What is the term used for the cosmetic treatment of the stratum corneum?

The term that specifically refers to the cosmetic treatment of the stratum corneum is "esthetics." This field focuses on skin care and beauty treatments, including the care of the outer layer of the skin, which is the stratum corneum. Estheticians are professionals trained to perform various services such as facials, exfoliation, and other skin treatments, emphasizing improving the appearance and health of the skin.

Dermatology primarily involves medical treatment and diagnosis of skin diseases and conditions, rather than cosmetic applications. Aesthetics, while similar in spelling, is a broader term related to the appreciation and study of beauty and taste, not specifically about skin treatments. Cosmetology encompasses a wide range of beauty services, including hair, nails, and skin; however, it does not focus exclusively on the treatment of the skin’s outermost layer as esthetics does.
