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 small, raised, bright red bumps are a result from an overgrowth of blood vessels and are generally harmless. They usually appear at old age.
3. Heat Rash
Heat rash occurs when sweat becomes trapped in sweat ducts and causes itchy, red dots to appear on the skin.
4. Allergic Reactions
Redness can also occur in case of an allergic reaction to food, substances, medications, or insect stings or bites.
