                The trade name was originally Retin A, it’s off-patent now, so it comes in many forms. Tretinoin is a vitamin A derivative that does many things in the skin cells and improves the quality of the skin, division or replication, and contours of the anatomy of the skin. Using Tretinoin, along with other molecules we found to be helpful, including an anti-inflammatory and anti-oxidant like topical vitamin C, are good and important parts of the skin care program.

By using the retinol type of products in the evening, along with cleansing and exfoliation, we’re beginning a process of treatment that for most patients will make a substantial impact on their skin quality and appearance.
