Small red dots on the skin can be a common occurrence and are usually harmless. However, they can sometimes indicate a more serious underlying condition. Here are 10 common causes of small red dots on the skin:
1. Petechiae: These pinpoint-sized red dots are caused by broken capillaries and can be a sign of a blood disorder.
2. Cherry angiomas: These are small red moles that are usually benign but can be removed if they become bothersome.
3. Heat rash: Also known as prickly heat, this condition occurs when sweat gets trapped under the skin, causing red bumps.
4. Allergic reaction: Small red dots can be a sign of an allergic reaction to food, medication, or skincare products.
5. Eczema: This chronic skin condition can cause red, itchy patches of skin that may have small red dots.
6. Psoriasis: Another chronic skin condition, psoriasis can cause red, scaly patches of skin with small red dots.
7. Rosacea: This common skin condition causes redness and small red bumps on the face.
8. Contact dermatitis: Small red dots on the skin can be a sign of contact dermatitis, which is caused by an irritant coming into contact with the skin.
9. Insect bites: Mosquito bites, flea bites, and bedbug bites can all cause small red dots on the skin.
10. Skin cancer: In rare cases, small red dots on the skin can be a sign of skin cancer, such as basal cell carcinoma or squamous cell carcinoma.
If you notice small red dots on your skin that are persistent, increasing in number, or accompanied by other symptoms, it's important to see a doctor for a proper diagnosis and treatment.
