Doesn't do magic but definitely works well if you have some smaller pimples or you're dealing with some marks

I had a really really bad hormonal acne breakout last year bc I had to stop taking birth control pills and absolutely nothing worked. I'm to blame tho because I was trying way too many things all at once (I had never dealt with acne before and was desperate lol) and had a damaged skin barrier.
