Did you know how your skin protects you from UV radiation?

Our skin is more than just a surface; it is a true protective organ. Every day it is exposed to sunlight and UV radiation, and yet it has its own fascinating ways of keeping us safe. 

In the deeper layers of the skin are melanocytes, small cells that produce melanin, our natural sun protection. When sunlight touches the skin, it triggers the production of more melanin. This pigment forms a fine protective layer over the cell nuclei and helps shield the sensitive DNA from damage. This process shows itself as a natural tan, the visible response of your skin to sunlight. 

Over time, the upper layer of the skin, the stratum corneum, also thickens. It acts as an additional filter, blocking some of the UV rays before they can penetrate deeper. At the same time, the skin uses its own antioxidants, such as vitamin E and vitamin C, to neutralize free radicals, small molecules that are formed by UV rays and can damage cells. 

But as strong as these mechanisms are, they have their limits. Too much sun can overwhelm the skin and, in the long term, lead to premature aging, pigmentation spots or even skin cancer. That’s why daily sun protection with SPF is so important. It supports the skin in what it already does for us every single day: protecting us and keeping us healthy.
