The Science Behind SPF: What Every Sun Lover Should Know

Sun protection has never been more crucial. As the ozone layer depletes and our outdoor activities increase, shielding our skin from harmful UV rays becomes paramount. SPF, or Sun Protection Factor, indicates how effectively a sunscreen can protect the skin. But what's the real science behind it? Let's dive in with XJ BEAUTY.

UV rays can be divided into UVA and UVB. While UVA rays age the skin, UVB rays burn it. A higher SPF rating primarily indicates protection from UVB rays. For example, if your skin normally burns after 10 minutes, SPF 30 sunscreen would theoretically allow you to stay in the sun 30 times longer without burning.

However, no sunscreen can block all UV rays. SPF 30 blocks about 97% of UVB rays, and SPF 50 blocks 98%. The key is regular application and reapplication, especially after swimming or sweating.

With XJ BEAUTY's advanced formulations, we ensure broad spectrum protection, defending against both UVA and UVB rays. Sun safety isn't just about the number on the bottle; it's about using the product correctly and choosing trusted brands like XJ BEAUTY that prioritize both skin health and environmental responsibility.

So, next time you're headed out, arm yourself with knowledge and XJ BEAUTY's reliable sun protection!
