Microderm crystals are primarily known to contain aluminum oxide, corundum, and which other ingredient?

Microdermabrasion crystals are primarily known for their effectiveness in exfoliating the skin, and one of the key ingredients that enhances their abrasive properties is silica. Silica is a common mineral that is widely used in various beauty treatments due to its ability to provide smooth and mild exfoliation. In microdermabrasion, it works alongside aluminum oxide (which is also known as corundum) to help remove dead skin cells and promote cell turnover. This combination of ingredients creates a skin-resurfacing treatment that can improve a variety of skin concerns, such as texture, fine lines, and overall appearance.

In contrast, while salt, sugar, and calcium have their own uses in different skincare products, they are not typically components of microdermabrasion crystals. Salt and sugar, for instance, are more commonly found in body scrubs, and calcium does not serve the same exfoliating purpose as silica in this context. Therefore, recognizing that silica is a primary ingredient alongside aluminum oxide is important for understanding the formulation and effectiveness of microdermabrasion treatments.
