UV Filter

UV filters are essential ingredients in sunscreens, designed to protect the skin from the harmful effects of the sun's ultraviolet rays. They are divided into two main categories: chemical filters, made up of chemically modified carbon compounds, and physical filters, composed of an assembly of mineral microparticles. Discover how to choose the UV filters that suit you, for optimal protection.

FAQ about uv filter

What is the difference between a chemical filter and a mineral filter?

A chemical filter creates a thin filtering film that absorbs UV rays and dissipates the energy in the form of heat. A mineral filter, on the other hand, diffracts and reflects UV rays by creating an opaque barrier.

Do UV filters prevent tanning?

The UV filters do not completely filter out UV rays. A small proportion reaches the epidermis and triggers the synthesis of melanin, which is responsible for tanning.

Are UV filters effective against both types of UV rays?

This depends on each UV filter: some filter UVA rays, some filter UVB rays, and others filter both. That's why it's important to prioritize cosmetics that combine multiple filters.

Are UV filters safe for children?

Yes, UV filters are safe for children. However, it is recommended to avoid chemical filters and only use mineral filters on the delicate skin of children under 2 years old.

Can UV filters interact with other cosmetic ingredients?

Yes, certain UV filters can interact with other ingredients. That's why it's recommended not to mix sun care products with other cosmetics, but to apply them separately.
