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

This Colloidal Sulfur Mask by Dr. Dennis Gross ($42) works best on skin that is sensitive, irritated, and acne-prone. Its creamy and thick consistency spreads well over your face, chest, and back, and it gently cools the skin while it works its magic.

In addition to the five percent colloidal sulfur, which targets and blasts oil and acne, it contains kaolin and bentonite clays to further clarify. It's also formulated with licorice root extract, an anti-inflammatory ingredient that reduces hyperpigmentation caused by acne, and prickly pear to further reduce redness and irritation. Because it also contains retinol, which nixes wrinkles and fine lines, it's great for aging and dry skin.
