Many of us have already had the opportunity to escape for a few days to the beach or nature to relax on vacation. And in these escapades, of course, avoiding solar radiation It was almost impossible. Although there is a growing awareness of the importance of protection from the damage that the sun does to our skinThere are also those who hide behind the fact that UVB rays are beneficial for the body (since thanks to them we can synthesize Vitamin D) and don’t take the issue of photoprotection so seriously.
These people are right, but there are many considerations to take into account. To clear up any doubts about this, we at Estetic contacted Dr. Maria Luisa Martos Cabrera, dermatologistDermatology Service of the University Hospital La Princesa (Madrid) An expert confirms that the sun is indeed the main source of vitamin D, but for adequate synthesis it is necessary to take into account amount of time spent in the sun.

Therefore, the indications vary. from 10 to 30 minutes sun per day. Below are general recommendations depending on skin type and season:

On the other hand, for the skin of the entire body, a larger amount is needed, equivalent to two large tablespoons or a shot glass (30 ml), as directed by a doctor.
