The skin is composed of three main layers: the epidermis, dermis, and the underlying fat layer. The epidermis itself can be further divided into several parts, with the outermost layer being the stratum corneum, which helps retain skin moisture and reduce bacteria. Understanding the accumulation of dead skin cells in the stratum corneum and the appropriate exfoliation methods is crucial for maintaining healthy skin.
Dead Skin Cells Accumulation
During the body’s natural metabolic process, new skin cells are continually produced while dead skin cells are shed. Typically, this process takes about 28 days. However, due to increased air pollution, aging-related metabolic slowdown, or excessive oil production, the stratum corneum may accumulate, causing the skin to appear dull, yellowish, or grayish. A thickened stratum corneum can also increase the risk of clogged pores, leading to issues such as blackheads and acne.
Exfoliation Precautions
Here are some situations in which exfoliation should be avoided:
When the skin is experiencing an allergic reaction or is sensitive to the ingredients in exfoliating products (e.g., the skin becomes red, itchy, or stinging after use), exfoliation should not be performed.
If there are open wounds or ruptured acne on the face, exfoliation should be avoided, as product ingredients may penetrate the deeper layers of the skin and cause further damage.
In cases of eczema, the skin’s oil content is insufficient, and careless exfoliation may irritate and harm the skin. Exfoliation should be avoided during eczema flare-ups.
Understanding the causes of dead skin cell accumulation and appropriate exfoliation methods is vital for maintaining healthy skin. It is essential to pay special attention to your skin’s condition when exfoliating and avoid the process in unsuitable situations to protect your skin’s health.
