through week 4 after facial injection, then switched to the novel regimen (growth factor product, TNS Advanced+; day/night antioxidant serum system, Lumivive; HA-based hydrator, HA5; and basic skincare components) through week 16. RESULTS: At week 4, significant (P≤0.05) improvements from baseline were seen for multiple investigator-graded skin quality parameters, including overall photodamage, tactile roughness, and skin tone evenness, as well as fine and coarse lines/wrinkles. After switching to the novel regimen, additional significant improvements in overall skin quality and forehead, cheek, and perioral fine lines/wrinkles were observed at week 8 (all P≤0.05 vs week 4), which continued through week 16. CONCLUSION: This study highlights the importance of topical skincare in conjunction with cosmetic facial injections to holistically optimize overall skin quality and appearance.

BACKGROUND: Significant improvement in skin tone was reported after topical application of a facial cream (CALECIM® Professional Multi-Action Cream, CALECIM Cosmeceuticals, Singapore) containing conditioned media (CM) derived from Red Deer Umbilical Cord Lining Mesenchymal Stem Cell (RD-CLMSC) culture. This study investigates the paracrine effects of RD-CLMSC-CM on human dermal fibroblasts (HDF) to understand how it may increase skin turgor and elasticity. Skin aging is associated with lower levels of extracellular matrix components such as hyaluronic acid (HA) and elastin, resulting in poor skin turgor and elasticity. Histochemical staining followed by photocolorimetry demonstrated that RD-CLMSC-CM upregulated HDF expression of elastin by 56% and HA by 83% compared with DMEM/10% Fetal Calf Serum (FCS).To further quantify the effects of CM, a proliferation assay was used to assess HDF response to RD-CLMSC-CM exposure. Exposure to RD-CLMSC-CM resulted in the highest increase in HDF proliferation over DMEM/10% FCS (113%) followed by Human (H)-CLMSC-CM (112%), then Human Foreskin Fibroblast (FSF)-CM (16%).These experimental results demonstrate both the cross-species efficacy and lack of toxicity of RD-CLMSC-CM on HDF. These pre-clinical studies also suggest the clinical effects of RD-CLMSC-CM on skin turgor may be related to increased HA and elastin production by HDF, as well as enhanced proliferation.

BACKGROUND: After laser resurfacing, it is imperative that an appropriate postoperative regimen is followed for optimal wound healing. There is currently no consensus about which agents should be used. OBJECTIVE: To evaluate the safety and efficacy of a novel macrophage-activating gel in a Phase 2B trial to be used after fractionated ablative laser resurfacing of the chest. MATERIALS AND METHODS: Forty-two adults who received fractionated CO2 laser resurfacing of the chest were randomized (active or placebo) for 5 consecutive days after procedure. Skin quality at baseline and follow-up was assessed by a blinded evaluator using the Fitzpatrick-Goldman Wrinkle Scale. Subject satisfaction with skin healing and quality was also assessed. RESULTS: At 28 days according to the Fitzpatrick-Goldman Wrinkle Scale, 85% of subjects achieved an improvement of at least 33% for the active group versus 50% in the placebo group (absolute difference 35%; p = .04). Similarly, 75% of subjects achieved an improvement score of at least 33% in elastosis in the active group versus 35% in the placebo group at 28 days (40% absolute difference; p = .011). CONCLUSION: This study confirms the potent effects of the novel macrophage-activating gel for optimization of skin healing and quality after laser resurfacing of the chest.

BACKGROUND: Radiofrequency microneedling (RFMN) and nonablative fractional 1,550-nm erbium:glass lasers (NAFLs) have been reported to be used with success in neck rejuvenation. There are no head-to-head trials to compare these modalities. OBJECTIVE: The purpose of the study was to compare the efficacy and safety of radiofrequency microneedling and nonablative fractional 1,550-nm erbium:glass lasers for the rejuvenation of the neck. METHODS: This was a single-center, randomized, investigator-blinded clinical trial. A total of 21 subjects were randomized into 2 groups, NAFL and RFMN; subjects received 3 treatments 4 weeks apart and were followed up 12 weeks after last treatment. RESULTS: Subjects in NAFL and RFMN groups showed 42.1% and 8.6% improvement in the Fitzpatrick-Goldman Wrinkling Score, respectively, 41.3% and 16.3% improvement in the elastosis score, respectively. Subjects in the NAFL 1,550-nm erbium:glass group showed significantly better blinded investigator Fitzpatrick-Goldman Wrinkling and Elastosis scores; subjects in the RFMN groups showed a more significant reduction in the Horizontal Neck Wrinkle Severity Score. There was a trend for higher patient satisfaction with the NAFL. CONCLUSION: This study showed that both treatments resulted in significant improvement in wrinkling and elastosis scores; the NAFL treatment was associated with significantly better blinded investigator Fitzpatrick-Goldman Wrinkling and Elastosis scores and better subject satisfaction.

BACKGROUND: Sclerotherapy is commonly performed for elimination of reticular and telangiectatic leg veins. There are several variations in practice, from the preparation to post-therapy directives. OBJECTIVE: To critically examine the misconceptions of sclerotherapy for aesthetic indications. MATERIALS AND METHODS: This review assesses evidence for and against each of the most common myths regarding sclerotherapy for aesthetic indications. RESULTS: Sclerotherapy can be safely used to treat veins in areas other than the lower extremities, with the exception of the face. Laser therapy is not superior to sclerotherapy for the treatment of small telangiectatic veins on the lower extremities. The type of syringe used to produce foam sclerotherapy is an important procedural consideration. After sclerotherapy, graduated compression stocking usage is a vital part of the procedure. Detergent sclerotherapy agents are similar, but not equivalent. Touch-up treatments after sclerotherapy should not be performed for 2 months post-treatment. Foam sclerotherapy does not have a high risk for air emboli. It is not advisable to treat the leg veins in "sections." Finally, one cannot reliably treat the telangiectatic veins without treating the feeding reticular veins for a satisfactory result. CONCLUSION: Many aspects of sclerotherapy have existing evidence to dictate best clinical practice.

BACKGROUND: Vascular occlusions that threaten skin integrity, although not an emergency like those that threaten a patient's vision, is an urgent situation. Accurately interpreting physical examination findings is paramount. The use of high-dose, pulsed hyaluronidase is the mainstay of therapy; however, adjunctive measures that may optimize clearance of an occlusion and/or skin barrier repair such as the use of image guidance and hyperbaric oxygen should be considered. OBJECTIVE: To provide a review of the literature on the treatment of vascular occlusions threatening skin barrier integrity and develop a step-wise treatment guide. MATERIALS AND METHODS: The authors searched PubMed for peer-reviewed studies, consensus statements, case series, and case reports using a variety of keywords. RESULTS: Twenty-six articles focusing on vascular occlusions threatening the skin barrier were reviewed. The authors collectively agreed on treatments to reverse vascular occlusions and restore the skin barrier. The importance of high-dose, pulsed hyaluronidase was clear. Therapies that lacked evidence such as sodium thiosulfate were also revealed. CONCLUSION: A vascular occlusion that threatens skin integrity is an urgent matter which requires accurate interpretation of physical examination findings that will help guide intervention. High-dose, pulsed hyaluronidase along with adjunctive measures performed in a step-wise manner is key to an optimal outcome.

INTRODUCTION: Jawline augmentation with calcium hydroxylapatite has not yet been evaluated in a prospective study with a split-face design. This study aims to perform the first randomized controlled, split-face study on the efficacy and safety of calcium hydroxylapatite for jawline augmentation using the needle and cannula technique. OBJECTIVE: To perform the first randomized controlled, split-face study on the efficacy and safety of calcium hydroxylapatite for jawline augmentation using the needle and cannula technique. MATERIALS AND METHODS: This is a single-site, randomized, evaluator-blind trial enrolling a total of 10 healthy subjects with at least Grade 1 (mild) on a 4-point Jawline Scale. One side of the face was randomized to receive 1 to 2 syringes of calcium hydroxylapatite with lidocaine (total of 3 mL) for correction of wrinkles and folds along the jawline using both the cannula and needle method, and a balancing treatment will be performed 1 month later. Blinded investigator and subject evaluations will be performed immediately after treatment and at the 30-, 60-, and 90-day visits. RESULTS: Ten subjects were enrolled and completed the trial. There was a improvement in the degree of wrinkling and skin sagging in the 4-point Jawline Scale, with an average of a 1.3-point improvement in the scale on the day of treatment and at the Day 30 visit, which remained improved greater than baseline after 3 months as graded by blinded investigators. The Clinician Global Aesthetic Improvement Score for the treated side versus control, as assessed by blinded investigators, demonstrated a improvement with a 2.3-point improvement on the 5-point scale, and by the final visit on Day 90, most patients had a much improved appearance from baseline. CONCLUSION: This study demonstrates that calcium hydroxylapatite is effective and safe for restoration and augmentation of the jawline using the unique needle and cannula technique.

BACKGROUND: In total, 2.7 million injectable filler treatments were performed in 2019 in the United States. Although generally considered to be a safe treatment modality, adverse events may occur in rare situations. OBJECTIVE: Analyze serious adverse events from injectable filler treatments, including infections, cutaneous necrosis, blindness, or delayed-onset nodule formation, spanning 11 years for 3 board-certified dermatologists and review their incidence, management, and outcomes. MATERIALS AND METHODS: A retrospective analysis was performed of injectable filler treatments spanning 11 years at a multipractitioner outpatient clinic. Serious adverse events were identified, and treatment measures were documented. A literature search was performed to determine recent trends and outcomes for comparison. RESULTS: Between January 2009 and August 2020, 18,013 mL of injectable filler was administered to 7,659 patients. Of the 18,013 mL administered, 74.1% comprised hyaluronic acid derivatives, 19.19% poly-l-lactic acid, and 6.71% calcium hydroxylapatite. Four serious adverse events were identified. Three events were delayed-onset skin nodule formation. One adverse event was related to vascular compromise and subsequent cutaneous necrosis. After appropriate treatment, all adverse events resolved without significant long-term sequelae. CONCLUSION: Serious adverse events associated with injectable fillers, when performed by board-certified dermatologists, are extremely rare and can be successfully managed with appropriate treatment.

BACKGROUND: Background: Skin exposure to ultraviolet radiation (UVR) causes DNA damage, which can lead to mutagenesis, carcinogenesis, cellular death, and photoaging. Signs of photoaging include wrinkling, erythema, skin laxity, uneven skin texture, and hyperpigmentation. Photolyase is an exogenous DNA repair enzyme that can restore DNA integrity when applied topically to human skin. Antioxidants also play a key role in reducing UVR-associated molecular damage. OBJECTIVE: To assess the efficacy and safety of a tinted mineral-based sunscreen containing 10.7% zinc oxide (SPF50) with the active ingredients photolyase, antioxidants (Peptide Q10), and peptides in both protecting and repairing signs of photoaging. METHODS: In an open-label, single-center, 12-week study, patients aged 35–55 years and Fitzpatrick skin phototypes II–IV applied the sunscreen daily for 84 days. VISIA photography was performed at baseline as well as 6- and 12-week follow-ups. At each visit, the investigator and subject evaluated clinical photoaging parameters including overall photodamage, fine lines/wrinkles, coarse lines/wrinkles, skin tone evenness, tactile roughness, and radiance. RESULTS: The Investigator Global Aesthetic Improvement Scale (IGAIS) found that 63% of patients showed improvement at week 6 and 81% at week 12. The Subject Global Aesthetic Improvement Scale (SGAIS) showed 58% and 62.5% of patients reported the appearance of their skin was improved at week 6 and 12, respectively. Overall, there was a statistically significant improvement in skin radiance as well as improvement in overall facial aesthetics reported by both investigators and subjects. CONCLUSION: This tinted mineral based SPF50 sunscreen containing photolyase, antioxidants, and peptides is effective at repairing some clinical signs of photoaging and is well-tolerated for daily use.

BACKGROUND AND OBJECTIVES: The use of picosecond laser in dermatology was originally focused on optimizing the removal of unwanted tattoos. Subsequent advances in this technology have broadened its clinical indications to include treatment of benign pigmented lesions, photodamage, melasma, and scar revision. In this systematic review, evidence-based recommendations are developed for the use of picosecond laser in dermatology. STUDY DESIGN/MATERIALS AND METHODS: A comprehensive search of the English language literature was performed up to and including November 2019. Relevant citations were individually evaluated, synthesized, and categorized based on the Level of Evidence. With the addition of the authors' combined clinical experience, clinical recommendations were developed. RESULTS: After application of inclusion and exclusion criteria, a total of 77 unique studies were evaluated. Treatment of benign pigmented lesions was associated with level I-IV evidence; rejuvenation was associated with level II evidence; melasma was associated with level II evidence; scar revision was associated with level II-III evidence; tattoo removal was associated with level I evidence. CONCLUSION: Picosecond laser is a safe and effective treatment modality for an increasing range of dermatologic indications. Further development of this technology is warranted. Lasers Surg.

BACKGROUND AND OBJECTIVE: Fractionated lasers are a popular therapeutic option for facial photorejuvenation. In this study, we compare the safety, tolerability, and efficacy of a fractionated frequency-doubled 1064/532 nm picosecond Nd:YAG fractionated picosecond laser (FPL) versus a fractionated 1927 nm thulium fiber laser (TFL) for facial rejuvenation. STUDY DESIGN/MATERIALS AND METHODS: This was a double-blind, randomized, split-face comparison study involving 20 subjects. Facial halves were randomized to receive either FPL or TFL treatment. Three treatments were delivered at 1-month intervals. Subjects were followed up for 1, 3, and 6 months post-final treatment session and evaluated by blinded, non-treating investigators for dyspigmentation, erythema, keratosis, texture, and rhytids on a standardized scale. Subjects also recorded a quantitative daily diary rating healing progress for 14 days after every treatment session. RESULTS: Statistically significant improvements in elastosis, erythema, keratosis, dyschromia, and skin texture were noted in both treatment groups. There were no significant differences detected in clinical efficacy between the two groups. Subject daily dairies revealed statistically significant differences in tolerability during the immediate 14-day post-operative recovery period. The facial half treated with FPL displayed significantly less redness on days 3 and 4; significantly less swelling on day 5; significantly less crusting on days 1 through 9; significantly less peeling on days 3 through 9; and significantly less itch on days 4 and 7. There were no unexpected adverse effects observed. CONCLUSION: Both FPL and TFL are safe and effective treatment options for facial rejuvenation. FPL may be associated with significantly less downtime. Lasers Surg. Med. © 2020 Wiley Periodicals, Inc.

BACKGROUND: Facial reticular veins can be treated with laser therapy, sclerotherapy, or surgical removal. The use of a 1,064 nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser has been reported to be successful in the treatment of facial reticular veins. OBJECTIVE: To report a large retrospective study examining the efficacy, side effects, and satisfaction of a dynamically cooled, variable spot-sized 1,064 nm Nd:YAG laser for the treatment of facial reticular veins in the periorbital and temporal area. PATIENTS AND METHODS: Contact was made with 100 patients from 2006 to 2019 who underwent treatment with a 1,064 nm Nd:YAG laser for facial reticular veins through office follow-up or telephone interviews. Percent resolution of veins, satisfaction, and adverse effects were evaluated. RESULTS: Eighty-nine of the 100 patients ranked their satisfaction with the treatment as 3 or very satisfied. Most patients reported 75% to 100% improvement. The most commonly reported adverse event seen after treatment was mild edema. Sixty-eight percent of patients reported no adverse effects at all. CONCLUSION: The dynamically cooled, variable spot-sized 1,064 nm Nd:YAG laser is a safe and effective treatment for facial reticular veins with minimal side effects. The results are usually immediate and, based on the long-term follow-up, tend to be long lasting.

BACKGROUND: A significant population of aesthetic patients are postpartum women motivated to achieve a more youthful abdomen. Although traditionally, abdominoplasty was the treatment of choice, minimally invasive procedures have grown in popularity because of minimal downtime and the favorable side effect profile. so many women share concerns regarding their postpartum abdominal appearance, a limited number of studies focus specifically on postpartum abdominal rejuvenation. OBJECTIVE: To review pertinent aspects of abdominal anatomy, associated changes with pregnancy, available nonsurgical cosmetic procedures, and to provide our experience to help guide treatment combinations which comprehensively address the concerns of the postpartum patient. MATERIALS AND METHODS: A review of the literature surrounding nonsurgical treatment options for postpartum abdominal lipohypertrophy, muscle changes, tissue laxity, and striae gravidarum, along with the authors' experience in this area are provided. CONCLUSION: This review summarizes available nonsurgical modalities to address postpartum abdominal defects, including procedures that tone muscles, reduce fat, tighten skin, and improve the appearance of striae. Both the published literature and the authors' experience favor a combination of treatments to address the various lamellae affected by pregnancy. Further clinical trials focusing on the postpartum patient would further help create a standardized approach for postpartum abdominal rejuvenation.

BACKGROUND: Aging of the face and upper neck is a complex process characterized by loss of collagen and elastic fibers, resulting in clinical skin laxity. Noninvasive interventions such as monopolar capacitively coupled radiofrequency (MRF) have gained popularity, offering a safer and more convenient alternative to traditional surgical face lift. The latest MRF device features larger tips, vibration, cooling, and impedance matching. OBJECTIVE: We performed the first open-label clinical trial, measuring the efficacy, safety, and patient satisfaction of this device for noninvasive lifting and tightening of the face and upper neck. MATERIALS AND METHODS: Forty subjects 30 to 60 years of age with mild/moderate skin laxity of the face and upper neck were enrolled. After pretreatment with ketorolac 60 mg intramuscular injection, subjects underwent treatment with MRF. Follow-up evaluations were performed on Days 30, 60, and 180. RESULTS: Our study demonstrated that the newest generation MRF produced statistically significant improvement in skin laxity 6 months post-treatment, especially in the jowls and melolabial folds. According to the Investigator Global Aesthetic Improvement Score, 73% of subjects had improvement at 6 months post-treatment. Subject satisfaction and improvement questionnaires supported these findings. CONCLUSION: Our data coupled with the excellent adverse effect profile validates MRF as an attractive treatment modality for facial and upper neck skin laxity.

BACKGROUND: Fibrous septae play a role in contour alterations associated with cellulite. OBJECTIVE: To assess collagenase clostridium histolyticum-aaes (CCH) for the treatment of cellulite. MATERIALS AND METHODS: Two identically designed phase 3, double-blind, randomized studies (RELEASE-1 and RELEASE-2) were conducted. Adult women with moderate/severe cellulite (rating 3-4 on the Patient Reported Photonumeric Cellulite Severity Scale [PR-PCSS] and Clinician Reported PCSS [CR-PCSS]) on the buttocks received up to 3 treatment sessions of subcutaneous CCH 0.84 mg or placebo per treatment area. Composite response (≥2-level or ≥1-level improvement from baseline in both PR-PCSS and CR-PCSS) was determined at Day 71. RESULTS: Eight hundred forty-three women received ≥1 injection (CCH vs placebo: RELEASE-1, n = 210 vs n = 213; RELEASE-2, n = 214 vs n = 206). Greater percentages of CCH-treated women were ≥2-level composite responders versus placebo in RELEASE-1 (7.6% vs 1.9%; p = .006) and RELEASE-2 (5.6% vs 0.5%; p = .002) and ≥1-level composite responders in RELEASE-1 (37.1% vs 17.8%; p < .001) and RELEASE-2 (41.6% vs 11.2%; p < .001). Most adverse events (AEs) in the CCH group were injection site related; few CCH-treated women discontinued because of an AE (≤4.3%). CONCLUSION: Collagenase clostridium histolyticum-aaes significantly improved cellulite appearance and was generally well tolerated.

BACKGROUND: Dyspigmentation and photodamage are common concerns in patients who seek aesthetic consultation. A number of treatment modalities have been utilized to address this issue. 1927 nm thulium fiber laser is a fractionated non-ablative laser that has been shown to be safe and effective in treatment of photoaging. Topical retinoids have been used for over two decades for photoaging to promote epidermal hyperplasia and collagen synthesis and to decrease melanin production. There has been lack of data to support the combination of topical retinoids with laser treatments in the management of facial dyspigmentation and photodamage. OBJECTIVE: The primary objective of this study is to evaluate the benefits and subject satisfaction resulting from use of a 1927 nm thulium fiber laser with and without 0.05% tretinoin lotion for facial dyspigmentation and photodamage. RESULTS: Both groups showed a significant change in Investigator Assessed Overall Hyperpigmentation and Investigator Assessed Overall Photodamage over time (P<0.001). No statistically significant differences were seen between groups at any time point as measured by investigator reported and subject reported efficacy scales except for Subject Global Aesthetic Improvement Scale and Subject Satisfaction at 30 days after laser treatment, at which patients who received 0.05% tretinoin lotion reported a lower level of improvement (2.8 ± 0.86 in the treatment group vs 2 ± 0.85 in the vehicle group, P=0.009) and lower patient satisfaction when compared to the vehicle group (2.87 ± 1.55 in the treatment groups vs 1.53 ± 0.64 in the vehicle group, P=0.001). CONCLUSION: In our study, patients tolerated the combination of 1927 nm thulium fiber laser and 0.05% tretinoin lotion well. Both groups resulted in significant reduction of hyperpigmentation and photodamage.
