Skin rash and allergies: how to soothe the skin?

Itching, eczema, red patches… Skin rashes often come from an allergy and can affect people at any age. The allergy can be caused by contact with an allergen or by ingestion. Follow our tips to soothe itching and make pimples and red patches disappear quickly. Choose our anti-blemish routine to help you keep your skin healthy.

How does a rash appear?

Symptoms of a skin allergy can vary from person to person. But there are two common forms:

  • Allergic contact eczema : When you come into contact with an allergen, your body protects itself with different reactions such as dry skin , red blistered patches or scabs. Don't panic! These rashes disappear after a few days without leaving any scars.

  • Hives : This is the fastest-acting form of skin allergy where you quickly find yourself covered in raised red patches. Hives appear only 15 to 30 minutes after exposure and disappear within a few hours.

What are the different types of skin rashes?

Depending on the cause, skin rashes can appear in very different forms: redness, plaques, angioedema , blisters, bumps, scales, furrows, vesicles, pustules, scabs, etc. This phenomenon can spread to the entire body or remain isolated. The spread of lesions can be rapid or very slow. It is therefore important to have them examined in order to obtain appropriate treatment.

What causes skin rashes?

The causes of a skin allergy or rash can be many and of various kinds.

Infections

In other cases, the rash may be a manifestation of an infection:

  • Bacterial like impetigo

  • Viral like chickenpox or shingles

  • Fungal like candidiasis

  • Parasitic like scabies

Chronic inflammatory skin diseases

A rash can be a symptom of chronic inflammatory skin diseases such as psoriasis or atopic dermatitis , otherwise known as eczema .

Heat and cold

Certain physical factors such as heat and cold can cause a rash to appear on the skin. Generally not serious, it disappears spontaneously when exposure stops within a few hours or days.

The sun

This is another physical factor. Your skin reacts to the sun's UV rays, causing a rash.

The different possible allergens

It is not just contact skin allergies that can cause rashes. Many allergens can trigger a skin allergy. In order to better choose the most suitable treatment, you need to know the precise cause of your allergy. Otherwise, you may experience a chronic condition.

Pimples, red patches and skin lesions can be caused by:

  • A contact allergy : creams, household products and chemical substances or even textile products.

  • Food allergy : Many cases of sudden skin rashes are caused by a food that is not tolerated. This is often the case in babies and young children.

  • A drug allergy : usually caused by an antibiotic, a drug allergy can also come from a simple painkiller.

  • Animal hair allergy : Animal hair such as cats and dogs can cause skin rashes.

It should be noted that allergens such as pollen rarely cause a skin rash. Symptoms are frequently conjunctivitis and allergic rhinitis.

How to calm an allergic reaction on the skin?

To calm skin rashes such as pimples and red patches, usually accompanied by itching , you should avoid any contact with the product or allergen causing the allergic reaction. Also avoid scratching yourself as this can make the lesions worse. If the infected area becomes oozing, healing can take many days. Then, always remember to consult a doctor to follow the appropriate treatment. This may consist of a cream, ointment or oil to apply as well as an antihistamine medication .

In the meantime, you can apply a compress soaked in cold water to the lesions to soothe the itching. Be careful, an allergic reaction should never be taken lightly, since in some cases it can lead to more serious symptoms such as:

  • Fever

  • Headaches

  • Dizziness

  • Diarrhea

  • Vomiting

  • Difficulties with the respiratory tract

How to identify allergens?

The immune system defends the body against all external aggressions and foreign substances. But in some people, the immune system overreacts. When faced with certain normally harmless substances, it triggers an inappropriate defense reaction: this is the appearance of an allergic rash .

In case of an allergic reaction, it is recommended to contact a dermatologist or allergist. The diagnosis of skin allergies is first made on the basis of a clinical examination and a complete interview. This initial assessment is sometimes sufficient to identify the substance or agent responsible for the allergic skin reaction.

If the allergen is not identified, the doctor can carry out an allergy assessment , with skin tests: drops of each allergen to be tested are placed on the skin in order to observe the reactions. In some cases, these tests are supplemented by a blood test, with measurement of IgE (immunoglobulin E antibodies) specific to certain allergens. A prescription treatment based on medication and anti-inflammatories can then be prescribed.

How to take care of your skin after a skin allergy?

Rashes tend to dry out the skin. So, it is important to moisturize it well on a daily basis. That's not all, you must take care of your pimpled skin so that it regenerates quickly once the allergy has passed.
