Sun and your child's skin - what the experts say

Filters and screens

Sun protection products are made up of filters and/or screens:
 

  • Chemical filters are synthetic substances that work by absorbing the energy transmitted by light rays. Depending on how they are made, they absorb only certain wavelengths of sunlight. To ensure effective protection with a wide spectrum, several filters therefore need to be combined. Furthermore, they are not always photostable and – as they can penetrate the skin – there is a risk of phototoxicity and allergy.
  • Mineral sunscreens reflect and diffuse UV rays, irrespective of their wavelength. Mineral sunscreens used in creams are inert and photostable. They form a film on the skin's surface that reduces the risk of penetration – hence the protection they provide.
  • Organic-chemical filters or screens are mixtures of both. They absorb and reflect UV rays, but unlike chemical filters, their very wide spectrum provides greater protection against UV rays. Their photostability and their ability to remain on the skin's surface for long periods of time also make them better suited to the protection of children’s skin.


If possible, you should choose a sunscreen made of mineral screens and/or organic-chemical filters or screens for your child.
