The biggest reason I have used this product for about 5 years is because it keeps making a noticeably difference. Not only does it keep my skin acne clear, but I love the product because it’s works at controlling and keeps the oil pockets, that I have under neath my eyes banished. Once I stop with the Differin now I have a difference that I can’t stand. It is a very gentle product and I like the glow it gives my skin. The acne gel is a must too! Also recommended by my dermatologist! And she’s never stirred me wrong on products!
