Titanium dioxide (TiO2) and zinc oxide (ZnO) are natural broad-spectrum physical sunscreens of mineral origin known to be safe and effective by international expert committees. Presented in the form of inert white powders capable of reflecting and scattering ultraviolet radiation, visible radiation and, to a certain extent, infrared radiation.

Ectoin is an amino acid that acts as a moisture shield. Naturally present in the skin, it develops in conditions of extreme temperatures. Its role is to protect the skin barrier against external aggressions such as cold, dry air, pollution and exposure to blue light, UVA and UVB rays. It also contributes to better skin elasticity and reduced water loss. 

The vitamin E moisturizes and helps form a film on the skin, reinforcing the skin's cutaneous barrier. Hydration is maintained and the skin remains protected from drying external aggressions (sun, wind, cold, etc.).
