It is identified as swelling, rashes, blister-like breakouts, itching and burning sensations on the skin. When a person is affected by skin allergies, dermatologists need to identify the exact type, cause of it and thereafter prescribe a suitable treatment mode. Herein we provide details of the five most common forms of skin allergies.
5 Types of Skin Allergies
Atopic dermatitis is the most common form of skin allergies, characterized by extremely itchy skin, swelling, blister formation, pimples with crusts as well as scaling. This form of skin allergy is believed to be hereditary and affects people with asthma or hayfever.Common triggers include very dry weather, reactions to certain foods or even a reaction to soaps and detergents. This rash affects the skin of the elbows, behind the legs, back, chest and even face.
Atopic dermatitis is generally harmless, though constant itching and scratching can break the skin and worsen the condition. To diagnose, your dermatologist might recommend a skin patch testing. To control and prevent atopic dermatitis, it is recommended that you stay away from potential allergens, avoid itching of the affected area, use mild and fragrance-free soaps, wear comfortable clothes and avoid extreme temperatures.
Also known as hives, these appear as red welt-like outbreaks on the skin surface. Common triggers of hives include allergic reactions to foods like peanuts, nuts, shellfish, specific medicines, insect bites and infections like cold, viral infections and even urinary tract infections. This skin condition could last from several minutes to hours (acute urticaria) or even months (chronic urticaria).
Hives generally affect hands, legs and back. When welts or swelling appear around the eyes and lips, they are called angioedema. As with other forms of allergies, urticaria is worsened by scratching, wearing very tight or uncomfortable clothes, changes in temperatures and exposure to the sun. If these outbreaks are accompanied by dizziness, respiratory problems, swelling of the face or tongue, or flushing, immediate medical attention must be sought.
Primary allergens for this condition include use of certain cosmetics, hair dyes, lotions, topical medications or even certain metals. Its appearance is limited to the point of contact with the allergen, typically areas around the eyes, hands, neck and feet.
Contact dermatitis appears as itchy blisters that also render a burning sensation. Dermatologists use patch tests to determine the exact cause of this allergy.
This is one of the more severe forms of skin allergy that is incurable. No particular trigger has been identified for this, though this allergy affects areas that have high sebum secretion. This allergy appears red and scaly and can also have pus formations. The areas affected by this allergy include scalp, ear canals, eyelids, cheeks, armpits, chest and upper back.
The diagnosis of seborrheic dermatitis is generally performed under microscope. This skin allergy is generally treated by using products that contain antifungal antibiotics, selenium sulfide or zinc pyrithione.
This skin allergy normally affects people with dry, itchy skin and appears as coin-shaped breakouts on the arms, legs, back and buttocks. Triggers include extreme weather conditions, use of harsh soaps, skin infection caused by bacteria, or even a reaction to isotretinoin, a medicine generally prescribed to treat acne.
This is a chronic form of skin allergy and medications can only prevent future outbreaks. Mild outbreaks can be controlled by the use of topical cortisone creams. In case of severe conditions, your doctor might prescribe steroidal creams or even oral medications.No matter what type your skin allergy is, proper diagnosis and treatment is essential. Once the cause is identified, it is important to avoid that particular trigger so that the problem remains controlled.
