Sunscreen: everything you always wanted to know

There sunscreen it is the most important gesture of the baby care routineepidermisgiven that it not only prevents blemishes caused by UV rays but, above all, it protects from the risk of developing malignant pathologies of the skin.

How long does sunscreen last once opened?

«From protocol for any dermocosmetic, including photoprotectorsyou must stick to the Paowhich stands for period after opening (symbolized by an open jar with a number inside, it is found on the bottle and indicates how many months the integrity of the formula is guaranteed for, ed.). In general we can say that from one summer to the next it is necessary to change the product otherwise you risk no longer being protected as the active ingredients alter, losing effectiveness” explains Dr. Menicanti.

When to put sunscreen?

«The photoprotector should always be worn, even in the city, on photo-exposed areas such as face, neck, décolleté and back of your hands every time you expose yourself to UV rays, therefore every morning before leaving the house, especially if you live in sunny areas and in hot seasons.”

How long in advance should I apply sunscreen?

There are those who don’t like using theSpf complaining of a greasy feeling on the skin, or simply only remembering it when they are already at the beach or pool. By applying the product on sweaty or sand-stained skin, however, you risk compromising the homogeneity of the application, which is why, explains Menicanti, it is necessary to apply the lotion “about half an hour before exposing yourself”. Much better to apply it at home, away from wind and light, where we can also check that we have placed it well everywhere.

Should I use a filter even if I have dark skin?

«Certainly yes, dark skin types are less at risk with regards to epidermal damage caused by UVB rays, such as the development of actinic keratoses and non-melanoma skin cancer, but they are not free from dermal damage, such as wrinkles and loss of elasticity, generated by UVA rays.”

If I wear 100 protection, does that mean I can stay in the sun all day without getting burned?

“Not at all. Because the SPF does not indicate the exposure time I have available but the degree of filteringor the sun’s rays of a certain product. Every sunscreen, regardless of the number indicated on the label (i.e. from 30 upwards, given that below this threshold it is not considered valid for protecting the skin from the rays) must always be rigorously reapplied every 2 hours».

Is it a good idea to use specific formulas and protection factors for children?

«During the first year of life, the formation of the skin, therefore of the epidermis and dermis, is still ongoing in progress, which is why it is better not to expose them to direct sun, always keeping them in the shade. The filters most suitable for children are those physicists of mineral origin because they guarantee maximum protection but the minimal absorption of chemical substances, also considering that, in the early stages of life, the skin is very thin. After the year they can expose themselves to the sun, but only if well protected.”

Does mixing sunscreen with foundation guarantee or compromise the effectiveness of the filter?

«Mix themoisturizing or the colored base to sun protection it is a mistake to avoid because it inevitably means diluting the protection factor. When applying the sunscreenIn fact, the quantity is important: when in doubt, just keep in mind a practical rule. The lotion we apply on two fingers of the hand it is the perfect quantity, the one that guarantees optimal protection for the skin of the entire face. If you need coveragegiven that there are now cutting-edge formulas with a very pleasant texture, you can rather use the colored photoprotectors».
