My son started this, it improved his acne but unfortunately, he was one of the unlucky ones who noticed a sudden change in his mood. He felt depressed and came off it straight away. Luckily he told me. Now he’s at uni and is still struggling with his mental health. The Flag of American and Mexico shirt dermatologists do warn you of the side effects however you don’t think you’ll be one of the minorities who suffer. We wish he’d never tried it. My wife took it many years ago and it was fantastic. No serious side effects except skin peel and dry lips. Her skin was so bad before the treatment but after acne free.
