What it is: A densely pigmented concealer for the under-eye area, and where needed on the face, in a stick form. What it does: Yves Saint Laurent ANTI-CERNES Multi-Action Concealer hides any imperfections so that you can put your most flawless-looking face forward. It eliminates the look of blemishes while reducing puffiness and inflammation. The soft, creamy texture is easily blendable on the delicate skin around the eyes and light-diffusing pigments help to fade the look of even the most offensive looking mark.
