I purchased these drops a few months ago as, as a darker skinned woman I quite often find that my the perfect match for my skin tone is 'in between' shade ranges available. However, when I got home, the sight of the twink like formula was enough for me to store this away in my drawer and promptly forget about it. However, a few days ago, whilst having a foundation color crisis I remembered about this little bottle and decided to put all preconceived judgments aside. I'm so glad i did!!! This stuff is awesome! I was able to get my 'perfect' color match by just adding one tiny drop to my foundation. It did not effect the texture of my foundation, in fact I am convinced it makes it feel more silky on my skin while also providing a little extra coverage without that heavy feeling. I am so excited about this product, I have a feeling it is going to become one of my holy grail's and I will definitely be recommending it to people.
