On June 16th we reposted our opinion on Sunscreens and SPF ratings: "Consumers were misled into believing that the higher the SPF (Sun Protection Factor) the greater the protection, and of course, prolonged exposure. The truth? The higher the SPF does not necessarily mean improved, prolonged protection. In fact, there is not much difference in the protection of a SPF of 15 which blocks 93.33%, a SPF of 25 that blocks 95 %, or a SPF 30 at 98.6%. And, while it is important to ensure adequate UVA and UVB protection, there is no point to a SPF higher than 30." Then, we read an article showcasing new sunscreen products lining the shelves boasting SPF ratings all the way up to 110. Oh my! Dermatologists and other skin care professionals, including the Editors at Beauty Editor Post, agree that SPF ratings this high are completely unnecessary. The American Academy of Dermatology recommends an SPF of 30 and reminds sunbathers that sunscreen needs to be reapplied every few hours. Remember, SPF ratings only protect your skin from 95% of UVA rays (the ultraviolet light responsible for skin cancer and the formation of wrinkles) and only 5% of UVB rays, which causes a sunburn. The SPF rating is only indicative of the UVB, not the UVA protection. Confused? Let's make this easy. Invest in a good sunscreen with a SPF rating of 30, apply lots of it every few hours, and be sensible about sun exposure. Moderation is the key. Sense and sensitivity prevail.
