Red Dots on Your Skin: Causes and What They Could Mean

The article discusses various reasons why red dots may appear on the skin, ranging from harmless to more serious conditions:

Some of the most common reasons which lead to the red spots are allergic reactions, acne residual mark, vascular birthmarks, skin spots due to angiomas, protein overproduction, heat rash, insect bites, leaking capillaries, as well as autoimmune conditions.

1. Petechiae and Purpura:
   Tiny red dots resulting from damaged blood vessels or capillaries, possibly due to stress, coughing, or certain medications. While often harmless, they can sometimes indicate underlying platelet disorders.
2. Cherry Angiomas:
   Small, raised, bright red bumps caused by an overgrowth of blood vessels, generally harmless and more common with age.

1. Heat Rash:
   Occurs when sweat becomes trapped in sweat ducts, leading to itchy, red dots on the skin.
2. Allergic Reactions:
   Redness can result from allergic reactions to foods, substances, medications, or insect stings or bites.
3. Folliculitis:
   Inflammation of hair follicles due to bacterial or fungal infections, causing red, pus-filled dots that can be uncomfortable.
4. Cellulitis:
   A bacterial skin infection leading to redness and swelling, requiring medical attention and antibiotics.
5. Impetigo:
   A contagious bacterial infection, primarily in children, characterized by red sores that open, ooze fluid, and form a crust.
6. Vasculitis:
   Inflammation of blood vessels associated with autoimmune disorders or infections.
7. Hemangiomas:
   Birthmarks from abnormal blood vessel growth, usually harmless but occasionally needing medical intervention.
