Red dots on the skin are actually quite common and can have various causes. In case you find yourself in a similar situation, I’ve compiled a list of some common causes of red dots below. It’s important to note that red dots can come in different sizes, shapes, and colors, and their meanings can vary as well. While some are harmless, others might indicate underlying medical conditions.
Here are some common causes of red dots on the skin:
1. Petechiae and Purpura
These are tiny red dots that appear on the skin due to damaged blood vessels or capillaries. They can be caused by stress, coughing, or certain medications. Although they are usually harmless, they can sometimes indicate underlying platelet disorders.
2. Cherry Angiomas
These are small, raised, bright red bumps that result from an overgrowth of blood vessels. Don’t worry, cherry angiomas are generally harmless and tend to be more common as we age.
3. Heat Rash
Heat rash is a simple and common condition that occurs when sweat becomes trapped in sweat ducts. It can cause itchy, red dots to appear on the skin.
4. Allergic Reactions
If you have an allergic reaction to food, substances, medications, or insect stings or bites, it can lead to redness and an itchy rash on the skin.
5. Folliculitis
Folliculitis is an inflammation of the hair follicles, usually caused by bacterial or fungal infections. It can result in red, pus-filled dots on the skin that can be uncomfortable.
