Retinol is a form of vitamin A that was created to offer an over-the-counter alternative to prescription retinoic acid (Retin-A or Renova). It is milder than Renova and its effect is more subtle, but this makes it a good choice for people with somewhat sensitive skin. Retinol is supported by before-and-after studies showing that it diminishes fine wrinkles, evens out the color of the skin, and helps repair sun damage.
