This is a mud-based, strong cleansing mask intended for oily skin. The main ingredient bentonite is a type of clay that is used as an oil-controlling absorbent in cosmetics, especially for oily skin. It also acts an active thickening substance that keeps the homogenous form and maintains the moisture levels. But it could be overdrying. So do not use this mask more than twice a week.
However there are two ingredients that could cause serious concerns. The third abundant ingredient propylene glycol at low concentration is used as a humectant or humidifying and delivery ingredient to keep from drying. It is easily absorbed through skin. At higher concentraion it could a potent skin irritant. PG could provoke skin irritation and sensitization at concentration as low as 2%. In fact U.S. Environmental Protection Agency (EPA) has issued a warning to avoid skin contact to prevent brain, liver, and kidney abnormalities. What's the exact concentration of PG in this product is not clear.
The other troublesome ingredient is talc. Talc is naturally occurring silicate mineral of magnesium. It gives skin a slippery sensation and water resistance. However, talc is very similar in structure and properties to the potent carcinogen asbestos. Talc have been shown to cause tumors in the ovaries and lungs. In 1973 FDA warned about limiting the amount of asbestos-like talc in cosmetics but no ruling was made. As a result cosmetic grade talc remains non-regulated by the federal government. Even without any asbestos-resemblance cosmetic grade talc has been reported to cause tumors in animal subjects in 1993 National Toxicology Program studies.
Consider this is a mask product that only comes in contact with skin once or twice a week, these may not be that big a concern. Use caution when use this product. Stop using if there is any sign of irritation.
There are moisturizing ingredients to offset the drying effect, such as sweet almond oil, avocado oil and hyaluronic acid.
