Human skin is not completely waterproof. While it has a protective barrier that prevents excessive water loss and keeps out most external fluids, it can still absorb water.
- The outermost layer of skin, the epidermis, contains a protein called keratin that makes it tough and somewhat resistant to water.
- However, the skin also has pores for sweat glands and hair follicles, which can allow water to penetrate.
- This is why prolonged exposure to water, such as swimming or showering for extended periods, can lead to skin becoming wrinkled and soft.
The ability of skin to absorb water is essential for hydration and can be beneficial for applying lotions and creams. However, it also makes us susceptible to infections if exposed to contaminated water.
