Microdermabrasion primarily affects the stratum corneum, which is the outermost layer of the epidermis. This layer consists of dead skin cells that continuously shed and are replaced by newer cells. The process of microdermabrasion involves the use of fine crystals or a diamond tip to exfoliate the skin, removing the dead skin cells and revealing fresher, healthier skin underneath.

The treatment is designed to improve skin texture, reduce the appearance of fine lines, and promote a more radiant complexion. By targeting the stratum corneum directly, microdermabrasion enhances cell turnover and can stimulate the production of new skin cells, making it a popular choice for superficial skin concerns.

The other layers listed, such as the dermis, stratum lucidum, and stratum granulosum, play different roles in skin structure and function. The dermis is beneath the epidermis and contains blood vessels and connective tissue, whereas the stratum lucidum is a thin layer found in thick skin areas, and the stratum granulosum is where cells start to keratinize. These layers are not the primary focus of microdermabrasion, as the treatment is aimed specifically at exfoliating the uppermost layer.
