Which machine is specifically designed to remove a portion of the epidermis?

1. Laser machine

2. Microdermabrasion machine

3. Chemical peeler

The procedure promotes new cell growth and can improve skin texture, tone, and overall appearance. Microdermabrasion is particularly effective for addressing superficial skin concerns such as dullness, fine lines, and minor scars. The targeted approach of this machine allows for controlled exfoliation, making it a popular choice in esthetic treatments for clients seeking to rejuvenate their skin with minimal downtime. In contrast, while laser machines, chemical peels, and dermaplaning tools also contribute to skin resurfacing and exfoliation, they operate differently. Laser machines typically work by targeting deeper layers of skin and can vary in their intensity and results. Chemical peels involve applying a chemical solution to the skin, which may penetrate beyond the epidermis depending on the strength of the peel. Dermaplaning tools are used to physically exfoliate the skin by removing dead skin cells and vellus hair but do not specifically categorize as a machine designed for epidermal removal, as they rely on manual
