Tretinoin (Retino-A) is also really good for improving the skin. It's over-the-counter and inexpensive. It's a dermatologist's secret. Minor frown lines started showing up on my face early this year, and after a few applications they have nearly disappeared.

The one downside of the treatment is that it makes your skin more susceptible to sun damage-- mainly because it increases cellular turnover rate-- so you have to wear sunscreen every day.
