High pressure and after several phone calls and wheels and deals... I finally gave in for hair removal and skin tightening... Omg, I wished I had never done it. Never have had such high pressure, I feel like they are hounding me every time I go in there and I have not had any reduction and the equipment they use is not safe and it is old. Please do not go to american laser center. They have 2 offices. One in st. Charles and the worst one in chesterfield. Ran by the mafia I do believe in michigan... It is a scam company. I am so sorry I spent over $1500... And am out of all it and no hair reduction and burnt!
