The Function of Skin

Home >

Our face is made up of 3 layers. The epidermis, dermis, and hypodermis. Each layer has its own function and role to play.

The Epidermis

Is comprised of 5 different layers. There are no nerves or blood vessels in this layer. This is the part of the skin that we see as it is the outermost layer.

  • Stratum corneum - contains tightly packed skin cells that are no longer in use. When we are young, our skin sheds these cells with ease. As we get older, we must supplement the natural aging process and manually exfoliate them so that our complexions do not appear dull.
  • Stratum lucidum - translucent cells that light can pass through. Using a sunscreen that reflects light to protect your skin will ward off premature aging.
  • Stratum granulosum - where cells die and are transferred to the outermost layer of skin so that they can be shed.
  • Stratum spinosum - cells with spiny threads that bind together with the basal layer. This is where moisture is held. The higher the moisture level, the more supple a complexion appears.
  • Stratum germinativum (also referred to as stratum basale) - this is where the effect of sun damage can begin to appear. Age and brown spots begin to show in the form of a dark pigment.

The Dermis

This is the inner layer of our skin and is also the most important. It is very delicate as it contains blood vessels, nerves, sweat and oil glands, hair follicles and papillary. It's function is to provide elasticity to the skin through collagen fibers. The papillary that provide nutrients to the epidermis. It does this with "finger-like" extensions are called the papillae.

The Hypo-dermis

The function of the hypo-dermis is to house fat and connective tissue.
