desquamation

Full Definition

The natural shedding or peeling of the outermost layer of skin (stratum corneum) that occurs in newborns, especially those born post-term. This process is normal and typically begins within the first few days of life, often starting on the hands and feet before progressing to other body areas. Post-term infants show more pronounced desquamation due to decreased vernix caseosa protection and longer exposure to amniotic fluid. The process usually resolves within 1-2 weeks without intervention.

Usage

Usage note: Often misspelled; note the 'qu' combination. Distinguish from pathological skin conditions.
