How The Skin Works

Can you imagine how we would look if we did not have skin covering us up? That may be too gross for your imagination.

The skin is the largest vital organ of the human body. It covers you up, keeps you warm and keeps you cool. It also decides what can be absorbed and what should be rejected.

Skin that is clogged and unhealthy is not just a beauty problem. It can become a hindrance to your sense of vitality and wellness. Proper care of your skin is important not only to your personal sense of beauty but also to proper elimination, more graceful aging and overall health.

The skin has five main functions:


It acts as a mechanical barrier to infections. It ultimately prevents micro-organisms and other substances from entering the body.

Langerhans cells (a type of macrophage) which are found within the dermis, engulf invaders and debris foreign to the body.

Keratin layers in the epidermis together with sebum produced by sebaceous glands act as a waterproof barrier.

Melanocytes protect the body from ultraviolet light.

Fingernails and toenails protect the extremities of fingers and toes from damage. Fingertips are important for dexterity and the sense of touch; they have ridged areas to assist in picking things up.

Hair follicles offer some extra protection to certain parts of the body such as the eyes and head.


Your skin regulates body temperature. Considerable heat is lost through the skin. Even under extreme conditions of high temperature and exercise, our skin tends to make body temperature normal. The production (evaporation) of sweat in the skin cools us down when exposed to too much heat.

The core body temperature needs to be kept constant for normal physiological activity to take place (37c). It needs to maintain a core temperature for homeostasis.


Skin excretes waste product and excess salt from the body. Sweat includes waste products in solution. Water is lost continuously through the skin as insensible sweating. More pronounced water loss through sweating occurs as part of temperature regulation.


Skin provides the sense of touch or sensation we need to know more about our outside environment through recognizing heat, cold, pain and other sensations. Nerve endings of the skin provide the body with a great deal of information about the outside environment.


Skin synthesizes the use of Vitamin D in the presence of sunlight and ultra violet radiation needed for the absorption of calcium and phosphate.

So take care of your skin. No other organ in our body will perform these functions for you.
