I went a long time without using under eye concealer, but needed to start using it. I purchased this Jean-Michelle Satine Concealer about 3 weeks ago, and have used it everyday since. I use a powder type base, and was afraid that this might be too obvious, but is not. This concealer goes on very smooth and blends right in with my skin tone, there are no noticable lines under my powder. I have light dark spots and fine lines under my eyes, but this really hides the inconsistance in my skin tone. My eyes look much more youthful, and adds a nice, natural glow to my face. It is not very thick, and is easy to "blotch" on under my eye. I just pat a few small dots under my eye area, and gradually blend this in. I can not believe I skipped so many years without using a concealer. This is my new "must have"
