I tried the beginner version based on reviews, but I didn't feel any pain, just a tingling sensation. I wonder if this is what it feels like to use a lip balm. My lips turn slightly red. It has a transparent gloss finish. I read in reviews that lip balm won't stick, and I need lip balm for my skin, so I hope it's effective. I don't feel any pain, so I think I'll try the expert version next time.
