Have you ever noticed red dots on your skin and wondered what could be causing them? Red spots can come up for a variety of reasons, ranging from simple and harmless to more serious conditions. Understanding the potential causes can help you determine if or when it’s time to seek medical attention. Here are 11 reasons why you might have red dots on your skin:
1. Contact Dermatitis
Your red spots may be the result of contact dermatitis, which is triggered by an exposure to irritating substances or allergens. Symptoms include an itchy rash with bumps, swelling, and flaky skin. Learning to identify and avoid the triggering substances is key to managing this condition.1
2. Cherry Angiomas
Cherry angiomas are characterized by round, red or purple spots on your skin, which are caused by enlarged blood vessels. Common in adults aged 30 and older, these growths are typically benign but can be removed if they bleed or cause any concerns.
3. Swimmer’s Itch (Cercarial Dermatitis)
Swimmer’s itch is caused by parasitic infection after being exposed to contaminated water, which then leads to itchy, red rashes (hence the name). Topical steroids and antihistamines can help with the symptoms, and antibiotics are available for persistent cases.
4. Heat Rash (Miliaria)
A common cause of red dots on your skin is heat rash, medically known as miliaria (not malaria). Heat rash is when sweat glands get blocked, resulting in small, red, prickly bumps on the skin. They’re often itchy or uncomfortable and typically appear in areas where sweat accumulates, such as the armpits, chest, or groin.2
5. Drug Rash
Drug rashes are an allergic reactions to medications and vary in severity from mild to potentially life-threatening. It’s very important to be able to identify and discontinuing using the offending medication, and medical intervention is needed in severe cases.

8. Blood Spots (Purpura)
Blood spots, AKA purpura, occur when small blood vessels burst under your skin, resulting in red or purple patches. While they aren’t always an indicator of a more serious condition, if it’s widespread there may be underlying issues that require a medical evaluation.
9. Ringworm (Tinea Corporis)
Ringworm, a fungal infection, manifests as red, circular rashes with raised edges (like a ring!). Highly contagious and super popular with the cool kids these days, it can spread via skin-to-skin contact or by touching contaminated objects. Antifungal treatments are usually effective in clearing it up.
10. Psoriasis
Psoriasis is an autoimmune disorder that leads to, you guessed it, red dots on your skin as well as plaques, often found on the elbows and knees. Psoriasis can be triggered by stress, infections, or environmental factors. So chill out and find somewhere calm to spend your time.
11. Lichen Planus
Lichen planus causes flat, itchy, purple spots on various parts of the body. This one is a little more interesting because the cause isn’t well understood, but there are treatment options available for it.
Bottom Line
While some red dots on your skin may resolve on their own or with simple remedies, others can and should require medical attention. Make sure you monitor the appearance of the spots and seek medical advice if you notice any concerning symptoms like a fever, swelling, or any difficulty breathing. Remember, your skin is a reflection of your overall health, and understanding its changes can help you stay informed and proactive in your overall well-being.
