The ph lipstick that changes shades according to your ph is awesome. It starts out clear and then changes. The first time I put it on it turned hot pink within 60 seconds, then the following day I wore it and it turns a toned down pink tone. It is really neat how it changes colors and I looks at my soda can after drinking and no shade was on the rim. I was amazed! It also did not dry out my lips like many other products that I have tried. I would recommend this lipstick to others for sure.
