What It Is:Cherry angiomas are benign growths of small blood vessels that appear as red or purple spots, typically on the torso or arms. They are common as people age.
Causes: Cherry angiomas are usually harmless and are thought to be a result of aging, genetics, or possibly even hormonal changes.
When to Seek Help: If a cherry angioma changes in size, shape, or color, or if it bleeds easily, it’s worth getting it checked by a dermatologist to rule out any other conditions.
3. Allergic Reactions: Red Dots or Rash
What It Is:Allergic reactions can cause red dots or a rash to appear on your skin. These may be itchy or irritated, and the dots can be raised or flat.
Causes: Allergies to food, medications, insect stings, or contact with certain substances (like poison ivy or certain fabrics) can trigger an allergic reaction. Conditions like hives can also present as red, raised spots.
When to Seek Help: If the rash is severe, if you have difficulty breathing, or if it’s accompanied by swelling of the face or throat, seek medical attention immediately as this could be a sign of a severe allergic reaction (anaphylaxis).
4. Heat Rash: Small Red Dots Caused by Sweating
What It Is:Heat rash (also called prickly heat) consists of small, red bumps or dots, often in areas where sweat has been trapped under the skin.
Causes: Heat rash occurs when sweat ducts become clogged, leading to irritation and the formation of red dots. It’s common in hot, humid conditions and in areas where skin rubs together, like the neck, back, or chest.
When to Seek Help: Heat rash usually goes away on its own once you cool down. However, if the rash becomes infected or doesn’t improve with cooling measures, it’s best to see a doctor.
