As the body’s largest organ, the skin is so important that we often forget that it’s there until we have a problem with it. But when you think about this magnificent suit we’ve given to, it’s no wonder that we get ignore it—it renews itself and heals itself so well that it needs no more care than minimal cleanliness and repair.

The skin is our interface with the outside world. It is present on the body to prevent the tissue fluid and blood from evaporating. In short, the skin supports life in many unperceived ways. Did you know that the skin is the most efficient air-conditioning system ever known? Blood flow through the skin is extremely effective in heat transfer to the outside environment from the internal one.

The skin has developed evaporative and convective cooling so that the slightest change in our emotional state or ambient temperature causes subtle, nearly undetectable changes to control the temperature of our insides within an extremely narrow band.

Our eccrine, watery sweat glands secrete several liters of liquid daily that evaporates insensibly from our skins, taking the caloric heat of food and muscle metabolism with it into the air surrounding us. The skin’s blood vessels widen immediately upon these stresses so that convection currents also expend heat into the environment.

If we didn’t have many of the components of skin, we would die of cold exposure at the slightest insult. The skin’s blood vessels clamp shut to preserve our core heat vital anytime we are exposed to cold. The skin’s fat layer acts like a thick layer of insulation for the vital structures below. Without it we could simply preserve our body heat. It’s as simple as that.

Now think of the way the skin renews itself. It is a perfect covering for the body, fitting every crevice, and as it ages it only sags little

Every twenty-eight days we get an entirely new epidermis, from top to bottom! And a pool of non dividing cells is always at rest in the basement layers of the epidermis ready to take over the function of covering the body should they be needed. Even in old age there is a population of resting young cells waiting to be released into the growth and proliferation phase.

This website is to give you an understanding on how the skin works and what you could do for your skin problems.
