Most volcanic clay masks work in about 10 minutes, and leaving one on much longer can dry out your skin. For Volcano Mask, apply a medium layer to a clean face, focusing on problem areas and avoiding the eyes. Leave it on for up to 10 minutes, then rinse with lukewarm water or towel it off.
The directions allow use 2 to 5 times a week. If clay masks are new to you, start with one or two sessions a week and build up as your skin adjusts. If your cheeks run dry, apply it only to your T-zone, chin and breakout areas. Follow with an oil-free moisturizer such as Nano Clarifying Hydrator.
