I've been using this concealer for a little while now and i absolutely love it! With my undertone being yellow this goes great with fair to medium skin only if you have a yellow undertone. The formula is light and you can also build each layer you put on. Blending with this concealer is also made easy because of the non-heavy formula. When blending out i do suggest using a blending sponge but a brush will do as well. I've tried other concealers that were drugstore as well but this one just can't be beat!
