I've struggled with acne my whole life and I have tried EVERY product out there. I finally realized that sulfur is the most effective ingredient on my particular skin. This product not only contains sulfur but it also includes ALL NATURAL versions of salicylic acid and benzoyl peroxide. It's a trifecta of goodness! This product is so light, it absorbs immediately so you can apply your moisturizer right on top of it. I am one picky customer and I am honestly impressed with this stuff! My skin is much improved!
