Filtri solari chimici e fisici: facciamo chiarezza

Chemical and physical sunscreens: let's clarify

When the days warm up and summer arrives, the first desire is to undress and let the sun kiss you. Whether it's lying on the beach or taking a bike ride, you can rediscover the pleasure of being in the open air. Unlike the philosophy valid until a decade ago, where you wanted to be black at all costs to the detriment of skin health, in recent years we have finally returned to greater attention to protection, favoring the health and youth of the skin. If it is true that the sun allows the absorption of vitamin D by strengthening the bones, it is also true that the skin must be protected from possible burns which, for the skin, are real traumas. In fact, it should be remembered that the process of melanogenesis (tanning) is nothing but a reaction that the body puts on  in place to protect against sun damage.

Our allies par excellence in the hottest season to enjoy the summer in full respect of the skin are sunscreens, which protect us from UVA and UVB rays. Protection that not only protects the skin from sunburn, but also from premature aging.

What are UVA and UVB rays?

Both are ultraviolet rays from the sun which, crossing the atmosphere, reach us with different wavelengths. UVA rays are able to penetrate to the dermis causing an alteration of the collagen fibers and premature aging of the skin; UVB rays have a lower penetration force but are responsible for burns, rashes and other skin problems.

To enjoy only the beauty of the sun, it is therefore necessary to protect the skin from damage and to do this, sunscreen products are enriched with filters which, depending on their concentration, protect the skin more or less effectively. As we all know, the higher the number with which a sunscreen is identified, the greater its strength. Less known is that there are filters of different types and that give life to different types of products.

Physical and chemical sunscreens: the differences

Let's clarify these filters to use them in the best possible way and with the utmost awareness. There are two types:

Physical sunscreens

Also called inorganic, they tend to be filters of mineral origin such as titanium dioxide for example. They have the task of reflecting the sun's rays exactly like a mirror, not allowing the penetration of ultraviolet rays. These filters create a real external barrier which is dispersed in the water when it comes into contact with it without penetrating the body. They are used in full-bodied and creamy sunscreens.

Chemical sunscreens

Also called organic, they are made up of molecules capable of absorbing part of the UV rays by converting them into another type of energy such as heat and do not work by refraction like physical filters. On the regulation of their use, the law sets very precise rules so that they are not toxic to humans or to the environment. They are an excellent choice for sunscreens with a light and watery texture, guaranteeing maximum skin breathability.

In our brand new sunscreens, we have decided to focus on maximum protection for the skin by choosing the latest generation chemical filters to guarantee an extremely light and comfortable skin film, an impalpable and pleasant texture of the product also suitable for the hottest days when there is less desire to feel the skin covered with product.

Both in Elixir Sun and in Sunlover we find a very light, extremely spreadable and pleasant formulation which, with the addition of selected ingredients such as celligent (in the case of Sunlover) and ectoine and echinacea stem cells (in the case of Elixir Sun) , become a real anti-aging and anti-smog treatment.

We also want to remind you that sunscreens, although excellent in summer or in the sun (even in the mountains in winter), should be abandoned during the rest of the year so as not to overload the skin with molecules that are not needed to replace them with more suitable products to the different season.

Happy summer, happily tanned and protected to all!
