Sun Protection

We all need protection from ultraviolet radiation.  This is a form of energy produced by the sun which can damage skin cells.  The sun produces two forms of UV radiation which can harm the skin:  UVA and UVB.  UVB is the most dangerous and acute overexposure causes sunburn.  Over longer periods of time (years), cumulative exposure to UVB causes damage to the genetic material in skin cells which can result in the formation of skin cancers.  UVA also plays a role in the formation of skin cancer and is the major cause of the wrinkles, brown spots, and complexion changes that we recognize as aging.

(Tanning beds use mainly UVA; this is a great way to get prematurely aged skin.)

Staying out of the sun, especially in the mid day, minimizes UV damage to the skin, but it is almost impossible to totally avoid exposure.  The small amounts of sun exposure we experience just going to and from work and running errands build up over time and cause most of the cumulative sun damage to our skin.  Broad-brimmed hats can protect the skin from direct sunlight, but remember that 50% of the sun’s rays can be reflected off of cement, sand, or water back onto your face.  Windows and windshields screen only the UVB rays; the UVA rays come right through glass.  Even when temperatures are cool, you can get significant sun exposure.  Clouds are no protection: 80% of the UV rays come right through.

Daily use of sunscreens is an excellent way to protect yourself from harmful UV radiation. There are hundreds of products on the market.  Look for sunscreens with a sun protection factor (SPF) of at least 15 for everyday use.  Products with higher SPF’s are also available.  Many think that the additional protection of an SPF over 30 is minimal, but we feel that the higher protection factor helps make up for deficiencies of application.  All sunscreens are good at blocking UVB, but the only sunscreens that adequately block UVA are those which contain titanium dioxide, zinc oxide, avobenzone (also known as Parasol 1789), or the newest UVA filter, ecamsule (also known as Mexoryl SX).   Remember, it is UVA which causes skin aging, so be sure to use a sunscreen with at least one of these ingredients. Helioplex is a new ingredient that stabilizes avobenzone and extends its protection to 4-5 hours.

There are many sunscreens formulated for the face; these are less likely to feel greasy or clog pores. Many facial sunscreens contain moisturizing ingredients and can be used as an under makeup moisturizer. Sunscreens also come in waterproof formulations which are good for swimming and outdoor activities. Sunscreens should be applied to all exposed areas (face, neck, ears, tops of arms and hands) and ideally should be reapplied every few hours.  Don’t let the ultra high SPF numbers fool you; they still need to be reapplied for maximum efficacy.

There has been some controversy concerning the use of sunscreens and adequate Vitamin D levels.  Vitamin D deficiency is becoming more common and may be related to increased sunscreen use, decreased outdoor activity, and obesity.  It is true that sunshine helps our skin to synthesize Vitamin D; the actual amount of sun needed for adequate levels seems to be in dispute, with some saying 7-10 minutes of exposure to the arms and face once or twice weekly.  We obviously don’t recommend sunbathing but we do  recommend a daily Vitamin D supplement of 800-1200 units daily, especially for those at risk for osteoporosis and for those who have darker skin.  To view the American Academy of Dermatology’s position statement on Vitamin D, click here.
