Allergy and skin – when the immune system overreacts

Allergies are among the most common chronic illnesses in Central Europe. Whether it's pollen, pet dander, house dust, or certain foods – allergic reactions manifest not only in the respiratory tract or eyes, but also very frequently on the skin. Itching, redness, and eczema are a burden for many sufferers in their daily lives.

But how exactly do allergies affect the skin? And what concrete steps can be taken to alleviate symptoms and strengthen the skin?

What is an allergy?

An allergy is a misdirected reaction of the immune system to substances that are actually harmless. The body mistakenly classifies the substance – the allergen – as a threat and triggers inflammatory processes. Immediate-type allergies are particularly common, in which symptoms appear within minutes of contact with the allergen.

Typical skin symptoms of allergies

The skin is one of the first organs to react to allergic stimuli. Typical symptoms include:

• Redness, itching, feeling of tightness
• Dry, scaly or weeping areas
• Blisters, welts or eczema

These reactions can be localized – for example, on the forearms after contact with animal hair – or spread to larger areas of skin.

Why skin is so sensitive

The skin is not just a protective layer, but an active immune organ. Specialized immune cells lie directly beneath the surface, releasing inflammatory messengers like histamine upon contact with allergens. This leads to redness, swelling, itching, and often also to a loss of the skin's natural barrier.

What helps with allergic skin?

Avoiding contact

Knowing your personal triggers allows you to react accordingly. This includes, for example, frequently washing clothes and textiles, avoiding fragrances, or wearing gloves when handling animals.

Acute care

Non-irritating sprays, gels or roll-ons with soothing ingredients can quickly relieve the skin – ideally immediately after contact.

Strengthen the skin barrier

• Gentle cleansing without alcohol, perfume or harsh surfactants
• Regular re-oiling with lipids or skin-soothing minerals
• Daily care to retain moisture and maintain the natural protective function.

Use cortisone selectively

Cortisone may be necessary for severe allergic eczema, but should not be used long-term. For mild to moderate reactions, natural alternatives are often sufficient for symptomatic relief.

Everyday skincare: These rituals help

Take a lukewarm shower

Hot water dries out the skin and causes further irritation. Short, lukewarm showers (maximum ten minutes) and immediate application of cream help to maintain the skin barrier.

Drink enough fluids

Drinking at least 1.5 to 2 liters of water per day promotes hydration of the skin from within and supports natural regeneration.

Reduce stress

Stress affects the immune system and can worsen allergic reactions. Relaxation techniques such as mindfulness, breathing exercises, or moderate exercise have been proven to help.

Healthy sleep

The skin regenerates during sleep. Regularly sleeping seven to eight hours supports the natural renewal of skin cells.

Allergen-free environment

Smooth floors instead of carpets, regular washing of textiles, HEPA filters in vacuum cleaners and, if necessary, air purifiers help to reduce allergen exposure – especially for pet hair or house dust allergies.

For acute irritations: targeted relief with Quellmed Acute Roller

For allergic itching – for example after contact with animal hair or irritants – the Quellmed Acute Roller has proven to be a natural, practical aid.

It contains highly mineralized spring water from Nienburg/Weser with minerals such as magnesium, sodium, calcium, bromide, and iodide, known for their skin-soothing and anti-inflammatory properties.

Thanks to its hygienic roll-on application, it is also suitable for use on the go, for example during a walk, in the office or after contact with animals.
