Which layer of the skin is primarily affected by microdermabrasion?

Microdermabrasion is a minimally invasive procedure that focuses primarily on the outermost layer of the skin, known as the stratum corneum. This layer is composed of dead skin cells that provide a protective barrier for the underlying layers of the skin. The goal of microdermabrasion is to exfoliate this surface layer to improve skin texture, reduce the appearance of fine lines, and promote cell turnover.

By mechanically removing the stratum corneum, microdermabrasion helps to reveal the healthier, more youthful skin underneath. This exfoliation can enhance the absorption of topical products and aid in the overall rejuvenation process.

The other layers mentioned, such as the stratum germinativum (which is involved in the regeneration of the skin), the dermis (which contains connective tissue, hair follicles, and glands), and the stratum granulosum (which plays a role in the formation of the skin's barrier), are not directly targeted by microdermabrasion treatments. This procedure is designed to primarily impact the outer layer where the most visible skin imperfections occur, making it effective for superficial skin concerns.
