How many layers of skin are there?

The skin is structured into three primary layers, each with distinct roles and characteristics. These layers are the epidermis, dermis, and hypodermis (also referred to as subcutaneous tissue).

The epidermis is the outermost layer, providing a barrier to environmental factors and containing cells responsible for the production of skin pigment. Beneath the epidermis lies the dermis, which houses connective tissue, hair follicles, and various glands, contributing to the skin's strength and elasticity. Lastly, the hypodermis acts as an insulating layer that helps to regulate body temperature and provides cushioning.

Understanding the three-layer structure of the skin is essential for comprehending various aspects of skin health, protection, and the way these layers interact with factors such as hydration, UV exposure, and products applied to the skin.
