Causes, Symptoms, Treatment and Home Remedies For Skin Allergy.


overview for skin allergy

Skin allergy is an inflammatory reaction that manifests itself in different parts of the body such as feet, hands, mouth, armpits, arms, neck, back, legs, belly, among other areas.

These irritations are caused, mainly by excessive sweat, insect bites, some synthetic clothing, dust mites or dust, contact with metal, exposure to the sun…

Other causes of this annoying pathology are: an allergic reaction to medications, food poisoning, rubbing with plants and animal hairs, as well as contact with cosmetics, creams, detergents, soaps, different cleaning products, deodorant, shampoo, and bath gel.

Currently, 264 million women worldwide suffer from sensitive and allergic skin.

According to the researchers, in 2050, one in two people will develop an allergy, and in 75% of cases, the symptoms will be visible on the skin. Good skincare can reduce skin problems.

This allergy causes specific lesions in the skin, which creates dermatological reactions: eczema, hives, itching or even red patches.

As far as we know, allergies are not inherited, but the propensity to develop allergies seems to be able to be transmitted from one generation to another.

Diseases like eczema can, however, be hereditary. Young children often develop them, such as infant eczema.

This article will give you information about the causes and symptoms, treatment and home remedies for skin allergy.

Causes For Skin Allergy

We know that skin constitutes a barrier that separates us from our environment.

Sometimes the organism becomes intolerant to a substance and reacts at this level with more or less visible dermatological reactions.

It can be eczema, itching, hives, or itchy patches.

These reactions can be caused by so-called contact allergies.

They are so-called because they appear a few hours or even a few minutes after direct contact of the allergenic substance with the skin.

They can be triggered by clothing, cosmetics, household products or even topical drugs.

There are also plants and animals. Besides skin contact, skin manifestations can also be caused by food, drug or respiratory allergy.

Food allergy, for example, is an abnormal defense reaction of the body following indigestion.

Whatever the cause, your doctor will need to be consulted, as the allergy can be serious and even fatal if neglected.

The most common allergies that affect the skin:

1. Perfumes and fragrances

Perfumes and fragrances are one of the most common causes of allergies in adults.

These products cover a large number of options: soaps, body lotions, shampoos, household cleaning products, wet wipes, among others.

It may be the case that even those products labeled ‘without perfume’ can cause contact dermatitis. If you realize that a fragrant product causes allergic reactions, switch to products with natural or other fragrance-free oils.

2. Nickel

Another one of the allergies that dermatologists attend the most is nickel.

This metal is used to create fancy jewelry, some pieces with gold and piercings.

The most common reactions occur in the ears, due to nickel earrings, and can occur at first contact or after much use. Other products that use nickel are watches, lens frames, closures, buttons, belts, cufflinks, etc.

3. Latex

It is increasingly common to find allergies caused by latex.

This is because the amount of products that have it as a base has grown considerably in recent times.

This material is used to make gloves, balls, clothing, hair bands, condoms, and many other products.

The symptoms of latex allergy range from small hives or redness of the skin to difficulty breathing and vomiting.

4. Hair dye

Allergies by contact with hair dye originate from the sensitivity to paraphenylenediamine (PPD), a common chemical in dyes that must be mixed with other substances before being applied.

To avoid the discomfort of this allergy, the sensitivity test should be performed as indicated on the package.

PPD can also be found in other dyes, such as temporary black henna. The most frequent symptoms include itching, pain, and swelling.

5. Poison ivy

Poison ivy is a very common herb that contains urushiol, an oil that causes allergies in much of the population.

This allergy occurs in the form of rashes, blisters, redness, hives and itchy skin.

Urushiol is a sticky substance, characteristic that facilitates its spreading.

The discomfort can be treated at home, washing the affected area with plenty of cold water and using antihistamines prescribed by the specialist.

6. Fabrics and fabrics

Although many people believe they are allergic to wool, this material in its pure state does not cause allergies.

What happens, in this case, is that the texture causes irritations that can be confused with an allergy.

Instead, the textile materials that cause allergies are those derived from formaldehyde resins.

This material is one of the basic components of elastic, waterproof, wrinkle and shrinks garments.

Symptoms of formaldehyde allergy are burns, hives, and swelling.

If you experience these symptoms, try changing your clothes for cotton, polyester, nylon or formaldehyde-free acrylics.

Sometimes, when the allergy is mild, the symptoms diminish or disappear after washing the garment several times.

7. Cosmetics

Sudden changes in temperature, exposure to cold or the sun can also cause this.


Eczema manifests as a red, itchy, itchy lesion. The skin appears rough with fine vesicles and dander. In more chronic eczema, the skin thickens.

Some substances are more allergenic than others and are more likely to induce allergic manifestations.

The chromium contained in leather tanning products in particular or the nickel contained in costume jewelry, zippers or belts.

Multiple substances incorporated in washing products (shower gels, shampoo), household products or medicines (Peru balm, antibacterials or antibiotics).
