I don't understand the bad reviews. Maybe expectations were too high, but I love it! It goes on smoothly, it smells absolutely incredible! It does have a slight sting, but I'm sorry, if you find the sting unbearable or even troublesome, you have an incredibly low pain tolerance or beyond sensitive skin. It stings only for a few minutes, and it's not even that bad. My lips look amazing afterwards! No, it's not going to make your lips crazy big, but there will be a noticeable difference, and I have relatively small lips, so it's perfect for me! The only thing that might deter is the fact that it is sticky, but I don't mind it. It stays on for hours and so does the plump. I love this product, and I think as long as you aren't expecting crazy results, you will love it too.
