June 1, 2009 -- Question: What is tretinoin cream, how does it work, and how effective is it in treating aging skin?
Answer: Tretinoin cream is a common prescription given by dermatologists. Tretinoin is a vitamin A derivative. It works by two things: Firstly it increases the cell/skin turnover rate, and secondly, is boosts collagen synthesis. Because of these things it has many uses in dermatology. It helps improve the appearance of fine wrinkles, it helps eliminate dispigmentation, or color differences in the skin.
It also helps to eliminate roughness and make your skin more smooth. Tretinoin is only available by prescription. If you feel that you would like to talk more about tretinoin, please consult your local dermatologist.
