Human skin has three layers - the epidermis, dermis, and subcutaneous tissue. As the outermost organ, skin protects the body from pathogens, regulates temperature, and prevents water loss. Skin can be damaged through severe injury, resulting in scar tissue formation. Skin type and pigmentation varies between populations and provides a habitat for bacteria.

environment, skin plays an important
immunity role in protecting the body

synthesis of vitamin D, and the
protection of vitamin B folates.

by melanin) varies among populations,
and skin type can range from dry to non-
dry and from oily to non-oily. Such skin

The epidermis is the upper layer of skin.

constantly flake off and are renewed. In
these layers are three special types of
