What this trial studies

This study evaluates the safety of a serum containing low doses of alpha hydroxy acids (1% Glycolic acid and Lactic acid) and Polyglutamate acid derivatives for individuals with post-inflammatory hyperpigmentation in Malaysia. Over an 8-week period, participants will undergo skin assessments at baseline, week 4, and week 8 to monitor safety and patient satisfaction. The study aims to determine both the safety of the serum and the satisfaction levels of the participants after using the product.

Who should consider this trial

Good fit: Ideal candidates are Malaysian individuals aged 18 to 40 with post-inflammatory hyperpigmentation.

Not a fit: Patients with known systemic or skin diseases, pregnant or breastfeeding women, and those with a history of certain dermatologic conditions or cosmetic procedures may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a safe and effective treatment option for individuals suffering from post-inflammatory hyperpigmentation.

How similar studies have performed: While similar studies have explored the use of AHAs for skin conditions, the specific combination and focus on safety in this context may be novel.
