-Force protection, type of skin, duration of sunshine, these factors rely heavily in choosing a sunscreen. Dr. Michel Jeanmougin, dermatologist at the Saint-Louis hospital, expert Afssaps and co-author of “the skin and the Sun”, explains in detail how to choose the product that corresponds to the skin of each.
“Three criteria are to be taken into account in choosing a sunscreen: the type of skin, exposure, and the category of protection.” “On class usually skin according to four types: the skin extremely sensitive, very white, found in the red, clear, blond for example skins, intermediate skins, and finally the resistant hides, as flat skins”, explains Michel Jeanmougin.

Second choice, the power of exposure, which can be extreme, important, moderate, or current. If expose two hours under the Sun of a tropical place is obviously not the same dangerousness for the skin to expose a few minutes in a place where the rays of the Sun are less powerful.

Finally, the exposure time influence the dangerousness of the rays of the Sun. In any event, experts recommend not to expose between noon and 4 p.m.. Clothing, and the category of solar products also influence this type of protection.

Protection of sun creams indices vary between above 50, and the lowest rates from 6. The French Agency of sanitary safety of health products (Afssaps) class these protections in four categories, very high protection, greater than 50, high protections, 30 to 50, medium protection 15 to 29, and the weak, of 6 to 14.

“People with sensitive skin should in all cases use higher indices of protection creams”, says Michel Jeanmougin. People with the most resistant skins can afford to use less strong protective creams.

Of course, more time spent in the Sun is long, more the rays of the Sun are strong, and more protection cream must be high, depending also on the skin of each type.

“Ideally, we must apply the cream in the morning, arriving at the beach for example, then many respect a break between noon and sixteen hours.” “Then, must be apply once again of the cream by returning to the place of exhibition, to 16 h 30-17 h”, describes the doctor Michel Jeanmougin. “By and large, must be applied the cream every two hours”.

Creams and sprays on the market sufficiently moisturize skin, according to the dermatologist. But the latter recommends to apply a care in the evening, after a day of sun exposure. “Next”.
