Several acids are used to treat hyperpigmentation, which is a condition causing darker patches of skin due to excess melanin production. These acids work by exfoliating the skin, removing the superficial layer containing excess pigment, or inhibiting melanin production.
Effective Acids for Pigmentation Removal:

Glycolic Acid: A potent alpha hydroxy acid (AHA) derived from sugarcane. It's known for its exfoliating properties, effectively removing dead skin cells and improving skin tone. It's commonly used to treat melasma. [Source: Dear Brightly, Medical News Today, Miiskin]

How these acids work: These acids primarily work by exfoliating the skin, removing the outer layer of dead skin cells that may contain excess melanin. This process reveals brighter, more even-toned skin underneath. Some, like Kojic acid, also have properties that inhibit melanin production directly.
Important Note: It's crucial to consult a dermatologist before using any acid for hyperpigmentation treatment. They can assess your skin type, condition, and recommend the appropriate concentration and application method to avoid skin irritation or damage. The effectiveness of these acids varies from person to person.
