Early verdict · Few reviews so far

What the gurus are saying

This mask earns praise as an affordable sulfur option for acne-prone skin. Dermatologists note it can be used flexibly (rinsing immediately for shorter contact time or waiting the full ten minutes for stronger benefit) making it particularly suitable for those on a budget, with sensitive skin, or milder acne. The light blue color change signals when it's ready to rinse.

"This product also by AcneFree is an Acne Clearing Sulfur Mask. This has 3.5% sulfur in it. You can find products with higher percentages, maybe up to around 10% sulfur, but again it can be drying to the skin, so I like to start low at least in the beginning. You can increase as needed, but this is a great product that will help cut down on the amount of oil and sebum on the skin and that will help clear your acne."

"The most affordable option is by Acnefree. It's called the Acne Clearing Sulfur Mask. You massage this onto the skin until it turns light blue, then you let it dry for about ten minutes and then rinse it off. You can also rinse it off immediately if you want less contact time on your skin and you can still get benefit that way. [...] Choose the Acnefree if you are on a budget or have more sensitive skin or less severe acne."

"There's the Acne Free Clearing Sulfur Face Mask on the wishlist."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Vitamin C

Topical vitamin C is an antioxidant with reasonable evidence for dullness and uneven tone. It breaks down in light and air, so how a product is formulated and packaged matters as much as the percentage on the front.

Sunscreen filters

Sun protection is the best evidenced way to slow visible ageing, and the filters are what does the work. Mineral and chemical filters both protect when a product is applied thickly enough and often enough, which is where most people fall short rather than on the choice of filter.
