Which material is commonly used in microdermabrasion treatment?

Corundum powder is commonly used in microdermabrasion treatment because it is a highly effective exfoliating agent due to its hardness and fine granule size. As a form of aluminum oxide, corundum provides a strong abrasive action that helps to remove the outer layer of dead skin cells, promoting a smoother and more youthful appearance of the skin.

This effectiveness makes it preferable in professional settings where deeper exfoliation is required for optimal results. Other materials, while they may be used in some contexts, do not offer the same level of efficacy in exfoliation that corundum powder does. In addition, the safety profile of corundum powder in a clinical setting supports its longstanding use in microdermabrasion.
