Comparative Evaluation of Topical 30% Metformin and Kligman's Regimen in Women With Melasma

It's a prospective, randomised, assessor-blinded clinical study comparing topical 30% metformin with Kligman's regimen for melasma in women aged 35-55 years at Fauji Foundation Hospital, Rawalpindi. The study seeks to ascertain which treatment yields a more significant decrease in the modified MASI score over an 8-week period and which treatment is associated with fewer adverse effects, such as erythema, burning, peeling, and post-inflammatory hyperpigmentation. A total of 82 participants will be enrolled and randomly assigned to either metformin cream or Kligman's regimen, with both groups also using sunscreen. Assessments will be done at baseline, week 4, and week 8 through mMASI scoring, photographs, and side-effect monitoring. Data will be analyzed in SPSS 26 using t-tests and chi-square testing. The study is based on evidence suggesting metformin may offer comparable efficacy with better tolerability.

Expert Consensus on the Clinical Management of Melasma: A Delphi Method Study

This study aims to gather expert opinions on the best ways to treat and manage melasma, a common skin condition characterized by dark patches on the face. Using a method called the Delphi Method, a group of dermatologists and other specialists will participate in several rounds of surveys to share their insights and reach a consensus on the most effective treatments and management strategies. The goal is to create a set of evidence-based guidelines that can help doctors provide more consistent, effective care for patients with melasma. The study will ensure that all experts' opinions are anonymous, and the results will be shared to improve treatment practices worldwide.

Ultrasound-Enhanced Delivery of Compound TXA Solution in Melasma

Melasma is a localized, acquired hyperpigmentary skin disorder characterized by well-defined, light to dark brown patches. Based on clinical practice and extensive literature reports, tranexamic acid and reduced Glutathione (GSH) are both applied in the treatment of melasma, but their water-soluble nature presents challenges for transdermal absorption. Our preliminary basic and clinical research has demonstrated that ultrasound-assisted delivery significantly enhances the absorption of tranexamic acid and other water-soluble components. Its effect on the skin barrier is temporary and reversible. This study aims to evaluate the efficacy and safety of a compound solution (10% tranexamic acid, 2% GSH) delivered via ultrasound for melasma treatment through a split-face controlled trial.

Oral Melatonin Versus Oral Tranexamic Acid in the Management of Melasma

This study will compare the efficacy of oral melatonin and oral tranexamic acid in treating melasma, with the aim of determining whether melatonin is more effective than tranexamic acid, as measured by MASI scores. Literature suggests melatonin may be more effective due to its antioxidant, anti-inflammatory, and anti-melanogenic properties. The findings will assess whether melatonin provides better efficacy and tolerance compared to tranexamic acid in managing this persistent condition. Efficacy will be assessed by comparing the baseline MASI scores with the scores obtained at six-week and twelve-week follow-up points based on the following cut-offs: \<25% improvement Mild response 25-50% improvement Moderate Response 51-75% improvement Good response \>75% improvement Excellent Response

COMPARISON OF A COSMETIC SERUM AND 4% HYDROQUINONE FOR TREATING MELASMA OVER 84 DAYS

The goal of this clinical trial is to compare the dermatological tolerance and skin-lightening efficacy of a cosmetic depigmenting serum to a 4% hydroquinone-based product in adult male and female subjects aged 18-65 years with mild to moderate epidermal or mixed-type melasma. The main questions it aims to answer are: Does the cosmetic serum reduce the severity of melasma (measured by mMASI) after 84 days of use? Is the cosmetic serum better tolerated than 4% hydroquinone under real-use conditions? Researchers will compare the serum group and the hydroquinone group to determine whether the cosmetic product achieves comparable pigmentation improvement with superior skin tolerability. Participants will: Group 1: Apply a morning routine (Depiwhite Serum + Depiwhite M SPF50+ cream) Apply an evening routine (Depiwhite Serum + Placebo Cream without Hydroquinone) Group 2: Apply a morning routine (Serum Placebo + Depiwhite M SPF50+ cream) Apply an evening routine (Serum Placebo + Depigmenting Cream with hydroquinone 4%) Visit the clinical site at baseline (Day 0), Day 56, and Day 84 for assessments Complete standardized photographs, self-assessment questionnaires, and quality-of-life surveys (MELASQoL and ASLQI) Undergo clinical evaluations by a dermatologist, including mMASI scoring and tolerance assessment
