Fototipi e sole
According to the classification drawn up by dermatologists based on the amount of melanin in the skin and reaction to sun exposure, there are four main skin types. Phototypes 1 and 2 are those with fair, sensitive skin, light-coloured eyes, freckles and blond or red hair. They must be very careful in the sun because they burn very easily and treatment should be started at least two months before exposure. Phototypes 3 (darker skin and brown hair) and 4 resist better but can still burn if they sunbathe without taking precautions.
