Skin allergies can be triggered by different reasons and require special attention and medical consultation.
Before talking about the main types and symptoms, it is worth explaining that the skin is the largest organ in the body, and due to its protective role, it is often affected by allergies — an inflammatory reaction caused by sensitivity to some stimulus, which can be diverse, as we will see below. Even though it is a condition that in most cases does not cause problems, depending on the type, more intense and emergency care may be necessary.
According to the World Health Organization (WHO), 40% of the world’s population suffers from frequent allergic conditions, which is why in this article we will talk a little more about the subject, showing the main types of skin allergies, the main causes, symptoms and possible treatments.

What are the types of skin allergies?
As mentioned, there are several triggers for skin allergies and we will show you the main ones, providing information on what causes them and possible treatments.
1. Hives
Hives are an allergic skin reaction caused by insect bites, allergies or temperature changes, for example, which manifests itself through red spots that cause itching and swelling. It can be controlled by avoiding exposure to the factors that trigger it and, in some cases, through the use of certain medications, such as anti-allergy medications .
In general, the symptoms of hives last up to 24 hours, disappearing without leaving marks or scars. However, the spots may reappear on other parts of the body, remaining for a few weeks, and this type of hives is called chronic hives.
2. Angioedema
Angioedema is edema ( swelling ) that affects deep layers of the skin and may be associated with hives. This swelling is deforming and can last for hours to days. The most affected areas of the body are the eyelids and lips, but it can occur anywhere on the body.
The most feared location is the larynx (glottis edema), which when affected can cause asphyxiation and lead to death if not promptly treated. The most common causes of angioedema are allergies to food, medications and insect stings.
Treatment is carried out according to the type of angioedema. In allergic angioedema, the triggering agent must be removed and in crises the use of antihistamines, corticosteroids and adrenaline is indicated, depending on the location and intensity of the edema. Other types of angioedema do not respond to the use of medications used to treat allergies and specific medications are required to treat crises.
3. Nervous allergy
Nervous allergy is a type of dermatitis that can arise after stressful situations or emotional problems. It can be characterized by eczema-like lesions, that is, red, rough patches, sometimes with small blisters and with itching as the main symptom.
Allergies and irritations can occur anywhere on the body. Stress can cause seborrhea/dandruff, redness and itching on the sides of the nose, central region of the face, eyebrows, chin and behind the ears and back.
3. Contact dermatitis
Contact dermatitis , also known as contact eczema, is an inflammation of the skin caused by direct contact with a particular substance. The rash may be very itchy, limited to a specific area, and usually has well-defined borders.
The main causes are from contact with cosmetics such as soaps, creams, deodorants, lotions, sunscreens, perfumes, or with metals such as rings, wristwatches, earrings, bracelets and other accessories. Irritant contact dermatitis occurs due to the use of substances that can irritate the skin, such as acids, and which are present in chemical products used in cleaning, and also in solvents, such as acetone.
Contact dermatitis can be allergic, arising as a response of the immune system and taking several months to appear, or it can be irritant contact dermatitis, caused by contact with chemical substances and appearing immediately or shortly after the patient’s exposure.
5. Atopic dermatitis
Atopic dermatitis is a chronic skin disease that mainly appears in childhood. Its causes are still unknown, but may be linked to defects in the immune system. It mainly appears in the folds of the body, such as the knees and elbows. It can cause intense itching and usually disappears during adulthood.
This skin inflammation is allergic in origin and is not contagious, and the most affected areas vary according to age. Although there is no cure, atopic dermatitis can be treated with anti-inflammatory medications in ointment or tablets, and with skin hydration.
6. Mosquito bite
One of the main causes of allergies, mosquito bites generate inflammatory reactions due to the anticoagulant action of the insect’s saliva. Most allergic reactions are mild, but severe cases require emergency medical assistance.
7. Food allergy
Food allergies are also one of the most common allergies and can be quite serious if not diagnosed in time. The initial symptoms are skin rashes, hives, nausea and diarrhea. The greatest danger is when an anaphylactic reaction occurs, which can cause severe inflammation in the throat, obstructing breathing and even causing death.
The foods most likely to cause this illness are peanuts, almonds, walnuts, eggs, cashews and crustaceans in general. Diagnosis is made through skin and blood tests, which detect the presence of specific antibodies. Treatment is with antihistamines, corticosteroids and adrenaline, in the case of anaphylactic shock.
What is the best antihistamine for skin allergies?
The best treatment for skin allergies depends on the case and should be recommended by a doctor . More common and less severe cases can be treated with soothing hypoallergenic products and lotions with substances such as chamomile or lavender. When the first symptoms appear, it is important to wash the area thoroughly with water and soap with a neutral pH.
More severe cases are commonly treated with antihistamines such as desloratadine and ebastine, or with corticosteroids such as hydrocortisone and mometasone.
Hydration is essential to combat allergies, as healthy skin creates a stronger protective skin barrier, which prevents inflammation from reaching deeper layers of the skin.
How long does an allergic skin reaction last?
Allergic skin reactions usually appear within minutes of contact with the allergen (the substance causing the inflammation). In some cases, however, inflammation can take several hours or up to three days to develop, so it is important to remember which substance or food caused the reaction.
Skin allergies can persist for days, weeks or months. In cases of longer duration, it is important to see a dermatologist or allergist.
Never self-medicate when it comes to skin allergies. Be aware that contact with the wrong substances can trigger a series of consequences depending on the situation. Before doing anything, do your research, consult a doctor and assess your condition so that you can treat the condition.
