Detailed answer

Hydroquinone is a skin-lightening agent that works by inhibiting the activity of tyrosinase, an enzyme involved in melanin production. Melanin is responsible for pigmentation in the skin, and excessive production can lead to the formation of dark spots. By reducing melanin production, hydroquinone helps to fade hyperpigmentation and even out skin tone. It also has antioxidant properties that help protect the skin against damage caused by free radicals. Hydroquinone is typically used in topical creams and serums, and its effectiveness may vary depending on the concentration and regularity of use. It is recommended to use hydroquinone products under the guidance of a skincare professional.
