On which skin layer does microdermabrasion primarily work?

1. Dermis

2. Stratum Corneum

3. Basal layer

4. epidermal layer

The correct answer is: Stratum Corneum

Microdermabrasion primarily works on the stratum corneum, which is the outermost layer of the epidermis. This layer consists of dead skin cells that are continuously shed and replaced. The microdermabrasion process uses abrasive particles or a diamond-tipped wand to physically exfoliate this top layer of skin, promoting cell turnover and revealing fresher, healthier skin beneath. By targeting the stratum corneum, microdermabrasion helps to improve skin texture, reduce the appearance of fine lines and superficial scars, and enhance overall skin tone. This treatment is non-invasive and can be performed in a series to achieve optimal results. Understanding this aspect of skin anatomy is crucial for estheticians to ensure they provide effective treatments while maintaining the health and integrity of the underlying layers of skin.
