In skincare terminology, what does "desquamation" refer to?

Desquamation refers specifically to the process by which dead skin cells are shed from the surface of the skin. This is a natural part of the skin's renewal cycle, contributing to maintaining healthy skin. The outermost layer of the skin, known as the stratum corneum, is continuously undergoing a shedding process. As old cells die off, they are replaced by newer cells emerging from the deeper layers of the skin.

Understanding desquamation is important in esthetics because it directly affects skin texture, clarity, and overall appearance. Proper exfoliation techniques can aid in facilitating this process, helping to remove the dead cells more efficiently and revealing the fresher, more radiant skin beneath. This process is essential for maintaining healthy skin and can influence other factors such as product absorption and the effectiveness of skincare routines.

The other options, while related to skin health, do not define desquamation. For example, absorption of nutrients pertains to how the skin utilizes products, production of skin oils relates to the skin's barrier function, and inflammation involves the skin's response to irritation or infection. Understanding each of these functions is important in skincare, but they do not align with the specific definition of desquamation.
