Which layers of skin are affected by microdermabrasion?

Microdermabrasion primarily affects the outermost layers of the skin, specifically the stratum corneum and stratum granulosum. The stratum corneum is the top layer of the epidermis, consisting of dead skin cells that act as a barrier to protect underlying tissues. Microdermabrasion works by exfoliating this layer, effectively removing the dead skin cells to promote a smoother, more even skin texture.

The stratum granulosum is located just beneath the stratum corneum, and it plays a crucial role in the process of keratinization, where skin cells begin to die and form the protective barrier. By targeting these two layers, microdermabrasion can help in improving overall skin appearance, reducing fine lines, and addressing issues such as uneven pigmentation and texture.

Other layers of the skin, like the stratum basale and stratum spinosum, are part of the lower epidermis and are not directly impacted by microdermabrasion. Similarly, while the dermis contains important structures such as blood vessels and connective tissue, it is not reached during a microdermabrasion treatment, which is focused on the superficial layers of the epidermis. Thus, understanding the specific layers that
