Skin allergies are one of the most typical causes of illnesses on the skin. They are generally caused by a problematic immune system that becomes hypersensitive after being revealed to a certain substance that it views as “harmful” even though it isn’t. As a consequence, the next time these substances enter the body, the immune system discharges vast amounts of antibodies, apparently to fight these “harmful” substances, but in the process cause adverse reactions in other cells of the body.
The substances are called allergens and they can be anything from pollen breathed through the air, to dust mites that thrive in carpets and furniture exteriors. They are also discovered in pets, particularly dogs and cats. Respect skin allergies, they usually appear when the skin comes into contact with skincare products including allergens, cosmetics, perfumes, etc.
How do skin allergies work?
When the immune system overlooks a significance that can potentially cause disease, it creates antibodies called IgG or immunoglobulin G and IgM or immunoglobulin M. With the production of these antibodies, the immune system now evolves sensitized and capable to balance the substance, helping you to recover from the disease after a few days.
As time goes by, your now sensitized immune system is prepared to produce large amounts of antibodies rapidly the next moment it encounters the same substance. This immediate production of antibodies makes you able to heal from the disease quickly so that it’s possible you won’t actually suffer any symptoms.
With skin allergies, on the other hand, the circumstance is a little different. When an allergen – for instance, a cosmetic component– arrives in contact with your skin for the first time, your immune system will also create antibodies, only this time, instead of IgG and IgM, it creates IgE or immunoglobulin E.
The IgE will also attach itself to the cosmetic allergen and does the same thing it did with any generally harmful substance, prompting the sensitization procedure. Without this sensitization, no skin allergies appear.
Because the immune system has already been sensitized to the decorative allergen, the next time you get revealed to it, your body mass produces IgE, which then attaches itself to the allergens, and ultimately the mast cells. The mast cells are a type of cell comprising many chemicals that can cause inflammation, superior among them is histamine. The IgE causes the mast cells to terminate these chemicals to enclose tissue, causing inflammation, redness (erythema), and itching (pruritis) on the exterior of the skin. The response that is seen on the skin surface is called a wheel or a hive and is considered one of the typical symptoms of skin allergies.
Types of Skin Allergy
There are three main kinds of skin allergies: food allergy, contact dermatitis, and atopy or allergic inhaled dermatitis. Skin allergies can be caused by an allergic response to components or preservatives in food, such as horse meat, beef, pork, eggs, fish, chicken, corn, soy, preservatives and pigments, dairy products, and poultry products, etc.
Communication dermatitis is the type of skin allergies caused by allergens coming into direct connection with the skin. Typical among these allergen kinds are poison ivy and ragweed. Ragweed can also be a cause of inhaled skin allergies, as well as, pollen, house dust, dust mites, mould, animal dander, feathers, fodders, trees, and shrubs.
