Introduction The flexible, waterproof, tough protective covering known as the skin is the largest organ in the body both by weight and surface area. Skin accounts for approximately 16% of the body’s weight. Healthy skin has a fine texture that is slightly moist, soft, and flexible. Varying in thickness, the skin is thinnest on the eyelids and thickest on the palms and soles. A callous can be caused by continuous friction on any part of the skin.
The skin has appendages that include the hair, sweat and oil glands, and the nails. Composed of the substance known as keratin , this protein gives the skin its protective ability. The skin is slightly acidic in pH, which enables good immunity responses to intruding organisms. Normally the skin separates the internal environment from the external. However skin diseases and infections can invade that barrier. For this reason, a thorough understanding of the histology of the skin and its diseases and disorders is needed for a better position to give clients professional advice.
Learning objectives Upon completion of this course, trainees will be able to: Explain the structure and the composition of the skin. Identify the functions of the skin. Describe terms relating to skin disorders.
Recognize which skin diseases/disorders may be dealt with in the salon and which should be referred to a physician. Identify online dermatology resources.
ANATOMY AND HISTOLOGY OF THE SKIN
The epidermis consists of many layers. The stratum corneum is the outer layer that is often called the horny layer . Cells are continually being shed and replaced. This layer of skin for the most part is dead – it is composed of cells that are almost pure protein. The stratum lucidum consists of translucent cells through which light can penetrate.
The two major divisions of the skin are the dermis and the epidermis. The outermost layer of the skin is the epidermis that is composed of sheets of dead cells that serve as the major waterproof barrier to the environment. The epidermis is the visible layer of skin. This layer contains numerous nerve endings, but no blood vessels. The human epidermis is renewed every 15-30 days.
