This 1 Smelly Product Just Might Be the Key to Curing Your Acne

With a 10 percent concentration of sulfur, Peter Thomas Roth's Therapeutic Sulfur Masque ($47) is a force to be reckoned with. Because of its potency, this mask is meant be used only once or twice a week, and it effectively reduces breakouts and minimizes oil production. Reviewers especially herald the mask for its ability to melt away blackheads and treat deep, cystic acne.

It has a soothing, cooling effect on the skin, is ultracreamy, and smells very pleasant despite its high concentration of sulfur. It also contains aloe vera to help soothe inflamed or irritated skin and kaolin and bentonite clay to further mattify.
