HOW DO THE SUN'S RAYS MANIFEST THEIR DAMAGING EFFECT ON THE SKIN?

It is precisely the smallest part of the solar spectrum (UV spectrum) that is the most biologically active and most responsible for acute and chronic skin damage.

UVA rays penetrate deeper into the skin and damage its middle part (dermis). They are responsible for pigmentation and premature skin ageing.

UVB rays are absorbed into the top layer of the skin (epidermis) and are responsible for the acute skin reaction in the form of redness and sunburn caused by excessive sun exposure, leading to skin degeneration and ageing.

UVA and UVB rays are one of the reasons for the increased risk of skin cancer.
