Hectic everyday life, harmful environmental influences, and stress: Is your complexion showing the consequences in all shades? Go back to square one and create a new foundation! SOS Primers are tailored solutions for optical correction of the complexion. The "High Lumitech" complex with pearlescent and soft-focus pigments brightens shadows and reflects as well as diffuses incoming light advantageously. The concept of SOS Primers is based on the principle of the color wheel: When two opposite colors – known as complementary colors – are layered on top of each other, they neutralize each other. Choose the primer in the color that is complementary to the imperfection you want to conceal. The result: Color variations are neutralized, and the complexion is balanced and even.
