Hydroquinone: Uses, Side Effects, and Precautions

Hydroquinone is a skin-lightening agent that bleaches the skin, helping to treat various forms of hyperpigmentation. By decreasing the number of melanocytes, it reduces melanin production, which affects skin tone. Hydroquinone is available in cream, gel, lotion, and emulsion forms.

Hydroquinone Uses

Hydroquinone is used to treat skin conditions related to hyperpigmentation, including:

Acne scars
Age spots
Freckles
Melasma
Post-inflammatory marks from psoriasis and eczema

It helps fade red or brown spots but does not affect active inflammation. The cream can minimize acne scarring but won't reduce redness from active breakouts.
