If you notice small red dots on your skin, understanding their cause is important for your health and peace of mind. These spots, sometimes called petechiae or cherry angiomas, may appear singly or in clusters. While often harmless, they can occasionally signal underlying conditions that require medical attention.
Common causes include allergic reactions, insect bites, skin infections, or minor trauma. Less common but more serious causes involve blood disorders, autoimmune diseases, or side effects from medications. Red dots may appear as tiny, flat or raised spots in shades of red, purple, or brown. In some cases, they are itchy or tender, especially if linked to inflammation or allergies.
Harmless conditions like cherry angiomas, heat rash, or folliculitis are frequent culprits. However, more serious issues such as cellulitis, vasculitis, or impetigo may need prompt medical treatment. Monitoring changes in size, number, or associated symptoms is essential.
While home remedies like cold compresses may help mild cases, persistent or worsening red dots should be checked by a doctor. Regular skin checks, sun protection, balanced nutrition, and good hygiene all contribute to prevention and overall skin health.
