What type of material can microdermabrasion crystals commonly consist of?

Microdermabrasion crystals are typically utilized for their exfoliating properties, and aluminum oxide is one of the most common materials used for this purpose. Aluminum oxide crystals are favored due to their effectiveness in removing dead skin cells from the superficial layer of the skin without causing significant irritation. The size and shape of these crystals make them ideal for creating a gentle yet effective abrasive action, which helps to promote cell turnover and improve skin texture.

While other materials such as silicon dioxide, calcium carbonate, and magnesium sulfate may have uses in various cosmetic applications, they are not standard choices for microdermabrasion. Silicon dioxide is often found in silica gels or as an abrasive agent in different contexts, but it doesn't provide the same level of effectiveness or safety in microdermabrasion treatment as aluminum oxide. Calcium carbonate is more commonly associated with abrasive cleansers and not typically used in professional microdermabrasion devices. Magnesium sulfate, while beneficial in some skin applications, does not serve as a crystal option in the microdermabrasion context. Therefore, aluminum oxide’s properties align perfectly with the objectives of microdermabrasion treatments.
