Very effective in clearing and preventing acne.
However, its effect of removing oil is so great that it really dries the skin.
For me, it actually dried up so much that it peeled off my skin.
For people with severe acne or really oily skin, this product might be it.

I love this product! I like that the first product is water! I've tried different exfoliating gels and what makes this one different from the others is that I can actually feel and see it working. You can really feel the crystals, and your face just feels so much cleaner and fresher afterward.
I've only ever used it at night as it says in the package; although not daily. I think if used daily, your skin will get very dry and then go into overtime creating more oil which causes unwanted pimple visitors. I suggest avoiding using any other acne product in conjunction with this product. Exfoliating gels are quite strong products and using other acne products at the same time would definitely over dry your skin. I've seen only good results and I'm happy with this product.
