A good skin care routine is essential to perfecting your skin at any age and to defend it against aging. There are several products available, both prescription and nonprescription, that can curb aging and even reverse some of the damage, including photodamage. Some of these include Retin A, Glycolic acids, and topical antioxidants, especially vitamins C and E. These treatments may be combined with other therapies to increase effectiveness. Topicals also offer preventive value, and can reduce the need to repeat procedures or increase the time between them.
