Physical filters and chemical filters, what are your differences?

There is growing concern about the composition of cosmetic products, and solar protection was not going to fall behind. But speaking of photoprotection, there is another booming debate: physical filters or chemical filters?

Physical filters act as a screen reflecting light and diverting ultraviolet rays to prevent sunburns, and their composition is of mineral origin.

Zinc oxide and titanium dioxide are the most common ingredients used in natural protectors and have a great advantage, especially for smaller ones, which is that they cannot be absorbed by skin.

"until recently, there was a false belief that physically protected solar protectors were dense, oily or off-white... but not all are so if you know how to choose a natural option with a proper formulation," says Rocío L. Cuesta, Dr. 'cum laude' in pharmacology and CEO of Alma secret.

Today, physical filters are added biological filters and organic ingredients that also add to solar protection, to make their texture and protection perfect.

The Alma secret photoprotectors are formulated naturally and are ideal for all kinds of skins even for the most sensitive and reactive, and also for the little ones in the house. Its star ingredient is Arabian Cotton, a natural and innovative biotech active extracted from stem cells from Arabic cotton. This incredible plant lives in extreme sun conditions and acts by strengthening the skin cells' own defense mechanism to combat photoaging, sunburn and the appearance of pigmentation spots.

It is very important to wear a sunscreen for the face and another for the body as the skin is different and needs different properties.

Chemical filters have always been used in solar protection, there are all the textures imaginable: more fluid or denser, in spray, oily... They capture solar energy and transform it by protecting the skin from the sun.

Its main drawback is that, although all those used in cosmetics should be safe, when absorbed through the skin they can cause certain allergies. In addition, they should be applied about 30 minutes before solar exposure.

Physical filters do not need to be applied 30 minutes before exposure to the sun as, from the moment they are applied, they are already protecting the skin.
