“Now that the summer is over, is it still necessary to wear sunscreen on a daily basis?”
Warm & sunny summer days have given way to cool and rainy “west coast” autumn weather. That is NO REASON to put your sunscreen away. There are different types of light that reach the earth’s surface. “UVB” refers to the sun’s energy most responsible for a sun burn. UVB is strongest on a sunny summer day. “UVA” refers to the sun’s energy that penetrates more deeply into the skin and contributes to the aging effect of the sun. UVA is present in much higher amounts on the earth’s surface and it is fairly consistent ALL YEAR LONG. UVA even reaches the earth’s surface on a cloudy day.
In order to protect your skin from the aging effects of the sun, photo protection should be consideration 365 days a year. Don’t forget that sun avoidance behaviour and protective clothing are your best defense against sunburn, minimizing skin cancer risk and photo aging. Beyond that, a daily skincare regimen can be designed to protect against UVA, UVB, visible light and even infrared.
The two key components of photo protection in a skincare regimen are a daily antioxidant serum and a high SPF and broad spectrum (UVA and UVB) sunscreen. An optimal skincare regimen, including photo protection, can be prescribed in consultation with your cosmetic dermatologist or physician.
