What causes rashes?

Contact dermatitis

Rashes can have a variety of causes, but one of the most prevalent is contact dermatitis. The skin can develop this kind of rash if it comes into direct contact with a foreign material that triggers an unfavourable reaction, which in turn causes the rash to appear. The rash that develops as a consequence may be itchy, red, or irritated.

The following are some of the potential triggers for contact dermatitis:

Cosmetics and toiletries Detergents and soaps for washing clothes Dyes used in clothing Chemicals found in rubber, elastic, or latex Poisonous plants like poison oak, poison ivy, and poison sumac

Taking drugs can also lead to skin irritation and rashes. They can come about as a result of the following:

  • a hypersensitivity reaction to the pharmaceutical
  • a negative reaction to the medicine that can occur
  • caused by the medication’s effect on photosensitivity

Other causes

The following are some more potential factors in the development of rashes:

  • The site of an insect bite, such as a fleabite, can occasionally become inflamed and develop into a rash. Because ticks are known to spread disease, getting bitten by one is cause for serious concern.
  • The most common type of eczema is called atopic dermatitis, and it appears as a rash on the skin. People who have asthma or allergies may be more likely to get this type of eczema. The rash is typically reddish, although it might be the same colour as the patient’s skin or even darker on those with darker skin tones. It has a scaly appearance and can be irritating at times.
  • Psoriasis is a common skin ailment that can lead to the development of a rash that is scaly, itchy, red, or purplish and can appear anywhere on the body, including the scalp, elbows, and joints.
  • A kind of eczema known as seborrheic eczema is one that most frequently manifests on the scalp and is characterised by redness, scaly patches, and dandruff. It is also possible for it to appear on the nose, brows, or ears. Cradle cap is the name given to the condition when it occurs on infants.
  • The inflammatory condition known as systemic lupus erythematosus can cause a rash that spreads to the cheeks and nose of the affected person. A “butterfly” rash, also called a malar rash, is the name given to this condition.
  • Rosacea is a persistent skin disorder that has no clear underlying cause. There are various subtypes of rosacea, but the symptoms of redness and rash on the face are consistent across the board.
  • The rash that is characteristic of ringworm is caused by a fungal infection known as ringworm. Both jock itch and athlete’s foot are caused by the same fungus, which also causes ringworm on the scalp and other parts of the body.
  • Skin irritation caused by diapers is very prevalent in newborns, babies, and toddlers. It is possible that prolonged contact with a moist diaper played a role in its development.
  • The skin condition known as scabies is caused by an infestation of microscopic mites that live on and burrow into the skin. It results in a rash that is rough and irritating.
  • Cellulitis is an inflammation of the skin that is caused by bacteria. It manifests itself most frequently as a crimson, swollen region that is both painful and sensitive to the touch. Cellulitis is an inflammation of the skin that can be caused by an infection that, if left untreated, can progress and become potentially fatal.

Causes of rashes in children

Rashes are a common side effect of many common childhood ailments, and children are especially susceptible to developing them:

  • The chickenpox rash is characterised by little blisters and itchy bumps that appear all over the body. The chickenpox virus is responsible for causing the rash.
  • The measles is an infectious respiratory disease caused by a virus that results in a rash that is characterised by raised, red bumps that are itchy.
  • An infection known as scarlet fever is caused by group A Streptococcus bacteria. These bacteria create a toxin, which results in a rash that looks like sandpaper and can be bright red or a skin tone colour.
  • Hand, foot, and mouth disease is a viral infection that can cause red lesions on the mouth as well as a rash on the hands and feet. In some cases, the disease can even spread from person to person.
  • The fifth disease is a viral infection that manifests as a rash that is red and flat, and it can appear anywhere on the body, including the torso, arms, and legs.
  • The Kawasaki disease is an uncommon but deadly condition that, in its early stages, manifests as a rash and a fever and has the potential to cause issues in the heart.
  • Impetigo is a bacterial illness that can spread from person to person and manifests as a rash that is crusty, itchy, and fluid-filled with yellow lesions on the affected area, such as the face, neck, or hands.

You should be able to treat most contact rashes, but the specific treatment will depend on the reason. If you want to reduce your level of discomfort and hasten the process of recovery, follow these guidelines:

  • Instead of using perfumed bar soaps, use cleansers that are light and gentle.
  • When bathing your skin and hair, opt for warm water rather than hot water because it is gentler.
  • Instead than rubbing the rash, pat it dry to remove excess moisture.
  • Allow the rash to get some air. It is best not to cover it up with clothing if at all feasible.
  • Put an end to using any recently purchased lotions or cosmetics, as they could be the cause of the rash.
  • The eczema-affected areas should be treated with a moisturising lotion that is odourless.
  • It is important to refrain from scratching the rash because doing so might make it worse and may even trigger an infection.
  • If the rash is highly irritating and causing discomfort, you can apply a hydrocortisone cream that is available over-the-counter (OTC) to the area that is afflicted. Calamine lotion can also be used to alleviate the itching and discomfort caused by chickenpox, poison ivy, and poison oak.
  • Take a bath in some oatmeal. The itching that is common with skin conditions like eczema and psoriasis may be relieved by this. The following is a description of how to prepare an oatmeal bath.
  • If you also have a rash on your scalp, you should use a shampoo designed to treat dandruff on a daily basis to clean your hair and scalp. Shampoos formulated to treat dandruff are typically sold at pharmacies, but if you have a really severe case, your physician may prescribe a more potent variety.

Over-the-counter (OTC) medications


Discuss your options for pain relief with a medical practitioner, who may suggest over-the-counter medications such as ibuprofen or acetaminophen to address the slight discomfort caused by the rash.

Because of the potential for adverse effects, you should avoid taking these medications for an extended period of time. Inquire with a qualified medical practitioner about the maximum safe dosage for you to consume for how long. If you have a history of stomach ulcers, liver illness, or renal disease, it is possible that you will not be able to take them.

When to see a healthcare professional about rashes

If the rash does not clear up after using home remedies, you should seek the advice of a qualified medical practitioner. You need to get in touch with them as well if, in addition to the rash, you’ve been suffering any other symptoms that make you think you might have an infection.

If you do not currently have a primary care provider, you can use the FindCare function on Healthline to locate a qualified medical practitioner in your area.

rash patient’s medical history diet most recent items or drugs used hygiene

Your doctor or other medical practitioner might also:

take your temperature and order the appropriate tests, such as an allergy test and a full blood count.

Conduct a skin biopsy, which entails removing a tiny sample of tissue from the skin for the purpose of analysis.

I would recommend that you get further evaluation from an expert, such as a dermatologist.

Your healthcare provider may also recommend medication or medicated lotion to alleviate the itching and discomfort caused by your rash. The vast majority of people can successfully manage their rashes with a combination of medical therapies and self-care at home.

What you can do now

If you develop a rash, consider the following advice:

  • To alleviate the discomfort caused by mild contact dermatitis, try several home treatments.
  • Determine what may have caused the rash in the first place and stay away from those things as much as you can.
  • If the rash does not clear up after trying home therapies, you should get in touch with a qualified medical practitioner. You need to get in touch with them as well if, in addition to the rash, you’ve been suffering any other symptoms that make you think you might have an infection.
  • Be sure to pay close attention to any therapies that your doctor recommends. If your rash does not improve after therapy or if it continues to grow worse, you should consult a medical expert.
