The effect of UV radiation on the skin and hair

The sun's UV rays age the skin. They damage the fibroblasts, an important cell type of connective tissue, which causes increased collagen degradation. In addition, the skin loses elasticity, takes on a yellowish-pale color and thickening, it form wrinkles and wrinkles. At some point, the skin looks like tanned leather - doctors speak of elastosis. Above all, a long and intense UV radiation can cause skin cancer.

Too much sunlight is harmful to the hair as well: The rays destroy the protein structure of the hair, damage its cuticle and dry it out. The result is brightened, brittle, lackluster and brittle hair that is difficult to comb. The sun damage on dyed and permanently wavy hairs is particularly serious.

UV filter in care products

To protect against the damaging effect of UV radiation, many day creams and hair care products contain UV protectors. There are chemical and physical sunscreen substances. Known examples of chemical UV filters are butyl methoxydibenzoylmethane (UVA filters), zinc esters and PABA derivatives (UVB filters) and benzophenones (broadband filters). The main physical filters are mineral pigments such as titanium dioxide, zinc oxide and silicates.
