What does it do?

Hydroquinone is an ingredient used in dermatological pharmaceuticals, primarily for improving excessive pigmentation such as melasma or freckles. This ingredient has a skin-brightening effect by inhibiting the melanin production process.

Hydroquinone inhibits the activity of the enzyme tyrosinase, which is responsible for melanin production, leading to a reduction in melanin synthesis. As a result, skin pigmentation is alleviated and skin tone becomes brighter.
