Background: The SkinMedica Acne Treatment Platform (SM Regimen) was formulated to treat acne without overdrying the skin. We evaluated efficacy and tolerability of the SM Regimen (including a novel 1% salicylic acid Acne Clarifying Cleanser and 2% salicylic acid Acne Treatment Lotion) versus a prescription formulation (Rx Regimen; including adapalene 0.1%/benzoyl peroxide 2.5%) in a diverse population of adults with mild to moderate facial acne., Methods: This single-center, double-blind, randomized study enrolled adults (18-45 years) with Fitzpatrick skin types (FST) I-VI. SM Regimen or Rx Regimen was applied topically to the entire face for 12 weeks. Assessments were conducted at 24 and 48 h and 4, 8, and 12 weeks., Results: Subjects (SM Regimen, n = 31; Rx Regimen, n = 23) were primarily female (90.7%) with mean age of 28.6 years; 53.8% had FST IV-VI. Efficacy was comparable between regimens. The SM regimen resulted in significant improvements versus baseline in mean Investigator's Global Assessment of acne severity from 48 h through week 12 (p ≤ 0.001), as well as significant and sustained improvements from baseline in total acne lesion count, global postinflammatory hyperpigmentation/postinflammatory erythema, and oiliness. The SM Regimen was well tolerated at all time points, with mean scores below mild for all parameters; the Rx Regimen caused significantly more tightness/dry feeling at week 4 versus SM Regimen (p = 0.008). Subjects (> 96%) reported high satisfaction with the SM Regimen at all time points., Conclusions: The SM Regimen reduced acne severity and skin oiliness, evening out skin tone without overdrying or irritating the skin., (© 2024 The Author(s).

Objective: Salicylic acid (SA) has been used for treatment of acne of different severity levels. However, there are few researches about the safety and efficacy for treatment of mild to moderate acne, and the improvement of the skin condition by using 2% supramolecular salicylic acid (SSA) compared to Davuwen Adapaline gel., Methods: A multicenter, randomized, assessor-blind and parallel-controlled study was conducted. A total of 500 patients (trial group: 249, control group: 251) with mild to moderate (grade I-II) facial acne vulgaris were recruited in this study over a 16-week trial period. Patients in the trial group were treated with Broda 2% SSA hydrogel, while control group treated with Davuwen Adapaline gel once a day. The number of inflammatory papules, comedones, and pustules were counted and the rate of lesion reduction was calculated pre- and post-treatment. Then, the skin physiological indicators, including L*a*b*, TEWL, skin sebum and hydration were measured. Statistical analysis was conducted using SAS 9.4. Significance was set at p = 0.05., Results: At the end of 12 weeks' therapy, the regression and markedly improvement rate of the trail group and the control group were 51.01% and 43.10% respectively, and there was no significant difference in the improvement rate between two groups (p = 0.0831). Although, there was no difference in adverse events rate between two groups, the adverse events rate of the trail group was 0.40%, a little lower than the control group (0.80%). Moreover, there was a significant difference in the numbers of pores at T1 between two groups., Conclusion: Both 2% SSA and Adapaline gel were equally effective in the treatment of mild to moderate acne vulgaris. 2% SSA is worth the clinical promotion and application in mild to moderate acne vulgaris., (© 2024 The Authors.

Objective: To observe the efficacy and safety of supramolecular salicylic acid monotherapy and supramolecular nicotinamide in the treatment of chloasma., Methods: A total of 28 female patients with chloasma diagnosed in the dermatology outpatient department of our hospital were randomly divided into an experimental group and a control group, with 14 cases in each group. All patients were treated with 30% supramolecular salicylic acid every 2 weeks, for a total of 8 treatments. The experimental group was treated with 10% supramolecular nicotinamide once in the morning and once in the evening, and the control group was a blank control. Before each exfoliation treatment, subjects were photographed with a VISIA skin detector, and skin image analysis and modified melasma area and severity index (MASI) score were performed., Results: According to the MMASI decrease rate (%) before and after treatment, the effective rate of the experimental group was 64.29%, and the effective rate of the control group was 14.29%. The results of the GriffithS10 and VISIA were improved. During the whole treatment, there was one mild adverse reaction in both groups., Conclusion: Salicylic acid stripping combined with nicotinamide in the treatment of chloasma is safe and effective, can improve skin conditions, and can be widely applied in clinical practice., (© 2023 The Authors.

Background: Inflammatory and non-inflammatory acne lesions constitute a significant clinical challenge in acne subjects., Aim: To evaluate the efficacy and safety of a facial serum and a mask containing salicylic acid and lipohydroxy acid for improving skin conditions., Methods: This randomized controlled trial included adults with comedones, post-inflammatory erythema (PIE) and/or hyperpigmentation (PIH) in Shanghai, China in July 2021. Participants were randomly assigned 1:1 to receive the study Serum + Mask or serum alone for 8 weeks. Acne severity, comedones, papules, pustules, PIE, PIH, skin pores, skin tone evenness, sebum secretion, skin hydration, and trans-epidermal water loss were evaluated at T0d, T1d, T7d, T14d, T28d, and T56d., Results: Eighty-three participants were included, including 41 and 42 in the Serum + Mask and Serum groups, respectively. Acne severity, density of skin pores, skin tone evenness, PIH foci on face, PIE foci on nose, intensity of PIE and PIH, closed comedones on face, open comedones on nose, sebum secretion, and skin hydration were significantly improved from baseline after 8 weeks of treatment in both groups (all p < 0.05). Addition of the mask improved the number of closed comedones (-6.56 ± 0.39 vs. -5.19 ± 0.44, p = 0.022) and acne severity (-0.39 ± 0.08 vs. -0.12 ± 0.09, p = 0.026) substantially more than using the serum alone. No adverse reaction was reported in either group., Conclusions: The study serum improved skin conditions by regulating skin barrier function and achieving a balance of skin hydration and sebum secretion, removing comedones and improving PIE and PIH. Addition of the mask accelerated the effects without compromising safety., (© 2023 L'Oreal. Journal of Cosmetic Dermatology published by Wiley Periodicals LLC.)

Background: Acne tarda (AT) is typically known as adult acne and most preferably affected 25-45 age groups. Used isotretinoid monotherapy is not effective and also produces side effects from long treatment., Aim: The present study assesses the effectiveness of combined treatment of oral isotretinoid with topical chemical peeling (20% salicylic and 10% mandelic acid known as SM peeling) by a comparative double-blind randomized single-center interventional open-label study., Materials and Methods: A total fifty-eight participants AT outpatients (25-45 age groups) attending for diagnosis in two groups and effectiveness of proposed combined treatments were determined at baseline and follow-up within 4-week interval. Briefly group A (n = 28) received 0.5 mg/kg of oral isotretinoin once daily for 16 weeks and group B (n = 30) received the same oral dose, addition with SM peeling every 4 weeks interval for 16 weeks. After 4 weeks, treatment efficacy was assessed based on Michelson's acne severity index (MASI) and visual analog scale (VAS), further validated using statistical tools., Results: Based on MASI and VAS scores, combined treatment was significantly effective than the monotherapy. The pre- and post-treatment analyses of response to scarring, inflammatory components at baseline and at the end of treatment were also statistically significant with p > 0.008., Conclusion: The above investigation revealed that the combination of oral isotretinoin with SM peeling was highly effective and could be used as newer therapy against AT without any serious side effects., (© 2022 Wiley Periodicals LLC.)

Background: Acne vulgaris (AV) is a common dermatosis. For moderate to severe AV, isotretinoin is the first-line treatment. Chemical peeling with supramolecular salicylic acid (SSA) was developed with water solubility and advanced skin penetration properties. In the present study, we investigated the efficacy and safety of oral low-dose isotretinoin combined with 30% SSA chemical peeling., Methods: Thirty-three moderate-to-severe acne patients were enrolled and received oral low-dose (0.2-0.4 mg/kg/d) isotretinoin and were then randomly assigned to receive 30% SSA or not on each side of the face with 2-week intervals for four sessions. Photos, the number of lesions, GAGS score, skin indices (melanin, erythema, pore, and texture), hydration, and transepidermal water loss (TEWL) were assessed at 0, 2, 4, 6, and 10 weeks. Side effects, efficacy, and satisfactory rates were recorded., Results: A total of 29 patients completed the study. Oral isotretinoin combined with SSA decreased response time compared to isotretinoin monotherapy, with significantly improved GAGS score, count of lesions, and efficacy (%) at 4-6 weeks. Skin indices of melanin, erythema, pore, and texture evaluated at week 10 were improved as well. Oral isotretinoin with or without SSA was effective by the lesion clearance; only SSA significantly improved the TEWL. All the side effects were temporary and tolerable, and no adverse effects were observed., Conclusion: Oral low-dose isotretinoin combined with 30% SSA is safe and effective, which advanced the onset of action and improves lesion clearance., (© 2022 the International Society of Dermatology.)

Objective: Antibiotics and retinoids have been used for acne vulgaris for decades. Though effective, each has its own drawbacks. Chemical peels have been used for treatment of acne vulgaris with inadequate clinical evidence. We sought to determine the efficacy and safety of Jessner's solution (JS) in comparison with salicylic acid (SA) 30% in the management of acne vulgaris and postacne hyperpigmentation in patients with colored skin., Methods: A total of 36 subjects (94.5% Fitzpatick Type IV-V) were recruited in this randomized double-blinded, split-face, controlled trial. Each side of the face was randomly assigned for treatment with either JS or SA. Subjects were treated once fortnightly for a total of three sessions. Lesion counting, Michaelsson acne score (MAS), photographs, and postacne hyperpigmentation index (PAHPI) were used to objectively assess the improvement. Complications were assessed during each visit. Statistical analysis was conducted using SPSS v22.0. Significance was set at P = 0.05., Results: At the end of therapy, significant reduction in inflammatory, noninflammatory lesions, MAS, and PAHPI scores (P < 0.001, respectively) were noted in comparison to baseline. Mixed model analysis revealed no significant outcome difference between the two groups. Patients who reported good and very good outcome were 76.4% (JS) and 85.3% (SA). Burning, stinging sensation, and exfoliation were the common complications reported. Postinflammatory hyperpigmentation was reported only once in the JS arm., Conclusion: Both JS and SA were equally effective in the treatment of acne vulgaris and reducing postacne hyperpigmentation in patients with colored skin., (© 2020 the International Society of Dermatology.)

Background: Riehl's melanosis is a chronic, refractory disorder, which can adversely affect patient's quality of life. Intense pulse light, neodymium-doped yttrium aluminum garnet laser, hydroquinone, tranexamic acid have been reported to treat this disease, but there have been few reports on the effectiveness of other treatments., Aim: To assess the efficacy and safety of triple combination therapy with salicylic acid chemical peels, oral glycyrrhizin compound, and vitamin C for Riehl's melanosis., Patients/methods: Three patients diagnosed with Riehl's melanosis were enrolled. All patients were treated with glycyrrhizin compound (150 mg/d), vitamin C (100 mg/d), and salicylic acid 30% peels once every 2 weeks. Clinical photographs and VISIA were used to assess the efficacy., Results: All patients received obvious improvement and reported no obvious side effects., Conclusion: Triple combination therapy with salicylic acid peels, oral glycyrrhizin compound, and vitamin C is a safe and effective modality for Riehl's melanosis., (© 2019 Wiley Periodicals, Inc.)

Background: Glycolic acid (GA) and salicylic acid (SA) peels have been used separately for acne treatment, not as a sequential peel., Aim: To evaluate the efficacy and safety of sequential peeling with 70% GA and 20% SA as a monotherapy and as an adjuvant to systemic doxycycline in treatment of mild to moderate acne and the effect on serum interleukin (IL) 17 and tissue IL-1α., Patients/methods: Forty-five mild to moderate acne vulgaris patients were randomly assigned into three groups. Group [A] underwent sequential application of 70% GA followed by 20% SA biweekly for three months. Group [B] underwent sequential peeling and doxycycline PO100 mg BD for 1 month followed by 100 OD for 2 months. Group [C] received oral doxycycline. Acne grading, lesion counting, and patient satisfaction were assessed. Serum samples and perilesional skin biopsies were obtained at onset and 2 weeks after finishing the treatment for assessment of serum IL-17 and tissue IL-1α., Results: All groups showed statistically significant decrease in acne grading and lesion count, increase in patient satisfaction, and decrease in serum IL-17 and tissue IL-1 α after treatment. There was no significant difference between the 3 groups before or after treatment, except regarding patient satisfaction after treatment, which was significantly higher in groups [A] and [B] than group [C] (P = .001)., Conclusions: This study recommends using sequential GA 70% and SA 20% peels in the treatment of mild or moderate acne vulgaris as a new cost-effective mode, with low-down time and potential safety, in noncompliant patients on medical therapy., (© 2019 Wiley Periodicals, Inc.)

Background: Chemical peels have become a popular modality in the treatment of acne vulgaris (AV). Mandelic acid (MA) is a new emerging peeling agent for AV owing to its antibacterial and anti-inflammatory properties. Hence, it is worthwhile to evaluate the effectiveness and safety profile of this newer agent and to compare it with an older established peeling agent, salicylic acid (SA) in the treatment of AV., Objective: Comparison between therapeutic efficacy and safety of 45% MA peel with 30% SA peel in Indian patients suffering from mild-to-moderate facial AV., Methods: A total of 50 patients suffering from mild-to-moderate AV were randomly divided into two groups, with one receiving 30% SA peels and the other receiving 45% MA peels at an interval of 2 weeks for six sessions. Total duration of the study was 12 weeks. Michaelsson acne scores (MAS) and clinical photographs were used to evaluate the efficacy of therapy objectively. Adverse effects of both the agents were also noted at each visit., Results: Both agents showed almost equal efficacy in improving mild-to-moderate AV. Salicylic acid was found better in treating noninflammatory lesions, while MA had an upper hand in treating inflammatory lesions. Overall, there was no significant difference between the two peels in improving MAS and percentage decrease in MAS. However, adverse effects were lesser with MA peels., Conclusion: About 45% MA peel was found to be equally effective as 30% SA peel in mild-to-moderate facial AV. However, safety and tolerability of MA peel were better than SA peel., (© 2019 Wiley Periodicals, Inc.)

Background: Melasma is an acquired hyperpigmentation, often involving the face, and a source of distress for the affected individuals. Although treatment is challenging and frequently a multimodality approach, topical applications are the mainstay of therapy., Objective: Due to the frequent relapses, a therapy both acting rapidly and suitable for long-term use, with fewer adverse effects should be administered. In our outpatient clinic, we treated the melasma patients with a previously unreported triple combination which was empirically formulated with lesser amount of active components, regarding the balance between long-term use and safety., Methods: Sixty-eight female patients with melasma who referred to our hospital dermatology clinic in the years 2016-2017 were retrospectively recruited. They all had completed 6-month treatment with a prescribed cream mixture comprised of azelaic acid (4%), hydroquinone (1.6%), methylprednisolone aceponate (0.04%), and salicylic acid (2%). The outcomes were evaluated both instrumentally (Melanin Index/MI) and by patients (Patient Self-Assessment Scale/PSAS)., Results: Adverse effects declared by the patients were transient irritation in three and mild hypertrichosis in two. Both the MI and PSAS values were found extremely significant at the end of 6th month, compared with initial values. Approximately 62% of total decrease in MI was realized in the first 3 months., Conclusion: The triple combination containing active ingredients with lesser concentrations than proposed, and with the addition of 2% salicylic acid, may be promising as a quite effective and safe protocol in treatment of melasma for longer durations., (© 2019 Wiley Periodicals, Inc.)

Introduction: Chemical peeling is a well-identified therapeutic modality for acne vulgaris (AV). Jessner's solution (JS) is a known peeling agent for acne since more than 100 years. Salicylic acid (SA) peel is a well-established peeling agent for acne. There is paucity of literature comparing the current peeling agents of choice, that is, SA with the older peeling agents, that is, JS for acne., Objective: To compare the efficacy and safety of 30% SA vs. JS peels in treatment of mild-to-moderate facial acne in Indian patients., Materials and Method: A total of 40 patients with mild-to-moderate AV were enrolled for 12 weeks and were randomly divided into two groups: group 1, 30% SA peels and group 2, JS peels were performed 2 weeks apart with total of six peels in 12-week duration. Clinical improvement was assessed objectively using Michaelsson acne scores (MAS) and clinical photographs. Side effects were observed at each visit., Results: At the end of therapy, improvement in MAS and percentage decrease in MAS were significantly higher in group 1 as compared to group 2. Likewise, decrease in mean comedone counts in group 1 was significantly higher as compared to group 2. However, there was no statistically significant difference in the decrease in mean papule and pustule counts between the two groups. Both the groups tolerated the peels well., Conclusion: Thus, 30% SA peels were more effective than JS peels in treatment of noninflammatory lesions, that is, comedones and in overall improvement of mild-to-moderate facial acne vulgaris., (© 2016 Wiley Periodicals, Inc.)

Background: Postinflammatory hyperpigmentation (PIH) is an acquired hyperpigmentation that involves areas of prior cutaneous inflammation. In addition to prevention, there are a variety of medications and procedures used to treat PIH., Aim of the Work: The aim of this work was to evaluate the efficacy, tolerability, and safety of salicylic acid peeling in comparison with topical tretinoin in the treatment of PIH., Patients and Methods: This study included forty-five patients with PIH lesions. The patients were divided into three groups, group I was treated with salicylic acid peeling 20-30%, group II was treated with topical tretinoin 0.1%, and group III was treated with combination of salicylic acid peel and topical tretinoin. The patients were assessed clinically to evaluate the efficacy, tolerability, and safety of the treatment. Dermoscopy was carried out to the recurrent or nonimproved cases only., Results: Combination of salicylic acid peel and topical tretinoin treatment showed significant clinical improvement of PIH than each treatment alone with no complications. There was no significant difference in the recurrence rate between the three groups. There was nonsignificant difference between the efficacy of the treatment and the PIH type in the studied groups. There was nonsignificant difference between the efficacy of the treatment and the duration of the PIH except for group III., Conclusion: Combination treatment modality is believed to be preferred in the treatment of PIH due to its higher efficacy than single treatment alone, with well tolerability, less side effects, and low recurrence rate., (© 2016 Wiley Periodicals, Inc.)

Background: Lipohydroxyacid is a lipophilic derivative of salicylic acid with comedolytic properties., Objectives: To compare lipohydroxyacid and salicylic acid peels in subjects with comedonal acne., Methods: In this split face, randomized study, 20 subjects with comedonal acne received lipohydroxyacid peels on one side of the face, while the other side was treated with salicylic acid peels. A total of six peels at 2-week intervals were performed. Efficacy was evaluated by counting noninflammatory and inflammatory lesions and by performing a global change in acne assessment. Safety was assessed by evaluating adverse events, global tolerance, and the presence of erythema, scaling, and dryness., Results: There was a statistically significant decrease of 55.6% and 48.5% from baseline to Day 98 in the mean number of noninflammatory lesions for the sides treated with lipohydroxyacid and salicylic acid peels, respectively (P < 0.001). There was no significant difference in the degree of reduction in noninflammatory lesions between the two peels. There was no significant reduction in the number of inflammatory lesions. Both peels were generally very well tolerated., Conclusion: This study suggests that lipohydroxyacid peels can be beneficial to subjects with comedonal acne., (© 2011 Wiley Periodicals, Inc.)
