This stuff DEFINITELY helps clear your skin fast, but if your acne is due to hormonal issues, it will not stop it from occurring. It will, however, heal it faster than anything I have seen on the market (I work in natural skincare so I have tried it ALL)! Effectiveness super easy to apply and does not leave messy or sticky feeling on skin. The cleanser is also easy to use. Just add a little water and thoroughly massage in a circular motion. Ease of Application I just wish they had smaller, travel sizes because I travel often and the cleanser is a pump cleanser without a lid to prevent spillage. Would be cool if the cleanser and serum came in a small pack to-go. Convenience the first couple times you use the serum, it will probably turn your skin bright red for about a half hour after use. otherwise, its great! The redness is due to the fruit acids that work to naturally exfoliate your skin. Side Effects I found this products to clear up large areas of cystic acne in about 3-4 weeks. Also, the serum works great as a spot treatment when you just have a few blemishes to reduce. It definitely takes away redness fast! Immediacy I think anyone with acne should give this product a go...it has helped me so much!
