Protecting Your Skin in the Summer Months


Summer is here, and so is the heat! Before you step outside, remember to apply high-quality sunscreen to protect your youthful-looking glow. But, with TV commercials constantly talking about UVA and UVB rays, SPF numbers, how to apply sunscreen, and when, choosing the right sunscreen for you and your family can be a challenge.

To ensure you’re fully covered, we turned to the Skin Cancer Foundation website to better understand summer’s most buzzed-about words. Let’s begin. 

What are UVA and UVB rays? 

Ultraviolet (UV) radiation from the sun cannot be seen with the naked eye, yet it penetrates the atmosphere and can negatively affect skin health. Classification of UV rays is based on wavelength. UVA rays have a longer wavelength than UVB rays. Most people will be exposed to a large amount of UVA rays during their lifetime. These rays account for about 95 percent of UV radiation that reaches the earth’s surface and are able to penetrate both clouds and glass during daylight hours any time of the year. UVA rays are also the main contributors to giving people a tan; UVA rays penetrate deeper into the skin than UVB rays and play a major part in aging (think A for aging) and wrinkling. UVB rays, then, are the reason why people get red from a sunburn (think B for burn), and in the United States, are mainly present from mid-morning to mid-afternoon from April to October.

What is SPF? 

Sun protection factor, or SPF, is a measure of a sunscreen’s effectiveness and specifies the length of time it will take UVB rays to redden or burn skin. So a sunscreen with an SPF of 30 will take 30 times longer to burn skin compared to using no sunscreen.

How much sunscreen should you apply and when? 

About 1 ounce of sunscreen, or 2 tablespoons, should be applied to the entire body about 30 minutes before heading outside. Sunscreen should be reapplied every two hours or immediately after excessive sweating and/or swimming.
