Our SPF 30 blocks 96.6% of the sun’s UV rays, satisfying the ADD recommendation for broad-spectrum protection (UVA/UVB) with a minimum of SPF 30. UVA rays cause photodamage, leading to accelerated skin aging – brown spots/discoloration, fine lines, wrinkles, and skin laxity. UVB exposure can cause precancerous cells and skin cancers. Our sunscreen protects against both. Our SPF 30 sunblock is also chemical and irritant free, containing a natural, physical sunblock that’s good for skin – Zinc Oxide. We use no chemical sunscreens, such as oxybenzone/octinoxate, so it is a safer alternative with no skin irritation or potential for allergy. And, as an added benefit, our sunscreen is antioxidant rich. It is abundant in Vitamin E and ferulic acid antioxidants which increase the photoprotective benefits of the sunscreen and contribute to moisturized, glowing skin.
