Photodamaged or sun damaged skin occurs with exposure to sunlight (UVA or UVB). It happens whether or not we deliberately suntan. Photodamage, rather than the normal aging process, has been shown to account for around 90 percent of cosmetic skin problems associated with age. Photodamage to skin shows up in various ways. SF Bay Cosmetic Surgery Medical Group offers patients non-invasive treatments that can help lessen sun damage, as well as improve the texture and tone of your skin.
