Microdermabrasion Crystals are a skin refining technique used in the finest spas and dermatological offices in the world. They work by using specially treated Aluminum Oxide crystals to "sand" away the top layers of the epidermis and by stripping away the dead and dull layers of your skin, smoother, more even toned skin is revealed. Using these crystals also enhances the ability of the skin to absorb other skin care products fully and efficiently. Perfect for home use, these crystals are sold loose and there is a very important reason for this. Many of the at home dermabrasion kits use heavy, lipid rich creams as the suspension base for the crystals. While this may be fine for someone with very dry tough skin, it can wreak havoc on sensitive, oily or acne prone skin! By shipping the crystals loose, each client can safely and easily add them to their favorite cleanser or cream, one for their specific skin type and one that they know works with their skin. The crystals can also be used with just water, to keep the system as simple and pure as possible! And as an added bonus, the crystals are not just for use on your face! They can be used on any part of the body (Keep out of your eyes) where you want smoother, more even toned skin. These Microdermabrasion Crystals come in a 2.5 oz Bottle. An 8 oz bottle is also available for your convenience:)
