I don’t know if this stuff works or not, I just know that my teenage son was roped into a subscription without his knowledge. I contacted them to let them know they had duped a minor into their subscription scam and they basically said too bad. He thought he was getting a free sample so apparently their ad was set up in a way that he did not know he was going to be charged for a subscription. He only wanted face wash and he was charged over $100. Scam alert.
