With the Solaire Lacté spray, Biotherm presents an ultra-light sunscreen spray that provides intense hydration in the lightest form of all milk textures. The Biotherm star ingredient Life Plankton regenerates, protects, and strengthens the skin in a unique way, building up the natural skin barrier. This makes the skin more resilient against external influences such as sun, wind, and water. A photostable broad-spectrum filter system protects against UV-A and UV-B rays, ensuring maximum protection against sunburn and skin aging. Glycerin prevents skin dryness and replenishes the skin's moisture reserves.
