How is the Problem Skin Mask applied and how long should it be left on?

The directions call for applying a thin coat to clean skin and leaving it on for five to ten minutes before rinsing off with lukewarm water. The shorter contact time compared to some other clay masks is intentional, as the active ingredients, particularly the sulfur and camphor, are potent enough to do their work within that window without requiring an extended drying phase. A thin, even application is more effective than a thick one because the active ingredients need to be in contact with the skin rather than simply building up layers. Lukewarm water is specified for removal rather than hot water, which can aggravate already-sensitized skin and strip more moisture than necessary after treatment. Consistent weekly or twice-weekly use within a regular routine produces the most noticeable cumulative benefits for oily and blemish-prone skin over time.
