What are the three layers of the skin?

The three layers of the skin are indeed the epidermis, dermis, and subcutaneous layer. The epidermis is the outermost layer, primarily responsible for providing a barrier to infection and regulating water loss. Beneath the epidermis is the dermis, which contains connective tissue, hair follicles, and sweat glands, playing a crucial role in skin strength and elasticity. The subcutaneous layer, also known as the hypodermis, lies beneath the dermis and consists of fat and connective tissues, providing insulation and cushioning for the body.

This combination of layers allows the skin to function effectively in protection, sensation, and thermoregulation. Understanding these layers is essential for studying skin functions and health, as well as their relevance in early childhood development where skin protection from environmental factors is crucial.
