I have been using the product for some time and I've nearly finished the bottle.
I do think that it works well to prevent further breakouts, but in terms of moisturizing the skin I think it has little effect and wears off before long, making my skin dry again. So, I would suggest opting for a better brand.
By the way, I couldn't give my review a lousy one star because it didn't exacerbate my acne.
Hope this helps.
