Understand the causes of skin disease

The skin is a moving part of the body and failure in any of its functions can lead to serious consequences. The skin's ability to act as a barrier is especially important for health.

One way to understand the functional impact of the stratum  is to think of it as a brick wall. Keratinocytes (made of hard tissue) form bricks, and inside the bricks there are two layers of lipids (oily substances) and water that form the mortar. Some lipids have a hard, crystal-like structure and are waterproof. Other lipids do not have this structure and allow water to enter. Therefore, the barrier is semi-permeable.

The elasticity, stiffness and normal function of the stratum  depend on its moisture content. Chemicals in the skin called natural moisturizing factors (NMF) help retain moisture. Too much or too little moisture will affect the barrier properties of the skin.

Excess moisture on the skin, for example from prolonged contact with water or from wearing gloves that prevent sweat from evaporating, can increase NMF production.

If the skin is dehydrated in a cold environment without moisture, keratinocytes cannot be produced normally and the skin becomes rough, thick and flaky, thus causing cracking due to loss of elasticity.

"Wood film" of the epidermis also acts as a barrier, preventing bacteria and other pathogens from entering the skin. The film is slightly acidic and helps neutralize normally alkaline bacteria. Excessive use of strong alkaline solutions can acidify the film, thus destroying the protection it provides.

Problems occur when the skin is affected. This will happen in the following cases:

Ingredients/agents enter sweat ducts or hair follicles and cross the barrier layer.

The protective response of the skin is inherently limited. The most common is inflammation. This is called dermatitis or eczema. It is characterized by heat generated due to dilation of local blood vessels, swelling and blisters due to plasma leakage from blood vessels into tissues, and stimulation of nerve fibers causing irritation. Secondary changes from infection and scratching include rashes, sores, and blisters.

Dermatitis caused by dysfunction or imbalance in the body is called endogenous or bacterial dermatitis. Active dermatitis is caused by exposure to certain external factors. This is called exogenous dermatitis or commonly known as dermatitis.

External factors often come into contact with the hands and forehead, so approximately 95% of active skin diseases occur in this area. Most of the rest is on the face. Most active diseases of the skin are called dermatitis. A small number of other skin functions are related to other factors. These include urticaria, acne, cancer, vitiligo (white spots) and skin diseases.
