In summer it is essential that we use sunscreens. I indicate in this article some guidelines that we must have clear about it. There they go
IDEAS ON THE APPLICATION OF SUNSCREEN
1.Apply sufficient amount
The recommendations of the European Commission indicate that in order to obtain the photoprotector protection rates that we are using, 2mg of cream should be applied for each cm2 of the skin surface. In an adult of the medium constitution. This would be equivalent to 6 tablespoons of dessert or a glass of shot.
We must apply enough every 2-3 hours and always after a bath. It is considered that the water-resistant photoresists lose their effectiveness after approximately 40 minutes of being in the water.
2.Sunscreen is not everything
You will agree with me, after reading the previous section, that very few people apply the correct amount. In that sense, I find this video from the American Academy of Dermatology very illustrative that I recommend you see. It is unlikely that, although a 50+ photoprotector (the highest FPS available on the market) theoretically protects us from 98% of UVB rays. In practice, this is the case.
That’s why we should not forget that sunscreen is just a compliment and that we should not forget to wear glasses, hats, umbrellas or even clothing to adequately protect us from the sun. Continue reading- New treatments for skin diseases
3.Sun protection factor: the higher the better
The concept of “healthy tanning” that is used so much does not exist. Any degree of sun exposure increases the risk of skin cancer to a greater or lesser extent. Like tobacco, any amount is bad: obviously, they will have more ballots to suffer lung cancer that person who smokes 40 cigarettes a day who smokes 4, but nobody can say that smoking 4 cigarettes are “good”. With the sun the same thing happens, although it is aesthetically desirable to have some color, it is important to remember that the skin has memory and that the sun that we accumulate throughout life can take its toll over the years. A melanoma is not a joke, and therefore, it is best to prevent when we are still on time.
Therefore, having creams with SPF 50+, why would we use an FPS10 or FPS30?
I share this video that, in a very illustrative and simple, explains why we should opt for the filters of greater protection.
4.If you have had any allergies, use physical photoresist
In another article, I discussed the differences between chemical (organic) and physical (inorganic) sunscreens. There we said that physical filters have less risk of causing skin allergies (what we technically call “sensitization”). Therefore, if a protector has caused some type of rash before or you have atopic dermatitis, it is more advisable that you opt for a physical sunscreen (inorganic). Traditionally they were considered more unsightly but today there are very cosmetically acceptable products.
5.Do not apply photoresist to babies under 6 months
Before 6 months the babies still have an immature skin. Sunscreen creams contain chemicals (the sunscreens themselves are) that could penetrate it and reach the babies’ blood. Because of this, its use is discouraged before this age.
It is important not to expose babies directly to sunlight and to protect them with umbrellas or clothes. In specific cases where the baby has a small area exposed to the sun a small amount of physical photoprotector could be used.
