Photoaging Prevention and Topical Treatments

A rapidly increasing number of people visit dermatologists for the prevention and treatment of aging skin. Sun avoidance and sunscreen use are widely accepted strategies of primary prevention against photoaging. Convincing evidence shows that topical application of retinoids has an effect on reversing, at least partially, mild to moderate photodamage. Antioxidants and alpha-hydroxy acids can alter the skin structure and function. Enzymes that repair DNA damage or oligonucleotides that enhance the endogenous capacity for DNA damage repair may prove to be future preventive/therapeutic interventions for aging skin.
