Glutathione cho Hyperpigmentation

C Bằng chứng Bằng chứng hạn chế từ các nghiên cứu nhỏ, nhưng có một số tín hiệu tích cực.

Multiple small RCTs found oral glutathione (250-1,000 mg/day) may reduce melanin index through tyrosinase inhibition and melanin pathway modulation, primarily studied in Asian populations.
