Sun tanning cosmetics are a prerequisite for relaxing on the beach. These cosmetic products contain ingredients that block the negative effects of UV radiation. They act as a kind of chemical filters that penetrate the skin and reflect the sun's rays. Due to this, ultraviolet light cannot adversely affect it and thus does not lead to photoaging in the future. At the same time, the use of such products does not prevent the gradual appearance of a healthy tan, without the unpleasant result in the form of burnt skin.
