Birthday aging or environmental sun damage

Most clients will have birthday aging and sun damage. The severity will vary based on the amount of sun exposure they have experienced. Everyone over the age of 30 years old will have some form of aging, primarily expression lines. These first appear in the outer eye areas and forehead, and eventually lead to the folds around the nasalabial folds. The age at which sun damage appears depends on the Fitzpatrick scale for skin types, and the amount of sun exposure that the client has endured. 
By avoidance of sun and daily use of sunscreen, you can help ward off the daily appearance of aging skin.
As a skin specialist, it is imperative that I educate my client about the devastating effects of sun on skin. It should be stressed that damage is cumulative, like termites destroying a house.
Antioxidants such as Vitamin C, E, A and plant cells are ingredients that have to be formulated for every different type of skin depending on sensitivity. We also have age management  performance ingredients in high tech serums and moisturizers that help maintain a plentiful amount of moisture and lipids in the epidermis. Cell turnover is greatly enhanced by AHAs to make the surface appear younger and translucent, and they also trigger production of moisture binding lipids that help support a younger looking appearance of smoother, firmer skin and a healthy glow.
Home care is essential as well as regular hydrating facials and microdermabrasion treatments. Using proper cleansing products as well as serums and moisturizers will help combat the birthday or aging skin.
