PROTEXTREM

It is a brand of Ferrer laboratories and is developed on the basis of rigorous clinical studies and backed by strict dermatological controls. Ferrer has more than twenty-five years of experience creating and manufacturing dermocosmetics and is present in more than ninety countries all over the world, because its aim is to ensure the care of people and improve their quality of life.

They are the main element of sunscreen and their mission is to reflect, scatter or absorb the sun's rays, thus protecting the skin from the harmful effects of the sun. Depending on how they act, they can be broadly classified into two main groups: The most common are physical filters (they reflect radiation, scattering it) and chemical filters (they absorb the energy of UV radiation).

As a whole, sunscreens are considered to be safe molecules. However, the use of some chemical filters such as oxybenzone or octocrylene is controversial, especially in young children and sensitive or reactive skin, due to a higher probability of skin absorption and allergic reactions, and also in those with stratum corneum integrity problems.

Physical filters: these are mineral particles that act as a broad-spectrum "screen", reflecting solar radiation. This type of filter attenuates ultraviolet (UV), visible and infrared (IR) rays.

Chemical filters: they convert ultraviolet solar radiation and transform it into another type of energy that is harmless to the skin. ?

To minimise all these risks, it is recommended that sunscreens with physical filters be used preferably on sensitive skin. Inorganic filters, such as zinc oxide and titanium dioxide, have the advantage of being very photostable and do not cause allergic reactions. Emulsions incorporating inorganic filters would be the most suitable to avoid sensitisation, irritation and photoallergy.
