I love this product. I was surprised at how well it really works to fight acne blemishes. I carry this with me in my purse and if I feel acne coming on, I use it right away. It really helps to dry out acne, even the toughest cystic acne. I would get acne spots that would literally hurt under the skin. This product quickly helps dry out the acne and help with healing. I could not say more about this product, it is fantastic. I have tried the very expensive products, to the cheapest of products and this has been my favorite by far. Effectiveness Works very well to control new acne blemishes from coming, and also to heal very quickly. Ease of Application This product is very easy to use, simply put a dot of this gel on the affected area for fast relief. Convenience I carry this product in my purse, and do not leave home without it! Side Effects I have never had any side effects from this product. It does not cause any redness or irritation and I have very sensitive skin. Immediacy This product works very fast and I quickly see results!
