Tretinoin works by increasing cell turnover and promoting collagen production in the skin, which can help to reduce the appearance of fine lines, wrinkles, and acne. It can also help to even out skin tone and texture, and improve the overall health and appearance of the skin.

Tretinoin is typically recommended for people with acne-prone or aging skin. It is also commonly used as a treatment for photoaging, which is damage to the skin caused by prolonged exposure to UV radiation.

Tretinoin can be used on all skin types, but it is important to talk to a dermatologist before starting treatment as it may cause skin irritation and increase sun sensitivity.

To use tretinoin in your skincare routine, it is recommended to start by using it once or twice a week, at night after cleansing the skin. Gradually increase the frequency of use as your skin becomes accustomed to the product. It is important to use sunscreen during the day, as tretinoin can increase sensitivity to UV radiation. It is also important to use a moisturizer and avoid other exfoliating products while using tretinoin.
