Red dots on the skin are quite common and can stem from a variety of sources. Here’s a simplified rundown of the possible causes:
Petechiae and Purpura: These “minuscule red dots emerge as a result of damaged blood vessels” and can be brought about by stress or medications. They might signal platelet disorders.
Cherry Angiomas: Small, elevated, vivid red bumps that are “typically harmless” and become more prevalent with advancing age.
Heat Rash: Happens when sweat gets lodged in the ducts, giving rise to red, itchy dots.
Allergic Reactions: Can be set off by food, substances, or insect bites, leading to redness and itchy rashes.
