Inert minerals designed for microdermabrasion use are known as:

• A. Aluminum Oxide Crystals
• B. Silica Beads
• C. Magnesium Flakes
• D. Calcium Carbonate

Answer: (A)

In crystal microdermabrasion, the abrasive material must be hard, chemically inert, and biocompatible so it can exfoliate safely and predictably without reacting with skin or topical products. Aluminum oxide crystals meet these needs because they are a stable, non-reactive mineral that provides strong mechanical exfoliation. Their high hardness allows efficient removal of the outer dead skin layer, while their inert nature minimizes irritation and chemical interactions, making the treatment safer to perform. That combination is why aluminum oxide crystals are the standard choice for crystal microdermabrasion. The other minerals listed are not used as the primary abrasive in this context because they don’t offer the same reliable combination of hardness, safety, and inertness.
