A rapid immune system overreaction to apparently harmless substances – this is the basic idea of an allergic reaction. In most cases, it happens due to pollen, food, or insect stings, causing rash, mild itching, and sneezing, and sometimes anaphylaxis (lethal!).
Here, we talk about key reasons behind skin allergies, and the testing and long-term care plan for individuals.
The immune system naturally builds antibodies (protective proteins) against foreign substances, but in cases of allergies, the antibodies mark some specific substances as concerning and harmful for bodies, which are ideally not.
Allergic reactions vary among individuals, and most of the allergies are not curable, but proper treatment and care can relieve the symptoms.
Learn about some key skin allergies and their symptoms and triggers, allergy diagnosis testing, and long-term care plan, before you seek help from a private dermatologist (Dermatologue privé).
Some Common Types of Skin Allergies
Here are some common types of skin allergies you should know about before taking any preventive measures or visiting a private dermatologist (Dermatologue privé).
Contact Dermatitis
If you touch something allergic, contact dermatitis is triggered. However, the triggers may vary for various skin types, but the most common ones are detergents and soaps, nickel jewellery, skincare and cosmetic products, poison oak, sumac or poison ivy, and latex gloves.
Symptoms
- Swelling and persistent redness.
- Blistering, itchy rash.
- Peeling, dry, or cracked skin
Hives (Urticaria)
Due to certain medications, like aspirin and antibiotics, foods, like shellfish, nuts, and dairy, insect bites or stings, and extreme temperatures, hives occur.
Symptoms
- Raised wheals or welts.
- Intense itching
- Blanching
- Angioedema (deep swelling around the lips and eyes)
Eczema (Atopic Dermatitis)
A chronic skin disease, eczema, is related to bronchial asthma and dermatitis. Remember, the issues may start during infancy and may persist during adulthood as well.
Symptoms
- Itchy, dry, and scaly patches.
- Redness and inflammation
- Oozing blisters.
Psoriasis
Triggered by infections, allergens, and stress, psoriasis leads to inflammation and scaling due to the skin cells’ overproduction.
Symptoms
- Cracked, dry, bleeding skin
- Red, thick patches with scales
- Burning and itching sensation.
| Types of Allergens | Allergy Triggers |
| Environmental Allergens | Mould, pollen, pet dander. |
| Chemical Irritants | Preservatives, fragrances, and harsh soaps. |
| Food Allergies | Gluten, dairy, and nuts |
| Medications | NSAIDs, antibiotics, and tropical creams. |
| Insect Stings | Wasp or bee strings |
| Climate | Extreme cold, heat, or humidity. |

Diagnosis of Skin Allergies via Medical Testing
Here are some of the major diagnostic tests conducted by private dermatologists to determine skin issues and take remedial steps.
Skin Prick Test
Known as a puncture or scratch test, Skin Prick Tests immediately detect allergic responses to 50+ different allergens, including fungus, pollen, animal dander, and dust mites.
For adults, the test is conducted on the forearm, while for children, experts perform it on the upper back. Doctors carefully use lancets to prick the skin surface (not painful, don’t worry).
But before the test, professionals clean the site of pricking with alcohol, and the skin area is marked to administer multiple allergens.
Any other chemicals on the skin?
Yes, a private dermatologist may use histamine or glycerine. If your skin does not respond to histamine (any skin reaction), the allergy test might be incorrect. However, if your skin reacts to glycerine, you have sensitive skin.
Skin Injection Tests
A popular intradermal skin test, where dermatologists use an injection to administer the allergen into your skin.
After 15 minutes, they check the skin surface to detect allergic reactions. It is mostly recommended for insect venom or penicillin allergy.
Patch Test
Mostly recommended in contact dermatitis, where patients experience skin inflammation due to allergens.
During the test, dermatologists apply 20-30 patches on the skin, and in most cases, the allergens are perfumes, preservatives, resins, medications, and hair colours.
Experts ask to keep the patches for 48 hours, since these tests diagnose delayed allergic reactions. During this period, you are now allowed to engage in any physical activities or bathing.
Long-Term Care and Management
So, how to manage allergic reactions? Are medicinal treatments enough, or do you need to be more careful about some other things? Let’s find out.
Avoid Allergic Triggers
This is the most effective strategy to get rid of unwanted allergic issues. Avoid restricted foods and drinks, and use hypoallergenic or fragrance-free products.
Moisturising
Use a clinically-approved moisturiser (hypoallergenic) on your skin, since it helps maintain a skin barrier.
Topical Treatments and Medication
Corticosteroid creams and ointments are the best options to reduce constant itching and inflammation. However, oral antihistamines, like Benadryl, reduce swelling and itching.
Note: Immunotherapy helps desensitise the immune system by exposing it to specific allergens, via tablets or shots. It trains the body against the allergens, while the entire process decreases allergy-causing antibodies and increases protective antibodies (IgG4). It reduces symptoms and induces long-term immune tolerance.
Final Thoughts
The allergic triggers are either natural components or available in our everyday surroundings. So, before the issues escalate, make sure you seek professional help and follow your medication. Before the tests, ask the experts about the test impacts and whether there are any side effects or not. Know your issues and preventive measures, while long-term care can help you strategically deal with allergic reactions.
