Finding a new bump or growth on your skin can be startling, especially when you are already keeping a close, proactive eye on changes to your skin and circulation (like those purple blotches we discussed!).
The good news? The vast majority of warts are completely harmless. However, because you appreciate the science behind how the body works and prefer simple, age-old home remedies, understanding exactly what a wart is—and what it isn't—is your best tool for handling them safely.
Here is everything you need to know about the 6 types of warts, how to treat them at home, and when to call the doctor.
🔬 The Science: What Exactly is a Wart?
Before we look at the types, it helps to know what causes them. Warts are not a sign of aging, and they aren't caused by touching frogs! They are caused by the Human Papillomavirus (HPV).
When this virus enters the top layer of your skin (usually through a tiny scratch or cut), it causes the skin cells to multiply rapidly. This overproduction of keratin (the hard protein that makes up your skin, hair, and nails) creates the rough, hard bump we call a wart. Because they are viral, they can be contagious, which is why you should never pick at them!
🔍 The 6 Types of Warts
1. Common Warts (Verruca Vulgaris)
- Where they appear: Most often on the fingers, hands, and around the nails.
- Signs & Symptoms: They are firm, raised, and have a rough, cauliflower-like surface. They are usually flesh-colored, white, or pink. If you look closely, you might see tiny black dots in the center—these are often called "wart seeds," but they are actually tiny, clotted blood vessels!
2. Plantar Warts
