What Does SPF 50 Mean?

The SPF (sun protection factor) on your protector solar tells you how well the product protects your skin from ultraviolet radiation. The higher the SPF number, the more UVB-blocking protection the product provides. When you apply an SPF 50 sunscreen, your skin can be exposed to 50 times more UVB radiation without burning, but there's a catch. All sun protection products require frequent application.

How Long Does SPF 50 Last?

SPF 50 sunscreens give you more UV protection than products with a lower SPF. However, that number has little to do with how long your protection lasts. Instead, it tells you the amount of solar energy your skin can tolerate safely. Once the active ingredients in your sunscreen interact with the sun's UV rays, they're depleted, used up. That's why it's important to reapply your SPF 50 sunscreen every 2 hours or as directed on the product label.

What Is The Best Sunscreen For Face SPF 50?

The skin on your face is much thinner than the skin on the rest of your body. That makes your face far more susceptible to UV damage. Delicate facial skin is also more likely to react to pore-clogging oils, artificial fragrances and other ingredients that can cause irritation. That's why so many people protect their complexions with sun protection formulated specifically for facial skin. As you browse the SPF 50 sunscreen options at CVS Pharmacy consider how your face might benefit from the following product types:

SPF 50 vs 30

SPF 30 and SPF 50 sunscreens offer significant protection from the damaging effects of ultraviolet radiation. SPF 30 sunscreen can block 97% of the sun's UVB rays. SPF 50 sunscreens block 98%. Although that 1% difference may not seem important, it is. The effects of sun damage are cumulative. Even a slight increase in sun protection today can help make a huge difference in your skin's health and appearance years from now. An SPF 50 sunscreens allows 2% of the sun's UVB rays to reach your skin. A product with SPF 30 allows 3% to pass through. The 1% difference between SPF 30 and SPF 50 represents a 50% increase in UV protection.
