How to Maintain a Skin Barrier
Advertisements for skin care products can be overwhelming. Turn on your television or open a magazine, and the odds are there will be a multitude of advertisements for creams and lotions. Every brand seems to be touted as the next best thing to help your skin look young and fresh. But is all this fussing really necessary?
While skin may seem uncomplicated compared to other parts of the human body, it is actually a sophisticated and complex human organ. Understanding and appreciating this organ means more than just tending to it after a sunburn, acne breakout, cut or scrape. To help keep your skin at its best, you need to understand a crucial function of this vital organ -- the skin barrier.
To understand the skin barrier, start by taking a closer look at the structure of the skin itself. The skin consists of three main layers, each with own unique function and purpose. The subcutaneous layer is the innermost layer. It is made up of fat, which is used as a fuel reserve and for insulating the body. Next, the dermis contains tiny blood vessels, hair follicles and nerve endings that detect pain and pressure. The dermis is very flexible and can detect changes in temperature.
The outermost layer, the epidermis, is the key to the skin barrier. Made up of overlapping layers of dry cells, the epidermis keeps vital nutrients in and damaging substances and elements out. It also helps keep moisture in the body [source: National Geographic].
