Which crystals are commonly used in particle microdermabrasion?

• A. Aluminum Oxide Crystals
• B. Sodium Chloride Crystals
• C. Cornmeal Crystals
• D. Glass Beads

Answer: (A)

In particle microdermabrasion, the abrasive material must provide controlled, uniform mechanical exfoliation of the outer skin layer. Aluminum oxide crystals fit this need because they are very hard, chemically inert, and come in defined particle sizes, allowing the practitioner to abrade the stratum corneum safely and consistently while suction removes the crystals and skin debris. This combination gives predictable results and minimizes trauma. Sodium chloride crystals, being softer and soluble, don’t offer reliable, uniform abrasion and can irritate or clog the treatment area. Cornmeal crystals are irregular and coarse, leading to uneven exfoliation and potential residue. Glass beads can be less uniform and may present safety concerns with breakage or uneven texture, making the outcome less controlled.
