How Sunscreen Protects Your Skin

The active ingredient in sunscreen is one of two chemicals: a UV absorber or a UV reflector. You may have seen “chemical sunscreen” or “physical sunscreen” on bottles of sunscreen and wondered what those words mean. If you choose to wear a chemical sunscreen, then the active ingredient will absorb the UV rays so they don’t penetrate your skin. A physical sunscreen creates a barrier between your skin and the sun, thus reflecting the rays off of your body. 

What Does SPF Mean?

SPF is short for “sun protection factor”. This rating denotes just how much sunlight is allowed to penetrate your skin. Remember, no sunscreen can completely block 100 percent of the sun’s rays. Sunscreen only acts as a screen, which means that some UV rays will and do penetrate your skin. An SPF 30 sunscreen means that 3.3 percent of the sun’s rays do come into contact with your skin. This is why most dermatologists recommend that the absolute lowest SPF that you use on a daily basis is 30.

When Should I Apply Sunscreen?

While you may think that your skin is completely smooth, it actually is made up of ridges and valleys. Applying sunscreen at least 20 minutes before you go outside will allow the sunscreen to settle into your skin and bind to your skin. Better yet, if you’re planning to spend several hours outdoors or you’re going outside at peak UV radiation times, apply one coat of sunscreen and then follow up with a second coat for an added layer of protection. If you’re unsure of the peak UV radiation times for your area, a good rule of thumb is to avoid the sun for two hours leading up to the solar noon and then for two hours after. Noon is the time when the sun is the most intense and thus has the most radiation.

Protecting your skin from UV radiation is essential to reducing your chances of skin cancer and signs of premature and early aging.
