My toes were bleeding by the end, I had small cuts on 4 toes. That was only getting previous shellac off. I said at the time, “you keep nipping my skin”. She said sorry but kept doing it. I came home and took my shoes off and my white socks had red blotches. She seems like a nice person but 100% do not recommend. I have no idea why or how they managed to get ratings so high.
