N-Acetyl Cysteine cho Hyperpigmentation

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

NAC effectively raises intracellular glutathione levels. A controlled trial found NAC (1,200 mg/day) reduced melanin index, potentially through enhanced glutathione-mediated melanin pathway modulation.
