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.
