Is your skin suddenly red and itchy? It could be Contact Dermatitis! Shall we talk about this?

Your skin suddenly turns red and itches unbearably, doesn't it? Maybe with blisters. You may not be able to figure out what's causing this. Most of the time, this happens when we touch something, that is, when we come into contact with something. Today we are talking about a condition called 'Contact Dermatitis'. There is nothing to worry about, this is something that happens to many people. Let's see what it is, how it happens, and how we can protect ourselves.

What is Contact Dermatitis?

Simply put, contact dermatitis is when our skin reacts to something in the environment and causes an itchy rash . "Dermatitis" is the medical term for inflammation or swelling of the skin. You get this condition when you come into contact with something that is harmful to your skin, that is, irritating it . It could be a chemical, a plant, a metal, or anything else.

Are there types of contact dermatitis?

Yes, there are mainly two types.

1. Allergic Contact Dermatitis

What happens is that your body reacts to something it doesn't like, that is, an allergy . Think about it, some people get red and itchy skin when they wear jewelry that contains nickel. That's how it is. Common allergens are:

  • The types of metals found in some jewelry (like nickel).
  • Some cosmetic products.
  • Perfumes `(Fragrances)`.
  • Some preservatives.

In this case, symptoms may appear several days after contact with the allergen. This means that they may not appear immediately .

2. Irritant Contact Dermatitis

This is when the skin comes into contact with something that directly damages it, that is, an irritant, and a painful rash develops quickly. This comes on more quickly than the allergic type. It usually happens like this:

  • Soap powder, some types of harsh soaps (Detergents, Soaps).
  • Cleaning materials `(Cleaners)`.
  • Types of acids `(Acid)`.

Most of the time, we see this type of irritant contact dermatitis, rather than the allergic type.

Who can develop Contact Dermatitis?

This can actually happen to anyone of any age . It can happen to a small baby, a young person, or an adult. Sometimes it can happen after touching something once, and other times it can happen gradually over time with continued use of something.

However, people in certain professions are at a slightly higher risk of developing this condition because they are often exposed to chemicals or allergens that are harmful to the skin. For example:

  • Construction workers (because of things like cement, paint).
  • Florists (due to the sap of some plants).
  • Food processors (due to some vegetables, fruits, spices).
  • Hairdressers (due to dyes and chemicals).
  • Healthcare workers (due to frequent hand washing, certain medications).
  • Plumbers, cleaning workers (due to toxic cleaners).
  • Mechanics (due to grease and oils).
  • Painters (due to paints, solvents).

How common is this condition?

Contact dermatitis is actually quite common . There are so many things around us that can be harmful to the skin, right? If your skin is sensitive, or if you have other skin conditions, this condition can occur frequently.

How does Contact Dermatitis affect my body?

This is when your skin becomes irritated, like a rash. It can appear anywhere on your body. It usually appears as a red, itchy, and sometimes painful area. It can last from a few days to two to three weeks. However, the best thing is to find out what caused it and avoid touching it, and it will get better quickly .

What does contact dermatitis look like? What are the symptoms?

In this case, the symptoms you may see on your skin are:

  • The skin may appear red, perhaps purple , or darker than your natural skin color.
  • It may be swollen, raised, and may even look like a beehive .
  • It may appear as a cluster of small blisters .
  • Sometimes these blisters can ooze fluid or something like pus .
  • It may feel like a burning or stinging sensation along with the pain .
  • The skin may become flaky and dry .
  • Always scratching .

Important: If you scratch this itchy area frequently, your skin may become damaged. If it does, germs can get into it and cause an infection. The area may then become red, crust over, become more painful, and pus may collect.

Where on the body do these symptoms occur most often?

These symptoms can appear anywhere your skin has come into contact with the offending substance, but the most common areas are:

  • Face, neck and scalp.
  • Lips, eyelids, cheeks.
  • Hands, fingers, upper arms.
  • Genital areas (male and female).
  • Armpits.
  • Feet and legs.

What are the causes of Contact Dermatitis?

As mentioned earlier, the main cause of this is skin contact with an allergen or irritant .

Think about it, when you touch something you don't like on your skin, your body's immune system reacts to it. When you see your skin swelling and turning red, it means your white blood cells are working against that allergen or irritant. That's what causes those itchy bumps. An irritant can cause symptoms within minutes. An allergen can take hours, or even days, to develop symptoms.

Common causes of Allergic Contact Dermatitis:

  • Some plants or plant parts (e.g., Poison Ivy).
  • Skin care products with fragrances .
  • Metals , especially nickel.
  • Some medications (e.g. some antibiotics).
  • Preservatives or chemicals .

Common causes of Irritant Contact Dermatitis:

  • Types of acids `(Acids)`.
  • Cleaning products.
  • Body fluids , for example urine (like diaper rash in young babies) and saliva.
  • Some plants (e.g. poinsettia, hot peppers).
  • Hair dyes .
  • Nail polish remover or other solvents.
  • Types of paints and varnishes.
  • Soaps or detergents .
  • Resins, plastics and epoxies .

Is Contact Dermatitis contagious?

Here's a question that many people ask. Imagine that you touched a plant like `(Poison Ivy)`. If you then touch someone else's skin without washing your hands, the allergen from that plant can be transferred to that person. If they are also allergic to it, they can also get sick. However, contact dermatitis itself is not directly contagious. Your body only reacts to what you touched, and not everyone reacts the same way.

Can Contact Dermatitis spread to other parts of the body?

Yes, sometimes it can. This is especially true in allergic contact dermatitis. How do you know? After you touch an allergen, it spreads to other parts of your body before you realize you've touched it. Or, several parts of your body are exposed to the allergen at the same time, and symptoms start appearing in all of them. If you notice that the rash is spreading to other parts of your body, it's best to see a doctor right away and get treatment.

How to recognize contact dermatitis?

A doctor diagnoses this condition by taking a complete medical history, performing a physical examination, and carefully examining your symptoms.

There is no specific test to find the exact cause of irritant contact dermatitis. But your doctor will ask you questions about your environment, things you have recently touched, the location of the rash, and its size. Questions like these may be asked:

  • How long has this plague been around?
  • Have you made any changes to your skin care routine?
  • Have you touched any new plants, substances, or chemicals?
  • Are you constantly exposed to irritants or chemicals?

If allergic contact dermatitis is suspected, your doctor may suggest a patch test . This involves placing small, sticker-like patches on your skin (usually your back). These patches contain common allergens. After about two days, the patches are removed to see which substance your skin reacts to.

Very rarely, a doctor may take a skin sample (skin culture or biopsy) and examine it under a microscope.

How is Contact Dermatitis treated?

The treatments for this are very similar for both types (allergic and irritant).

  • Avoidance: This is the most important thing. Once you have identified the cause of the problem, you should avoid touching or being exposed to it as much as possible.
  • Taking medication to reduce swelling and itching: This can be done by prescribing anti-itch creams, antihistamines, corticosteroid creams (a type of steroid) or sometimes oral steroid pills (e.g., prednisone). Immunosuppressant medications are rarely prescribed.

Can Contact Dermatitis cause complications?

Apart from the usual sting, serious complications are very rare, but they can happen if you have a severe allergy to something. These can include:

  • Hives: Itchy, red/dark patches of skin that appear raised in places.
  • Swelling (Angioedema): A part of the skin becomes more swollen than the day before. This is swelling that occurs deep under the skin.
  • Anaphylaxis: This is the most severe allergic reaction . It causes swelling of the airways, making it difficult to breathe, and can be life-threatening.

Anaphylaxis is a medical emergency that requires immediate treatment! If you experience difficulty breathing, swelling of the lips or mouth, go to the nearest hospital immediately or call 911. This condition can be controlled by giving an injection of epinephrine immediately. It is important for people with severe allergies to always carry an epinephrine injection, such as an EpiPen®, with them.

What should I do if I develop contact dermatitis at work?

If you are exposed to chemicals or allergens that are harmful to your skin at work and you have this condition, ask your employer for a chemical safety data sheet for the chemicals. Take it with you to your doctor. It can help determine the cause of your symptoms.

How long does contact dermatitis last?

Even with treatment, it can take several weeks for these lesions to completely disappear. However, symptoms such as itching may subside within a few days of starting treatment, although the skin lesions may still be present. Minor contact dermatitis, if the cause is avoided, may resolve in a few days without additional treatment. If you have these symptoms, it is best to seek medical advice.

What should I expect if I have contact dermatitis?

There is no permanent cure for this. That is, if your body has reacted to an allergen or irritant once, it is likely to react the same way if you come into contact with that thing again. The best thing to do is to avoid it .

Many people who develop this condition due to workplace exposure can find ways to reduce their exposure. A doctor can give you advice on how to deal with this condition.

How to prevent contact dermatitis?

You can protect yourself from this situation by doing these things:

  • Avoid touching things you know you are allergic to .
  • Choose fragrance-free moisturizers .
  • Use fragrance-free or dye-free soaps and cleansers .
  • If you touch something you know is harmful, wash your hands and skin thoroughly immediately .

When should I see a doctor?

See a doctor if your skin rash looks like this:

  • If you have blisters .
  • If it gets better for a while and then reappears .
  • If it looks infected (red, hot, swollen).
  • If there is pain .
  • If you are constantly scratching unbearably .
  • If treatment does not improve within a week .

When should I go to the Emergency Department (ETU) ?

If you have difficulty breathing , or if your lips or mouth swell , go to the nearest hospital emergency room immediately or call 911! This could be a condition called anaphylaxis.

What questions should I ask the doctor?

If you have symptoms of contact dermatitis, you may want to ask questions like these when talking to a doctor:

  • What is causing these spots on my skin?
  • Should I get an allergy test?
  • What can I do to prevent contact dermatitis?
  • What is the best treatment for this?
  • What is the best treatment for this pain and itching?
  • What cleansers and moisturizers do you recommend that you can get at the pharmacy?
  • What are the signs of complications I should look out for?

What is the difference between Contact Dermatitis and Herpes?

Although both contact dermatitis and herpes can occur in similar areas of the body, they are very different. Herpes is a sexually transmitted viral infection and is spread from person to person through contact. Contact dermatitis is not an infection, and it is not contagious.

What is the difference between Contact Dermatitis and Atopic Dermatitis or Eczema?

Allergic Contact Dermatitis is related to a condition called atopic dermatitis, or eczema. Both can occur in people with allergies. Contact dermatitis occurs when your skin comes into contact with something that is harmful to it. That is, it is caused by something from outside. Atopic Dermatitis , or eczema, occurs in people with allergies, but it is often not caused by a specific thing; it can be caused by something from within.

Can tea tree oil treat contact dermatitis?

Tea tree oil has some antibacterial properties, so it may help with skin reactions like contact dermatitis. However, if you have symptoms of contact dermatitis, do not use essential oils like tea tree oil without consulting a doctor. Applying something new to your skin at this time can make the condition worse and make it worse.

Summary and things to remember

So, contact dermatitis is an itchy rash that occurs when your skin reacts to something in your environment. A doctor can help you figure out what's causing your skin to react, and talk to you about ways to avoid it in your environment. If you're exposed to a chemical or other substance in your workplace, your doctor can give you advice, and your organization can help you create a safe work environment to reduce your risk of future skin problems.

Remember, if you experience any unusual skin irritation, itching, or pain, it is wise to seek medical advice without ignoring it.
