Facts About Harmful UV Rays
- There are two types of sun rays which are harmful to the skin, UVB and UVA, corresponding to different wavelengths of the solar spectrum. K2 Endurance Sunblock provides protection against both.
- UVB rays penetrate only the first layer of the skin (epidermis) and are primarily linked to short-term skin damage including sun burns.
- UVA rays penetrate into the deeper layers of the skin (dermis) and are primarily associated with long-term skin damage like skin cancer and premature aging.

K2 Endurance Sunblock Advanced Sunscreen System
Our unique formulas contain 4 prescription-grade FDA-approved sunscreens, Avobenzone, Homosalate, Octocrylene and Oxybenzone, to help cover the complete UVA and UVB spectrum. Complementing each other, this combination screens out UVB burning rays and helps stop UVA rays from penetrating your skin's surface layers for exceptional, deep cellular protection.
Better UV Protection
The SPF value of sunscreen describes how long this product protects against sunburn caused mainly by UVB rays. However, the SPF value doesn't show how well you are protected against UVA rays. These rays don't burn your skin, but rather cause long-term skin damage potentially leading to skin cancer.
K2 Endurance Sunblock has been formulated and tested to deliver superior protection well beyond the FDA requirements for both UVA and UVB rays.
