Sometimes you may notice small red dots on your skin, which can be a cause for concern. These red dots may be harmless, but sometimes they may indicate a health problem that needs attention. In this article, we will learn about the possible causes of red dots on the skin and how to deal with them.
1 Vasculitis (blood rash)
One of the common causes of red dots on the skin is inflammation of the small blood vessels, which occurs when blood leaks from the small blood vessels under the skin. This condition is known as blood rash, and is often the result of injury or excessive pressure on the skin. It may occur as a result of falls or minor injuries, and it may also appear in people who are exposed to excessive pressure for long periods, such as people with high blood pressure or borderline syndrome.
2 Skin allergies
A rash resulting from allergies can appear in the form of red dots. This allergy may be the result of the skin’s reaction to foods, medications, or chemicals found in cosmetics or detergents. Contact with allergens can cause skin irritation and the appearance of red dots, in addition to itching or swelling.
3 Acne
Acne can sometimes appear as small red dots, especially in the inflammatory stages of the disease. Acne occurs when the skin pores become clogged with oils and dead skin, causing inflammation in the hair follicles. Acne can also be accompanied by pimples or blackheads.
