Here comes the sun! Although sunscreen is a year round necessity, more sun exposure occurs during the longer, warmer days. Sunscreen works to prevent the harmful ultraviolet A (UVA) and ultraviolet B (UVB) rays of the sun from injuring the skin and causing long term damage which leads to wrinkles, dark spots, loss of elasticity and in some, skin cancer. Here are a few things to think about:
-SPF is not additive. Having two products with SPF 15 will not equal SPF 30
-sun protection is found in makeup and other products used for the face. Look for products with SPF 30 or higher.
-sunscreen needs to be reapplied every 80 minutes when exposed to the sun. Reapply after swimming or toweling off.
-Physical barrier sunscreens sit on the surface of the skin and can be slightly thicker and chalkier. Physical sunscreens include titanium dioxide and zinc oxide. There are a number of chemical barrier sunscreens each Different UVA/UVB specific coverage. Most products use a combination of physical and chemical barriers to achieve their specific SPF. Fewer people are allergic/sensitive to the physical sunscreens..
-Spray sunscreens can seem convenient but may offer less coverage. When spraying, some of the product may not reach the skin. To prevent missed areas, lotion/cream formulations are preferred.
-several sunscreens available at Cary Dermatology contain antioxidants to help repair sun damage while they are blocking the UV rays. Others are better for sensitive skin.
