When the sun shines, we receive 2 types of UV rays at the surface of our skin:
UVB:
- represents 5% of the UV spectrum
- are responsible of visible effects such as tanning or sunburns.
UVA:
- represent 95% of the UV spectrum
- penetrate deeply on the skin layers
- are responsible of invisible effects such as oxidative stress and the decrease of skin immune defenses which lead to visible effects such as skin aging and skin cancers.
To avoid these effects and rather than overloading the skin with filters, BIODERMA has created SUN ACTIVE DEFENSE PATENT, the high-technology sun protection, reinforced against UVA rays. It combines 4 – and only 4 – uncontroversial UV filters and a biological protection that improves the capacity of the skin to defend itself to help maintain long-lasting care of its health in the sun and allow:
+24% protection of skin immune defenses*
+26% antioxidant protection*
Our formulation science is crafted with the Dermshield art of formulation, inspired by the natural protective mechanisms of the skin under the sun.
This lipidic complex of vegetal origin, silicon-free, displays a high affinity with the superficial layers of the skin, it creates a protective film acting as a physical shield that optimizes solar protection while increasing the skin barrier impermeability.
1. PHYSICAL SHIELD EFFECT
Our Dermshield art of formulation creates an imperceptible protective film at the surface of the skin, protecting it from external aggressions and irritations.
2. SKIN BARRIER IMPERMEABILITY
It retains skin physiological water, thus maintaining the natural skin hydration.
3. OPTIMISED PROTECTION
This extremely even and stable film maintains sun filters at the surface of the skin and optimizes their distribution. They maintain their protective efficacy despite sweating or bathing, while limiting the spreading of our products in aquatic ecosystems.
