I had used similar products and used potentlift as directed. I woke up with my entire forehead horribly wrinkled.I had had only a very few minor wrinkles. Even worse, it caused the skin above my mouth to be horribly horribly wrinkled. I Had had only one line above my mouth. This was 2 years ago and even help from a plastic surgeon couldnt fix it at all. It RUINED my face. I now use Plexiderm which helps My forehead a little. The wrinkles above my mouth are still horrible. This is the worst product Ive ever seen or used. User's recommendation: DO NOT USE THIS!
