Which Acid Removes Hyperpigmentation?
Several acids effectively treat hyperpigmentation, a condition causing dark spots or patches on the skin. The choice of acid depends on the specific type and severity of hyperpigmentation.
- Malic Acid: This acid treats hyperpigmentation conditions like post-inflammatory hyperpigmentation and melasma, along with other skin concerns such as acne and wrinkles. [Source: Reference 1]
- Glycolic Acid: A potent exfoliant, glycolic acid removes dead skin cells, gradually lightening hyperpigmentation, particularly melasma. [Source: Reference 2]
- Azelaic Acid: This dicarboxylic acid reduces inflammation and inhibits melanin production, making it effective in reducing hyperpigmentation. [Source: Reference 4]
- Kojic Acid: A naturally occurring acid, kojic acid is a popular topical treatment for hyperpigmentation. It works by inhibiting melanin production. [Source: References 7 & 8]
- Tranexamic Acid: Often used in more severe cases of melasma, this acid is taken orally and is thought to help reduce hyperpigmentation. [Source: Reference 5]
- Salicylic Acid: This beta-hydroxy acid (BHA) is used in peels to treat post-inflammatory hyperpigmentation. [Source: Reference 6]
- Linoleic and alpha-linolenic acids: These fatty acids lighten UV-induced hyperpigmentation by removing melanin pigment from the epidermis. [Source: Reference 9]
