With more than 40 minerals, micronutrients and trace minerals this glacial clay is composed of particles as fine as mist. The particle size of the clay is less than 0.15 of a micron, meaning that it is absorbed into the skin to deliver its nutrients directly into the dermis. Glacial marine clay has a pH factor of 6.5 to 7.3, close to neutral, which is desirable for skin and hair applications. With the addition of moisture and other ingredients such as glycerin or floral hydrosols it can be used to exfoliate skin cells, stimulate blood circulation, rejuvenate tired complexion and renew skin elasticity; leaving your skin refreshed, alive and glowing. Glacial Marine Clay is an excellent therapeutic and cosmetic clay and is frequently used in facial and body masks, poultices and salves. A silky warm gray color when wet, it dries in fifteen to twenty minutes (depending on the thickness of application) to a light aqua-marine hue.
