What is it? Hectic everyday life, harmful environmental influences, stress: your complexion shows you the receipt in all shades? Get back on track and create new foundations. SOS Primer is a customised solution for visually correcting the complexion. The "High Lumitech" complex with mother-of-pearl and soft-focus pigments brightens shadows, reflects and diffuses incident light favourably. The SOS Primer concept is based on the principle of the colour wheel: When two opposite colours - known as complementary colours - are placed on top of each other, they neutralise each other. Select the primer in the colour that is complementary to the blemish you want to conceal. The result: colour changes are neutralised, the complexion is even and smooth.
