Sadly, no sunscreen is able to block 100% of UV rays from reaching the skin. Even a perfectly-applied SPF 50+ sunscreen only protects against ~98.3% of UVB rays.* This leaves ~1.7% of UVB rays with the potential to reach the skin and impact skin health.
One of the most concerning effects being direct DNA damage. Although our skin naturally contains proteins called DNA repair enzymes (which work to limit the damage), these proteins deplete as we age.**
Medik8's solution is to replenish the skin’s natural levels of DNA repair enzymes by applying them topically with Advanced Day Ultimate Protect, diminishing visible signs of DNA damage such as fine lines, wrinkles and discolouration.
