Abstract
BACKGROUND Improving the appearance of lentigines on the hands is a key component to hand rejuvenation. Soft tissue fillers revolumize hands, but do not address pigmentary changes. OBJECTIVE: This study investigated the effiacy of a 15% trichloroacetic acid (TCA) + 3% glycolic acid (GA) combination peel in improvement of appearance of hand lentigines. METHODS A prospective evaluator-blinded, split-hand study was performed using a 15% TCA + 3% GA peel to treat patients with hand lentigines. Subjects received a total of 3 treatments at 4-week intervals on 1 hand, with the other hand serving as an untreated control. Final photographs were taken 12 weeks after the last treatment. Two blinded board-certified dermatologists graded improvement in hand lentigines using a 5-point scale. RESULTS Eighteen of 20 patients completed the study (90%). The mean age was 64.4 years (SE 1.6, range 51-71). The mean pain scores were 3.8 (SE 0.4) on a 10-point scale (1 = no pain, 10 = extremely painful). Blinded evaluators correctly identified the after-treatment photographs in 16 patients (88%). Physician and patient-graded mean improvement of lentigines was significant for treated versus control hands ( p < .01). No adverse events were noted. CONCLUSION A series of three 15% TCA + 3% GA peels are effective and safe in the treatment of hand lentigines.

Health Sci Rep 2024; 7:e1930. [PMID: 38410492 PMCID: PMC10895154 DOI: 10.1002/hsr2.1930] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 11/17/2023] [Accepted: 01/15/2024] [Indexed: 02/28/2024] Open
Abstract
Background Solar lentigines are common hyperpigmented lesions typically appearing after 50 years of age and associated with negative psychological effects in affected individuals. Topical depigmenting products, such as hydroquinone and even the Kligman's formula, are usually ineffective for treating lentigines. Stabilized cysteamine has been recently shown to be as effective as the modified Kligman's formula for treating melasma. In this study, we evaluated the therapeutic effect of a stabilized cysteamine on solar lentigines. Methods A vehicle-controlled, double-blind, and randomized study was performed on 30 patients with solar lentigines. Stabilized cysteamine or vehicle control creams were applied on solar lentigines on the dorsum of the hands daily for 12 weeks. Clinical measurements with colorimetry and visual analog scale were performed at baseline, 4, 8, and 12 weeks. Results Statistically significant results were obtained in the cysteamine group versus the vehicle control group. Stabilized cysteamine provided a 40% reduction in colorimetric values (p < 0.002) versus a 2% reduction in the vehicle group (p < 0.405). Cysteamine also provided a 40% reduction in VAS (p < 0.001) versus a 2% reduction in the vehicle group (p < 0.245). Conclusion Significant improvement of solar lentigines was observed after 12 weeks of application of stabilized cysteamine by all evaluation methods. Stabilized cysteamine represents a highly effective topical treatment for solar lentigines and can be considered as one of the first topical therapies effective on this hyperpigmentary disorder.

Abstract
Photoaging is the premature aging of the skin caused by repeated exposure to ultraviolet (UV) rays. The harmful effects of UV rays-from the sun or from artificial sources-alter normal skin structures and cause visible damage, especially in the most exposed areas. Fighting premature aging is one of the most important challenges of the medical landscape. Additionally, consumers are looking for care products that offer multiple benefits with reduced environmental and economic impact. The growing requests for bioactive compounds from aromatic plants for pharmaceutical and cosmetic applications have to find new sustainable methods to increase the effectiveness of new active formulations derived from eco-compatible technologies. The principle of sustainable practices and the circular economy favor the use of bioactive components derived from recycled biomass. The guidelines of the European Commission support the reuse of various types of organic biomass and organic waste, thus transforming waste management problems into economic opportunities. This review aims to elucidate the main mechanisms of photoaging and how these can be managed using natural renewable sources and specific bioactive derivatives, such as humic extracts from recycled organic biomass, as potential new actors in modern medicine.

Abstract
BACKGROUND Solar lentigo (SL) is a benign hyperpigmented spot occurring due to ultraviolet exposure, most commonly in the elderly. We aimed to compare the safety and efficacy of trichloroacetic acid (TCA) peeling with Q-switched laser in the treatment of SLs. METHODS This assessor-blind split-hand randomized controlled trial included 45 patients with symmetric SLs on the back of their hands referred to the dermatology clinics from March 1 to June 24, 2021. TCA 35% was applied to the back of one hand, and the contralateral hand received Q-switched laser. The interventions were repeated for a total of three sessions 4 weeks apart. Eight weeks after the last treatment session, lesion lightening was graded from 1 to 4. Patient satisfaction with treatment was assessed using a visual analogue scale (VAS). Adverse events were also noted. RESULTS Of the 45 patients included in the current study with a mean age of 52.71 ± 9.73 years, 11 (24.4%) were male. The Fitzpatrick skin type was II in 11 patients (24.4%), III in 23 (51.1%), and IV in 11 (24.4%). Lesion lightening and patient satisfaction were both significantly better with Q-switched laser compared to TCA peeling (standardized mean difference [SMD] = -1.25, 95% confidence interval [CI] -1.69; -0.79, p < 0.001 and SMD = -1.12, 95% CI -1.56; -0.67, p < 0.001, respectively). Overall, post-inflammatory hyperpigmentation (PIH) occurred in one patient in the laser group and for in the TCA group. Also, erythema and pruritus were observed in all patients of both groups after intervention which were treated with topical repair cream. CONCLUSIONS Q-switched laser was superior to TCA peeling for the treatment of SLs in terms of lesion lightening and patient satisfaction with a large effect.

Abstract
BACKGROUND Senile lentigines (SLs) are hyperpigmented macules that predominantly affect the elderly. We aimed to compare the efficacy and safety of hydrogen peroxide35% solution with cryotherapy in the treatment of SLs. PATIENTS AND METHODS This clinical trial included 33 patients with SLs referred to our center. Lesions of each side of the body were randomly allocated to receive 3 sessions of treatment with hydrogen peroxide or cryotherapy at a three-week interval. All patients were followed up 1 week after each round of treatment for the evaluation of side effects, the general effect of the treatment, and the general assessment of response to treatment. RESULTS Thirty-three patients were included in this study with the mean age of 61.79 ± 4.59 years. Average and excellent effects were significantly higher with cryotherapy after the 2nd and 3rd sessions of treatment, respectively. Positive response to treatment was significantly higher with cryotherapy at all time points. Severe erythema was only observed with cryotherapy. Pigmentation was significantly more frequent with cryotherapy than with hydrogen peroxide at any time point (p < 0.001). Also, blisters were only seen with cryotherapy. Moreover, the pain score was significantly higher with cryotherapy at all time points (p < 0.001). Up to one week after the 3rd session of treatment, no recurrence of lesions occurred in any of the groups. CONCLUSIONS Cryotherapy appears to be more efficacious for the treatment of SLs compared to hydrogen peroxide 35% solution; however, hydrogen peroxide seems to have fewer side effects.

Abstract
Cryotherapy (or cryosurgery) has been performed to treat various skin lesions in the field of dermatology; however, to the best of our knowledge, no study has investigated its efficacy and safety for benign pigmented lesions. Therefore, we conducted a split-face study to evaluate the efficacy and safety of cryotherapy in the treatment of benign pigmented lesions. A total of five subjects were included. Picosecond laser therapy was performed to treat the whole face and cryotherapy for half the face. Four weeks after completing the treatment sessions, patients showed more clinical improvement on the laser and cryotherapy combination treatment side than on the laser-only side, with no adverse events. Our study demonstrated that cryotherapy is a potential adjuvant therapeutic modality for benign pigmented lesions.

Abstract
Seborrheic keratosis (SK) is a common benign skin epidermal lesion. Different treatment modalities have been proposed for this lesion. This study aimed to compare the efficacy and safety of electrodesiccation, cryotherapy, CO2 laser, and Er:YAG laser in the treatment of SK. The study was carried out on 30 patients each with four similar facial SKs. Each lesion was assigned to be treated with cryotherapy, electrodesiccation, CO2 laser, and Er:YAG laser in a random fashion. Therapeutic results were evaluated 8 weeks after the interventions through clinical and dermatoscopic assessment. Treatment improvement criteria for each lesion included the texture of the lesion, severity of the pigmentation, and an overall assessment of the healing. The severity of burning, pain, erythema, and the duration of the erythema after the procedures were documented. A survey of the patients' satisfaction with the treatments was also performed. In the assessment of overall lesion healing by two dermatologists, the improvement rate was significantly higher in the CO2, Er:YAG lasers and electrodesiccation group compared to the cryotherapy (p < 0.001). However, the CO2 and Er:YAG laser and the electrodesiccation groups showed no significant difference (p > 0.05). Moreover, no significant difference was observed in posttreatment pigmentation and texture between the groups (p > 0.05). The pain and burning severity after the interventions were negligible in all four groups. Prolonged erythema was not observed in any of the cases; however, the duration of erythema in the Er:YAG laser group was significantly longer (p < 0.001). Patient satisfaction in the cryotherapy group was significantly lower than the other three groups (p < 0.001). The efficacy of treatment and patient satisfaction rate is highly comparable between electrodesiccation, CO2 laser, and Er:YAG laser but significantly higher than cryotherapy.

Abstract
Trichloroacetic acid (TCA) peeling may be effective in solar lentigines, but with concerns regarding potential tumorigenesis. Cryopeeling would be better with improving the whole sun-damaged skin. We aimed to compare the efficacy and safety of cryopeeling and TCA 35% peeling for treatment of solar lentigines and assess their influence on the number of epidermal Langerhans cells (LC). Twenty-five patients were treated with TCA 35% and cryopeeling on the right and left hands, respectively. Two sessions were done 3 weeks apart. Evaluations were scheduled at weeks 0, 3, and 6. Skin biopsies, taken before and after treatment, were evaluated histologically and immunohistochemically for the number of CD1a + epidermal LCs. Lentigines decreased after cryopeeling from the first session (p < .001), but after the second session with TCA peeling (p = .004). Cryopeeling produced significant lightening, compared with TCA (p = .015). Blistering, hyper/hypopigmentation were reported with cryopeeling, whereas only hyperpigmentation was noted after TCA peeling. The LCs remained at about the pretreatment number after cryopeeling (p = .058), though they decreased after TCA (p = .002). Cryopeeling provided faster and superior improvement of lentigines compared with TCA peeling. Furthermore, TCA seems to suppress LCs raising the concern for carcinogenic potential.

Abstract
There are different modalities for hand rejuvenation. Fractional Er:YAG laser and long pulse Nd:YAG laser were introduced for treating hand wrinkles. We plan to compare fractional Er:YAG laser and long pulse Nd:YAG laser in a randomized controlled double-blind design with multiple sessions and larger sample size in comparison with previous studies. Thirty-three participants with hand wrinkles entered this study. They were randomly allocated to undergo three monthly laser treatments on each hand, one with a fractional Er:YAG laser and the other with a long pulse Nd:YAG laser. The evaluations included assessment of clinical improvement determined by two independent dermatologists not enrolled in the treatment along with measuring skin biomechanical property of hands using a sensitive biometrologic device with the assessment of cutaneous resonance running time (CRRT). Moreover, potential side effects and patients' satisfaction have been documented at baseline, 1 month after each treatment, and 3 months after the final treatment session. Clinical evaluation revealed both modalities significantly reduce hand wrinkles (p value < 0.05), with no significant difference between two lasers. Mean CRRT values also decreased significantly after the laser treatment compared to those of the baseline in both laser groups. There was no serious persistent side effect after both laser treatments. Both fractional Er:YAG and long pulse Nd:YAG lasers show substantial clinical improvement of hand skin wrinkles with no serious side effects. However, combination treatment by these lasers along with the other modalities such as fat transfer could lead to better outcomes in hand rejuvenation. TRIAL REGISTRATION IRCT2016032020468N4.

Abstract
As surgical and/or ablative modalities, radiofrequency (RF) has been known to produce good clinical outcomes in dermatology. Recently, 27.12 MHz RF has been introduced and has several advantages over conventional 4 or 6 MHz in terms of the precise ablation and lesser pain perception. We aimed to evaluate the clinical efficacy and safety of 27.12 MHz RF for the treatment of benign cutaneous lesions. Twenty female patient subjects were enrolled. Digital photography and a USB microscope camera were used to monitor the clinical results before one session of treatment with 27.12 MHz RF and after 1 and 3 weeks. Treated lesions included telangiectasias, cherry and spider angiomas, skin tags, seborrheic keratoses, lentigo, milium, dilated pore, acne, piercing hole, and one case of neurofibroma. For vascular lesions, clinical results were excellent for 33.3%, good for 44.4%, moderate for 11.1%, and poor for 11.1%. For nonvascular lesions (epidermal lesions and other benign cutaneous lesions), clinical results were excellent for 48.3%, good for 45.2%, moderate for 3.2%, and poor for 3.2%. No serious adverse events were observed. Mild adverse events reported were slight erythema, scale, and crust. The 27.12 MHz RF treatment of benign vascular and nonvascular lesions appears safe and effective after 3 weeks of follow-up.

Abstract
BACKGROUND AND OBJECTIVE To assess an objective method evaluating the effects of a retinaldehyde-based cream (RA-cream) on solar lentigines; 29 women randomly applied RA-cream on lentigines of one hand and a control cream on the other, once daily for 3 months. METHODS A specific method enabling a reliable visualisation of the lesions was proposed, using high-magnification colour-calibrated camera imaging. Assessment was performed using clinical evaluation by Physician Global Assessment score and image analysis. Luminance determination on the numeric images was performed either on the basis of 5 independent expert's consensus borders or probability map analysis via an algorithm automatically detecting the pigmented area. RESULTS Both image analysis methods showed a similar lightening of ΔL* = 2 after a 3-month treatment by RA-cream, in agreement with single-blind clinical evaluation. CONCLUSION High-magnification colour-calibrated camera imaging combined with probability map analysis is a fast and precise method to follow lentigo depigmentation.

Abstract
Numerous dermatologic conditions may be visualized by the hand surgeon during office hours, including when examining patients for an alternative chief problem. Although the primary focus of the visit may be unrelated to a skin lesion, it is important for the hand surgeon to be familiar with these lesions to address patient inquiries and determine which lesions may require some form of treatment. This article reviews some of the most common benign acquired superficial skin lesions of the hand. Particular attention will be paid to epidermal lesions, pigmented lesions, vascular lesions, dermal fibrous/fibrohistiocytic lesions, and infections that can be confused with skin neoplasms or tumor-like conditions. Diagnostic clues, including photographs, will be provided for each lesion described, as well as the recommended treatment.

Abstract
Background: Although cryotherapy is still the first-line therapy for solar lentigines, because of the side effects such as post-inflammatory hyperpigmentation (PIH), especially in patients with darker skin types, pigment-specific lasers should be considered as a therapy for initial treatment. Aim: The aim of this study is to evaluate the efficacy and safety of cryotherapy compared with 595-nm pulsed dye laser (PDL) with cutaneous compression in the treatment of solar lentigines. Materials and Methods: Twenty-two patients (skin type II–IV) with facial or hand lentigines participated in this study. Lesions of one side of the face or each hand were randomly assigned and treated with either cryotherapy or PDL. Treatments were performed with radiant exposures of 10 J/cm2 , 7-mm spot size and 1.5 ms pulse duration with no epidermal cooling. Photographs were taken before treatment and 1-month later. The response rate and side effects were compared. Results: PDL was more likely to produce substantial lightening of the solar lentigines than cryotherapy, especially in skin type III and IV (n = 8, n = 9; P < 0.05), but might be no difference in type II (n = 5; P > 0.05). PIH was seen only in cryotherapy group. PDL group had only minimal erythema. No purpura was observed. Conclusion: PDL with compression is superior to cryotherapy in the treatment of solar lentigines in darker skin types.
