The reason why red dots appear on the skin can be various, and while some of them go away on their own, some require a suitable treatment. 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 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.
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.Allergic Reactions Redness can also occur in case of an allergic reaction to food, substances, medications, or insect stings or bites.
Folliculitis Folliculitis is an inflammation of the hair follicles, usually caused by bacterial or fungal infections resulting in red, pus-filled dots on the skin that can be uncomfortable.Cellulitis Cellulitis is a bacterial skin infection that causes redness and swelling of the skin. It usually requires medical attention and treatment with antibiotics. 7. Impetigo Impetigo is a contagious bacterial infection that primarily affects children and is characterized by red sores that open, ooze fluid, and later form a crust. 8. Vasculitis Vasculitis is a condition associated with autoimmune disorders or infections that involves inflammation of blood vessels. 9. Hemangiomas Hemangiomas are birthmarks that result from abnormal growth of blood vessels. While they are generally harmless, occasional medical intervention may be necessary. Home remedies which help the prevention of spreading and getting rid of the red dots include some of the most widely used herbs and plants.
