Red dots on the skin can arise from various causes, some of which resolve on their own, while others may need medical attention. Common reasons include allergic reactions, acne scars, vascular birthmarks, angiomas, heat rash, insect bites, and autoimmune conditions.

Petechiae and purpura result from damaged blood vessels, often harmless but sometimes linked to platelet disorders. Cherry angiomas are small, raised red bumps caused by blood vessel overgrowth, frequently appearing in older adults. Heat rash occurs when sweat becomes trapped, leading to itchy red spots. Skin redness can also stem from allergic reactions, bacterial infections like folliculitis or cellulitis, or conditions such as impetigo, a contagious skin infection. Other potential causes include vasculitis, which is inflammation of the blood vessels, and hemangiomas, a type of birthmark.

Home remedies like aloe vera gel, coconut oil, or dandelion root tea may provide relief. However, if red spots worsen, spread, or change in appearance, seeking medical advice is recommended. A balanced diet and proper skincare can also help maintain healthy skin.
