What type of crystals are typically utilized in microdermabrasion procedures?

1. Silica

2. Diamond

3. Aluminum oxide (corundum)

4. Calcium carbonate

The correct answer is: Aluminum oxide (corundum)

In microdermabrasion procedures, aluminum oxide, also known as corundum, is the most commonly used type of crystal due to its unique properties that make it effective for skin exfoliation. These crystals are finely grained and sharp-edged, allowing them to efficiently remove the outermost layer of dead skin cells without significantly damaging the underlying layers of skin. Aluminum oxide is also non-toxic and has a low risk of causing allergic reactions, making it a safe choice for various skin types. Additionally, aluminum oxide crystals can be easily controlled in terms of particle size and pressure during the procedure, which enhances the esthetician's ability to customize treatments for individual clients. The controlled microdermabrasion technique allows for precise exfoliation, leading to improved skin texture, reduced fine lines, and enhanced overall skin appearance. While silica, diamond, and calcium carbonate can also be used in other forms of exfoliation or microdermabrasion devices, they do not have the same level of widespread application as aluminum oxide in this specific procedure. Silica may be less effective for deeper exfoliation, diamonds, though luxurious, can be more costly and less efficient for bulk exfoliation, and calcium carbonate is generally softer, making it less suitable for the precision
