What type of crystals are used in microdermabrasion?

Microdermabrasion typically utilizes aluminum oxide crystals, often referred to as corundum. These crystals are favored for several reasons in the microdermabrasion process, primarily due to their fine, abrasive quality that effectively exfoliates the outer layer of dead skin cells. Aluminum oxide is also biologically inert, making it safe for use on various skin types without causing adverse reactions. Furthermore, the crystals' durability and effectiveness ensure both consistent results and minimal discomfort during the treatment, contributing to the procedure's popularity in skincare. Other options may be used in different contexts or products but do not offer the same level of efficacy and safety for microdermabrasion specifically.
