Skin

Structure of the Skin

The skin has three main layers:
Epidermis: The outermost layer of the skin that provides a waterproof barrier and contains pigment-producing cells.
Dermis: The middle layer of the skin that contains connective tissue, hair follicles, sweat glands, and nerve endings.
Subcutaneous tissue: The innermost layer of the skin that contains fat and connective tissue.
The skin also contains blood vessels, lymphatic vessels, and immune cells that help to protect the body from infection.

Human skin structure

There are many skin conditions that can affect the health and appearance of the skin, including:
Acne: A common skin condition that is caused by overactive oil glands, leading to clogged pores and inflammation.
Eczema: A chronic skin condition that causes dry, itchy, and inflamed skin.
Psoriasis: A chronic autoimmune condition that causes patches of thick, red skin covered with silvery scales.
Rosacea: A chronic skin condition that causes facial redness, pimples, and visible blood vessels.
Skin cancer: A type of cancer that develops in the skin cells.
