The best aging secret isn’t a miraculous product worth hundreds of dollars. If you spend any time in the sun (yes, that means even 10 minutes), the number-one thing you can do to prevent age spots, wrinkles, and discoloration is to protect your skin with SPF. Here at The Village Spa located in Carmel, we share the most recent advancements in SPF that provide you with ample protection from the sun.
1) UVA vs. UVB Protection
In the late ’80s, almost all of the research concerning sunscreens was devoted to UVB protection. Even though UVB is the primary burning ray, UVA is now recognized as the primary contributor to aging the dermis. Even on the market today, Sun Protection Factor (SPF) only shows the rating for how much UVB is screened, but not UVA. Even if a product claims UVA protection, there is no regulation for actually testing how much UVA is absorbed. We recommend using a higher value SPF in the 30-50 range to screen some of the ultraviolet rays in the lower UVA spectrum.
2) Won’t Help a Visible Burn
You need to reapply sunscreen every two hours in addition to reapplying after swimming or sweating. However, a common misconception is that if the skin shows sign of redness, you need to lather on more SPF to prevent additional burning. With the skin already desensitized to the sun, the small amount of UV protection that the sunscreen can’t stop will continue to burn the skin. If your skin is turning red, get out of direct sunlight immediately.
3) No Such Thing as Sunblock
Previously, the FDA said that products that provided a minimum of SPF 12 could be marketed as sunblocks. In 1999, the term sunblock was ruled as not an honest way to describe SPF. An SPF 15 protects 93% of UV rays, SPF 30 provides 97% protection, and SPF 50 covers 98%. From there, the percent difference between an SPF 50 and higher ratings is so small that full protection is unattainable. You cannot protect your skin from 100% of UV rays, so actual “sunblock” is a false claim.
