- Producing melanin
- Cell division and renewal
- Providing a protective barrier against moisture loss (Correct answer)
- Housing nerve endings
Correct answer: Providing a protective barrier against moisture loss
The stratum corneum is the outermost layer of the epidermis and acts as the skin's barrier, preventing transepidermal water loss.
