Detailed answer

Hydroquinone is a skin-lightening agent that can be effective in fading acne scars. It works by inhibiting the production of melanin, which is responsible for darkening the skin. To use hydroquinone, start by cleansing your face and applying a thin layer of the cream or gel onto the scarred areas. Use it once or twice daily, as directed by your dermatologist. It's important to note that hydroquinone should be used for a limited period of time, typically not exceeding 3-6 months, as long-term use may lead to unwanted side effects. Additionally, always follow the instructions and recommendations of your dermatologist, and remember to wear sunscreen daily as hydroquinone can increase sun sensitivity. It's also important to have realistic expectations, as hydroquinone may not completely eliminate acne scars, but it can certainly help in fading and reducing their appearance.
