The skin is a complex active organ, if any of its functions fail there can be serious consequences. The skin’s ability to act as a barrier is particularly important for occupational health.
One way to understand the barrier function of the stratum corneum is to consider it as a brick wall. The corneocytes (made of tough protein) form the bricks and between these a double layer of lipids (fatty materials) and water make up the mortar. Some lipids have a hard crystal-like structure and are impermeable to water. Others lipids do not have this structure and they allow water to percolate through. So, the barrier is semi-permeable.
Anything that irritates or clogs the skin can cause symptoms such as redness, swelling and itchy skin. Rashes and hives are other signs of skin conditions. Some are quick and easy to treat, while others are chronic or more difficult to get rid of. Find out about conditions like acne, cold sores, scabies, shingles, tinea, warts and more in this section. You can also use the healthdirect Symptom Checker to check your symptoms.
