The red spots on the skin can be a concern for some people. However, the causes can range from allergic reactions to some more severe than other infections. It is necessary to pay attention to the shape, size, and how long they last on the skin and can even ooze some liquid. However, it does not have to do with skin cancer or any malignancy most of the time. At FastlyHealwe will show you some of the causes of red spots on the skin and how to treat them.

Types of red spots on the skin

Depending on the pathology, the red spots can appear in different ways:

  • Erythema: It appears as a flat red spot and is usually caused by excess blood flow. They tend to go away on their own.
  • Papules: a type of lesion that appears small but bulging and with well-defined edges.
  • Vascular: they are characterized by secreting fluid and are common in children. Some may be elevated and pink or purplish and require special treatment.


It usually appears as red spots that cause itching, inflammation, and hives that can become enlarged, usually due to allergic reactions. When we contact an allergen, our body releases histamines into the bloodstream, which causes inflammation and itching. The factors that trigger these symptoms are:

  • Insect bites.
  • Food allergies include fish, eggs, milk, shellfish, and nuts.
  • Animal dander, especially that of cats.
  • Poland.
  • Some medications
  • Stress.
  • Autoimmune diseases like lupus.
  • Excessive sweating

Generally, it is easy to treat since it is only necessary to identify the allergen and avoid contact. You should also avoid hot showers, wear tight clothing, and the doctor will suggest an antihistamine cream. If the allergic reaction is severe, you will need an adrenaline injection.

Contagious diseases

The red spots on the skin may also occur for some infectious diseases such as chickenpox, measles, rubella, or mononucleosis. They are small, itchy red spots on the skin, blister-shaped spots that usually appear first on the face and spread to the rest of the body, they usually have flu-like symptoms, but once the infection is treated, the red spots will disappear. They are usually very contagious diseases, so specific isolation and rest measures are required.


It is also known as the strawberry marks, and they are benign tumors formed by an abnormal growth of the blood vessels. They are usually birthmarks that can appear during the first six months of life, and their size is variable. Sometimes, they present lumps, and they tend to decrease by one year of age and disappear entirely between 5 and 6 years.

Because they occur temporarily, some hemangiomas do not need treatment if they are painful, change the size, or affect their appearance. For these cases, we can find the following treatments:

  • Use of cosmetics to hide marks.
  • Cryotherapy, in which liquid nitrogen is used to freeze the affected area.
  • Removal.
  • Laser surgery


Dermatopathies include a wide variety of skin diseases. Different red spots such as pimples occur and can lead to scaling and other lesions that are not infectious or contagious. Among the most common dermopathies we have:

They generally have itchy neck, face, and body fold, flaking in the scalp, oily skin, and even hair loss. The treatment will be determined by the cause of the red spots on the skin, and your doctor may recommend some soap and shampoo with specific formulas and ointments.

Other causes

Other causes of less concern are:

  • Bad nutrition
  • Hair weakness, especially when we start to age or suffer from stress.
  • Diseases related to blood clotting.
  • Hits


  • Consult your doctor before any red spot that you present on your skin.
  • Pay attention to bumpy red spots
  • Eat foods rich in vitamin C and E
  • Increase your intake of green leafy vegetables like broccoli, spinach, and chard.
