Phototypes

Every individual has a certain amount of the skin pigment melanin in their skin, which protects the body against UV radiation. Long-term evolution and the need to adapt to natural conditions have resulted in differences in skin pigmentation in different populations, which are now genetically determined.

Expresses the intensity of pigmentation - the natural colour of the skin and is determined by the response of skin to exposure to spring or early summer midday sun. This reaction correlates with skin pigmentation, eye and hair colour. The lighter the skin, hair and eyes, the lower the skin phototype number. As the phototype number increases, the skin's resistance to sunlight increases.
