Skin‐Lightening Efficacy of Leatherleaf Fern Extract and a Leatherleaf Fern‐Based Facial Serum In Vitro and Clinical Trial
Abstract
Hyperpigmentation, caused by excessive melanin accumulation, is a significant cosmetic concern in dermatology. Natural compounds are receiving attention as safe and effective skin‐lightening agents due to their antioxidant properties and ability to inhibit melanin synthesis.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
