Question

A)7 days
B)28 days
C)2 weeks
D)21-24 days

Answer 1

Skin cells have an average lifespan of 28 days before they are shed, and this process is part of the natural cell turnover that maintains skin health.

Step-by-step explanation:

The average lifespan of skin cells before being shed or sloughed off is approximately 28 days. This process is part of the cell turnover where cells from the lower layers, such as the stratum basale, move up to replace the shed cells in the stratum corneum. This cycle is essential for maintaining the health and protective function of your skin. Factors like psoriasis can disrupt this process, leading to a much quicker turnover and the development of characteristic skin patches.
