What is the acid mantle?

  1. A protective barrier made up of sebum, lipids, sweat, and water

  2. A layer of skin that produces melanin

  3. The outermost layer of the epidermis

  4. A layer of cells that helps absorb nutrients

The correct answer is: A protective barrier made up of sebum, lipids, sweat, and water

The acid mantle is a protective barrier made up of sebum, lipids, sweat, and water. This barrier plays a crucial role in maintaining the skin's pH balance and protecting it from external factors such as bacteria, pollutants, and moisture loss. It ensures that the skin stays hydrated, healthy, and able to defend itself against potential irritants or infections.
