I love this handy little tool. It makes my skin feel so clean and firm. The first time I used it, I didn’t feel anything so I thought it maybe wasn’t working. But for the next few hours after using it, my skin sorta tingled. I have combination skin and I live in a dry climate. I also had adult acne in my twenties. Now I want to heal those old acne scars and prevent wrinkles. I feel like this is definitely helping.
