I was absolutely fascinated by this product when I discovered it. It is definitely not your typical lipstick. Even though it is green in colour it reacts to the alkali levels in your lips to match create a tone that perfectly matches your skin colour
I am a big Barry M fan and love the bright colours and tones they produce and this lived up to my expectations of quality. I tried this on 4 other people and every time it had an obvious change in colour (from light pink right through to red) and each colour matched the person perfectly.
It has aloe vera added in so it goes smoothly onto your lips, softens them making the lipstick look silky smooth.
The lipstick its self never gets tinted with the colour it appears on your lips and remains its green colour.
Overall it is very good at matching the right shade of lipstick to your skin colour and to be honest is worth buy for how interesting and unique it is.
