I used this product on my problem areas. I never had acne growing up but had the occasional spot once a month or when I was a bit stressed or ate too much rubbish foods. Recently I was pigging out so had a few spots on my upper lip and chin. The product was really easy to use. At first I never really liked the fizzyness, my skin felt tingly underneath and was difficult not to itch it off. After a couple more uses I could see my spots reduce drastically. I have used this for over around 2 weeks now and my spots are gone. Usually I would have popped my spots before, picking the scabs and repeating which would cause scarring. I love that this product was so easy to use and I got excited in my evening routine using the mask. I received this product complimentary of Influenster for testing purposes and would definitely recommend others to use for breakouts and blackheads.
