Acretin 0.025% Cream contains the active ingredient Tretinoin, which is a form of Vitamin A. It is commonly used to treat acne and other skin conditions, such as fine wrinkles and hyperpigmentation. Tretinoin works by promoting the turnover of skin cells, helping to prevent clogged pores, reduce acne lesions, and improve the appearance of the skin. It also helps in stimulating collagen production, which can improve skin texture and reduce fine lines. Acretin cream is typically applied to the affected area once daily, preferably at night, as directed by a healthcare provider. It is important to use sunscreen during the day, as Tretinoin can make the skin more sensitive to sunlight.
