Efficacy and Safety of Adapalene Gel and Hyaluronic Acid Versus Adapalene Gel Alone in Mild to Moderate Acne Vulgaris

Acne vulgaris affects around 85% of adolescents and young adults. Adapalene, a topical retinoid, is a common treatment but often causes irritation, leading to poor adherence. Hyaluronic acid (HA), known for its hydrating and anti-inflammatory properties, may help reduce these side effects. This prospective, open-label, randomized controlled trial compares adapalene 0.1% gel combined with HA serum versus adapalene alone over 8 weeks in patients with mild to moderate acne. Key outcomes include acne lesion reduction, incidence and severity of side effects (erythema, dryness, scaling, stinging/burning, pruritus), and skin hydration assessed through the skin turgor test. Acne severity will be measured using the Acne Severity Index (ASI) and Investigator's Global Assessment (IGA) scale. The study anticipates better efficacy, reduced irritation, and improved skin hydration with the combination therapy. Ethical approval was obtained, and informed consent will be secured from all participants.

Phase 3 Study of Denifanstat in Participants With Moderate to Severe Acne (AURORA)

The purpose of this study is to evaluate the safety and efficacy of denifanstat compared with matching placebo in participants with moderate to severe acne vulgaris who are ≥12 years of age. After the 12-week treatment phase, a subset of approximately 530 participants will have the option to consent to an open-label extension phase for an additional 40 weeks of treatment.

Study of New Antiandrogenic Progestogen + Low-dose Estrogen for Moderate Acne Vulgaris

This Phase III randomized, double-blind, placebo-controlled, adaptive, multicenter study evaluates the efficacy and safety of a new concentration of the fixed-dose combination EF190 in women with moderate acne vulgaris over six 28-day treatment cycles. Eligible participants will be randomized (2:1) to receive either the experimental drug or placebo alongside standard skincare. The study includes five in-person visits (screening, randomization, and three follow-ups) and three phone contacts (cycles 2, 4, and 5) to monitor adherence, adverse events, and contraceptive use. A subgroup will undergo additional exploratory assessments, including acne questionnaires, ovarian activity tests, photographic documentation, and specialized lab/ultrasound exams.

Comparison of Topical Clascoterone 1% Cream Versus Adapalene 0.1% Cream in the Treatment of Mild-to-Moderate Acne Vulgaris

This study will compare the effectiveness and safety of topical clascoterone 1% cream and adapalene 0.1% cream in patients with mild-to-moderate acne vulgaris. Acne is a common skin condition that causes blackheads, whiteheads, pimples, and inflammation. A total of 130 eligible participants aged 12-40 years will be enrolled in a randomized controlled trial at the Dermatology Outpatient Department of Pak Emirates Military Hospital, Rawalpindi, Pakistan. Participants will be randomly assigned to one of two treatment groups. Group A will receive clascoterone 1% cream applied twice daily, while Group B will receive adapalene 0.1% cream applied once daily at night. Treatment will continue for 12 weeks. Participants will be assessed at baseline and during follow-up visits at Weeks 4, 8, and 12. Treatment response will be evaluated using the Investigator's Global Assessment (IGA) score and acne lesion counts. Treatment success will be defined as an IGA score of 0 (clear) or 1 (almost clear), with at least a two-grade improvement from baseline at Week 12. Adverse effects, treatment compliance, and patient satisfaction will also be assessed. The study aims to compare the efficacy and tolerability of both treatments in patients with mild-to-moderate acne vulgaris.

study designed to assess the safety, tolerability, and efficacy of IDP-120 Gel and IDP-120 Vehicle Gel

Clascoterone Versus Clindamycin Added to Adapalene/Benzoyl Peroxide for Moderate Facial Acne

This randomised trial compares two treatments added to the same standard acne gel in people with moderate facial acne. All participants will use adapalene 0.1%/benzoyl peroxide 2.5% gel at night. Half will also use clascoterone 1% cream (a non-antibiotic cream that blocks the effect of androgen hormones in the skin), and half will use clindamycin 1% lotion (a topical antibiotic), twice daily for 12 weeks. The main question is whether the reduction in inflamed acne spots (papules and pustules) after 12 weeks differs between the two groups. Secondary questions cover non-inflamed spots, overall clearance, skin irritation, side effects and patient satisfaction. A dermatologist who does not know which treatment each participant receives will count the acne spots at the start and at weeks 4, 8 and 12. Because antibiotic resistance in acne bacteria is increasing, the study will provide local evidence on whether a non-antibiotic option can be used as an alternative partner to standard acne treatment.

Study to Determine Efficacy, Safety, and Tolerability of B244 as a Topical Spray in Subjects With Moderate to Severe Acne Vulgaris

This is a phase 2b, randomized, double-blind, vehicle-controlled clinical trial evaluating the efficacy, safety, and tolerability of B244 compared to vehicle in the treatment of moderate to severe acne vulgaris in adolescents and adults. Participants who meet the study entry criteria will be randomized in a 1:1 ratio to receive twice daily topical doses of B244 O.D. 5.0 or vehicle (control) for 12 weeks.

The Efficacy and Safety of Winona Barrier Special Cream in Post-acne Erythema a Parallel Randomized Controlled Study

The goal of this study is to evaluate the efficacy and safety of winona barrier special cream in post-acne erythema(PAE). The main questions it aims to answer are: whether winona barrier special cream can improve facial skin erythema, transepidermal water loss, water content of stratum corneum, pH,melanin, lipidomic and microbiodemic in patients with PAE . type of study:clinical trial participant population/health conditions The study proposes to recruit 60 PAE patients and 20 healthy individuals The checks of patients were randomly selected to use winona barrier special cream on one side and the Basal Water on the other side. the sampes of surface skin are collected on week0, week4 and week8. Measurements of erythema, transepidermal water loss, stratum corneum water content, pH, and melanin were taken from fixed lesion sites on both cheeks before on week0, week4 and week8. Researchers will compare differences in facial lipidomics and microbiomics between patients' lesion sites and the healthy population, as well as before and after the use of creams by patients to see whether the lipidomics and microbiomics at skin lesions are different in PAE patients compared to the healthy population and whether the intensive care cream has an improved effect on them.

Study to Evaluate the Safety and Efficacy of BF-200 ALA (Ameluz®) and BF-RhodoLED® in the Treatment of Moderate to Severe Acne Vulgaris With Photodynamic Therapy in Adults

The aim of this study is to test the safety and efficacy of photodynamic therapy (PDT) for the medication Ameluz® performed with the PDT-lamp BF-RhodoLED® in comparison to the respective placebo treatment for moderate to severe Acne vulgaris.

Facial Skin Microbiome in Patients With Moderate-to-Severe Acne Vulgaris Treated With Isotretinoin

Acne vulgaris is associated with changes in the facial skin microbiome, but longitudinal microbiome changes during isotretinoin therapy remain incompletely understood. This prospective observational cohort study aims to characterize the facial skin microbiome in patients with moderate-to-severe acne vulgaris before and during isotretinoin treatment and to compare microbiome profiles with healthy individuals. Participants with moderate-to-severe acne vulgaris receiving standard-of-care oral isotretinoin will be followed prospectively. Facial skin swab samples will be collected before treatment and at scheduled follow-up visits during therapy. Healthy volunteers without acne will provide a single facial skin swab for comparison. Bacterial communities will be analyzed using 16S rRNA gene sequencing, and clinical severity will be assessed using validated acne severity scores and lesion counts. The study will evaluate changes in microbial diversity, bacterial composition, and the relative abundance of acne-associated microorganisms during isotretinoin treatment. Associations between microbiome changes and clinical improvement will also be explored. Results are expected to improve understanding of the role of the skin microbiome in acne and provide evidence for future microbiome-based therapeutic strategies.

Clinical Trial to Compare Oral Isotretinoin to Standard of Care in Moderate Acne Skin of Color Patients

In Dermatology, assessment of people of color remains underrepresented in RCTs (\<10%) and guidelines. Acne affects around 9% of the population worldwide and negatively affects quality of life and self-esteem with anxiety, suicidal ideation and physical scarring. Main lesions associate comedons, inflammatory papules and pustules which grading of severity allows decision-making, e.g., topicals in mild acne and isotretinoin in severe acne. In darker skin type patients, i.e., Fitzpatrick phototypes IV-VI, acne-related pigmentation (ARP) occurs in 65% of cases which reflects either per- or post-inflammatory hyperpigmentation. Whatever is the mechanism, ARP (number, size, importance of dyschromia) impacts the quality of life in such patients. In moderate acne, treatment is based on oral antibiotics for 3 months, i.e., doxycycline or lymecycline, with topical treatment like tretinoin targeting comedons (and potentially ARP). However, oral antibiotics first-line were developed in white skin patients only and never showed its efficacy in ARP. Moreover, doxycycline could be associated with new-onset hyperpigmentation in acne patients. Isotretinoin -acting on the sebaceous gland and therefore the most effective drug in acne- is only prescribed after failure of antibiotics according to the guidelines.The main objective: To assess the superiority at M6 of a treatment of moderate facial acne in skin of color patients with oral isotretinoin in first line compared to the current standard of care on the severity of ARP.Multicenter randomized controlled trial - open study. The number of subjects required for the trial = 420

The Impact of Baseline Hormonal Profiles (DHEAS, FSH, LH) on Treatment Response to Systemic Isotretinoin in Adult Female Patients With Acne Vulgaris

Acne vulgaris is a common dermatological condition in adult women, often influenced by hormonal factors. Androgens such as dehydroepiandrosterone sulfate (DHEAS) can stimulate sebaceous gland activity, while gonadotropins (FSH and LH) reflect ovarian and hypothalamic-pituitary axis function. Although systemic isotretinoin is highly effective in severe or treatment-resistant acne, variability in treatment response has been observed among female patients. The role of baseline hormonal levels in predicting isotretinoin response remains unclear. Identifying hormonal predictors of treatment response may improve patient stratification and personalized management. Aim of the study is to evaluate whether baseline serum levels of DHEAS, FSH, and LH are associated with clinical response to systemic isotretinoin in women aged 18 years and older with acne vulgaris.

Randomized Double-blind Study on the Benefit of Spironolactone for Treating Acne of Adult Woman.

Acne vulgaris of adult woman has increased over the past 10 years; it affects currently 20% to 30% of adult women. The physiopathology of adult woman acne is distinguished from the teenager one by essentially 2 factors: * hormonal factor with a peripheral hyperandrogenism coupled with an hypersensibility of cutaneous androgens receptors of these women. But this point is still at the stage of hypothesis. * inflammatory factor linked with Propionibacterium Aces ; indeed these women received most of the time many cures of local and systematic antibiotics at the origin of resistant Propionibacterium Aces strains which lead to a chronical activation of cutaneous innate immunity. On a therapeutic plan, four types of systemic treatment, approved in this indication are: * Tetracyclines which are problematic for the bacterial resistance and consequently constant relapse when they are stopped. * Zinc salts which target only the inflammatory lesions and were shown less effective than cycline * Antiandrogens, with acetate of cyproterone associated with risks of phlebitis and pulmonary embolism, and increase risk of triglycerides, cholesterol and hepatic balance. * The last alternative is represented by isotretinoin but the use in women of childbearing potential is binding because of the teratogen risks and the hyperandrogenism represents an identified risk of relapse. In this context, the spironolactone could represent an interesting alternative. It blocks the 5-alpha-reductase receptors at sebaceous gland and inhibits Luteinizing hormone (LH) production at the pituitary level. It is not submitted to isotretinoin constraints, does not lead to bacterial resistance and targets the peripheral hyperandrogenism. Currently, very few studies have been performed and on a weak number of patients but they showed that at low doses (lower than 200mg/day), spironolactone can be effective against acne. In that context, it seemed clearly interesting to perform the first double-blind randomized study spironolactone vs cyclines which remains the moderate acne reference treatment and to demonstrate the superiority of spironolactone's efficacy in order to establish it as alternative way to cycline.

Effect of Oral Isotretinoin on Ocular Surface and Meibomian Glands

The aim of the study was to evaluate meibomian gland morphology using non-contact meibography and ocular surface changes in patients with acne vulgaris treated with isotretinoin as indicators of dry eye, which is known to be a side effect of isotretinoin.

Clindamycin Phosphate, Adapalene, and Benzoyl Peroxide Triple Combination Gel in Canadian Patients With Acne Vulgaris

The goal of this observational study is to learn about the effects of a treatment that contains clindamycin phosphate, adapalene, and benzoyl peroxide in people with acne. The main questions the study aims to answer are: * How satisfied are people with this treatment? * How well do people follow the treatment plan? * How effective and safe is the treatment? * How does the treatment affect quality of life? * How do people use other skin care products, such as cleansers, moisturizers, and sunscreen, while using this treatment? About 200 people aged 12 and older with acne across Canada will use the treatment as part of their regular care and answer questions about their experience over 20 weeks.

Radiofrequency Treatment Versus Topical Therapy for Facial Acne Vulgaris

This clinical study will compare a radiofrequency (RF) treatment with a standard topical treatment for adults with mild-to-moderate inflammatory facial acne vulgaris. Approximately 60 participants will be randomly assigned to one of two treatment groups. Participants in the RF group will receive three treatment sessions using the Density Noir radiofrequency system at 6-week intervals. Participants in the topical treatment group will use a combination gel containing adapalene 0.1% and benzoyl peroxide 2.5% once daily for 12 weeks. Participants in both groups will be followed for an additional 12 weeks after completion of treatment. The main purpose of the study is to compare how well the two treatments reduce the number of inflammatory acne lesions and facial sebum production. The study will also evaluate treatment safety and tolerability. Additional assessments will include overall acne severity, skin redness, dermal thickness, quality of life, treatment-related pain, participant satisfaction, and durability of treatment response.

Microneedling With Glycolic Acid or Trichloroacetic Acid for Atrophic Acne Scars

Atrophic acne scars are depressed scars that can remain after acne has healed. Microneedling is a procedure that uses very small needles to create controlled micro-injuries in the skin, which may stimulate collagen production and improve scar appearance. Chemical peels, including glycolic acid and trichloroacetic acid, may also improve acne scars. This study compares three approaches for treating atrophic acne scars: microneedling followed by a 35% glycolic acid peel, microneedling followed by a 15% trichloroacetic acid peel, and microneedling alone. Sixty adults with atrophic acne scars are randomly assigned to one of the three groups. Participants receive a series of microneedling treatments at 2-week intervals. The study evaluates changes in scar severity, participant satisfaction, treatment-related pain, recovery time after treatment, and side effects. The findings may help identify whether adding either chemical peel to microneedling provides greater benefit than microneedling alone and whether one combination has a shorter recovery time or fewer side effects.

A Study to Compare the Efficacy, Safety and Pharmacokinetics of Trifarotene 50 mcg/g Cream in Chinese Subjects With Acne Vulgaris

The primary objective is to assess the efficacy of trifarotene 50 microgram per gram (mcg/g) cream versus vehicle cream when applied once daily (QD) for 12 weeks in Chinese participants with moderate facial and truncal acne vulgaris.

Adjunctive 308-nm Excimer Light With Oral Azithromycin for Inflammatory Acne

This randomized, evaluator-blinded, split-face study evaluated whether adjunctive lesion-directed 308-nm excimer light improves inflammatory acne outcomes during oral azithromycin therapy. All participants received oral azithromycin 500 mg three times weekly for 8 weeks. One randomly allocated hemiface additionally received 308-nm excimer light twice weekly for 8 weeks, while the contralateral hemiface served as the azithromycin-only control. Papule and pustule counts and hemiface Investigator's Global Assessment were assessed through Week 8. Investigator's Global Assessment was reassessed at Week 16 after an 8-week treatment-free follow-up. We hypothesized that the excimer-treated hemiface would demonstrate greater reduction in total inflammatory-lesion count by Week 8.
