Detailed answer

Hydroquinone is a topical skin-lightening agent that suppresses hyperpigmentation by inhibiting the enzyme responsible for melanin production. It is commonly used in the treatment of melasma, a condition characterized by brown or gray patches on the skin. Hydroquinone works by decreasing the production of melanin in the affected areas, leading to a reduction in the appearance of dark patches. It is typically applied once or twice daily as directed by a skincare professional, and it is often used in combination with other ingredients such as retinoids or corticosteroids for optimal results. However, it is important to use hydroquinone as directed and under the supervision of a healthcare professional, as prolonged or excessive use may lead to skin irritation or other side effects.
