I have thin skin under my eyes and tried so many concealers to hide the veins, I lost track of how many concealers I tried because every day I'd buy a new one. This is the best concealer out there together with the Nars Complete Concealer, however the Nars concealer does not come in my color, it's either too light or dark. The Pur disappearing concealer comes in exactly my shade which is Porcelain. Porcelain is a fair-light shade in a neutral tone.
I usually dont wear foundation and this wears well on it's own, it blends in naturally with the skin, although it goes well with foundation too.
