Red dots on the skin can appear for various reasons. While some may disappear on their own, others may require appropriate treatment. Common causes of red spots include allergic reactions, acne scars, vascular birthmarks, angiomas, protein overproduction, heat rash, insect bites, leaking capillaries, and autoimmune conditions.
Petechiae and Purpura
These tiny red dots are caused by damaged blood vessels or capillaries. They can result from stress, coughing, or certain medications. While typically harmless, they can sometimes indicate underlying platelet disorders.
Cherry Angiomas
These small, raised, bright red bumps are caused by an overgrowth of blood vessels and are usually harmless. They tend to appear with age.
Heat Rash
Heat rash occurs when sweat becomes trapped in sweat ducts, leading to itchy, red dots on the skin.
Allergic Reactions
Redness can also appear as a result of an allergic reaction to food, substances, medications, or insect stings and bites.
Folliculitis
Folliculitis is the inflammation of hair follicles, typically caused by bacterial or fungal infections. It results in red, pus-filled dots on the skin that can be uncomfortable.
Cellulitis
Cellulitis is a bacterial skin infection that causes redness and swelling. It often requires medical attention and treatment with antibiotics.
Impetigo
Impetigo is a contagious bacterial infection, primarily affecting children. It is characterized by red sores that open, ooze fluid, and eventually form a crust.
Vasculitis
Vasculitis is a condition associated with autoimmune disorders or infections, leading to inflammation of blood vessels.
Hemangiomas
Hemangiomas are birthmarks caused by abnormal growth of blood vessels. While generally harmless, they may occasionally require medical intervention.
