Please see: Please see your dermatologist for evaluation and to discuss treatment options. You should still protect yourself from the sun. Everyone gets sun damage and this causes wrinkles.

Home skincare: You will probably want to consider using a good line of skincare products at home. Get some prescription strength ones from a dermatologist or plastic surgeon. Brands like obagi, pca, vi derm, and so forth.
