Desquamation
Desquamation — the natural shedding of dead cells from the outermost layer of the skin, known as the stratum corneum. It is the final visible step of cell turnover, and when it happens evenly it helps keep the surface looking smooth and clear rather than flaky or rough.
Key points
- Desquamation involves the breakdown of protein bonds called corneodesmosomes that hold surface cells together.
- Enzymes and adequate hydration are needed for cells to detach smoothly and invisibly.
- When the process is disrupted, dead cells can accumulate and appear as flaking, roughness, or dullness.
- Gentle exfoliation is sometimes used to support even shedding when surface cells build up.
- Low humidity and a compromised barrier can slow or unbalance normal desquamation.
Frequently asked
Is desquamation the same as exfoliation?
Desquamation is the skin's own natural shedding process, while exfoliation refers to manual or chemical methods that assist or accelerate that shedding.
Why does my skin flake instead of shedding invisibly?
Visible flaking often reflects uneven or incomplete desquamation, which can be linked to dryness, a disrupted barrier, or environmental factors.
