Silhouet-Tone brand Corundum Crystals are created for use with our crystal microdermabrasion units. Corundum crystals (aluminum oxide) are one of the hardest natural minerals in the world, second only to the diamond in hardness. Our crystals are medical grade and have been thoroughly tested by an independent laboratory for safety and sterility. They have been processed under extremely sanitary conditions and purified with special acids. Crystal microdermabrasion is a useful technique for many skin concerns such as aging, sun damage, acne scarring, and blocked pores.
