First off, this is such a fun ,concept! The product itself is sheer, so it’s kind of a surprise as far as what it’ll look like once applied. I can’t lie I was a bit skeptical about the ph effect, but I tested it on my self and then my husband and the colors were COMPLETELY different! I was very pleasantly surprised by the color and how beautiful and Dewey it is! It’s just as beautiful as a blush as it is a shimmery lip tint! I’ll definitely be buying the product again and again!
