Tretinoin and retinol are both forms of vitamin A that are commonly used in skincare products. However, they differ in their chemical structures and mechanisms of action.
Tretinoin is a prescription-strength topical medication that is often used to treat acne, as well as to improve the appearance of fine lines, wrinkles, and uneven skin tone. It works by increasing cell turnover and promoting the growth of new skin cells. Tretinoin is also known for its ability to stimulate the production of collagen, which can help improve the overall texture and firmness of the skin.
Retinol, on the other hand, is a form of vitamin A that is available over-the-counter in many skincare products. It is a milder form of vitamin A and is often used to improve the appearance of fine lines, wrinkles, and uneven skin tone. Retinol is converted to retinoic acid (the active form of vitamin A) in the skin, which then acts in a similar way to tretinoin to promote cell turnover and stimulate collagen production. However, because retinol is milder than tretinoin, it may take longer to see results.
