Warts are one of the most common skin conditions, affecting millions of people worldwide. They are caused by certain strains of the human papillomavirus (HPV), which enters the skin through tiny cuts or breaks. Although contagious, most warts are harmless and can often disappear on their own or be treated effectively.

There are several different types of warts, including common warts found on the hands, plantar warts on the soles of the feet, flat warts on the face and legs, and filiform warts that usually appear around the mouth, nose, or eyes. Each type has its own appearance and may require a different treatment approach.

Many warts can be treated with over-the-counter products containing salicylic acid or by using cryotherapy, which freezes the wart. In some cases, a dermatologist may recommend stronger treatments if the wart is painful, spreading, or doesn’t respond to home care.

While most warts are not dangerous, it’s important to see a doctor if a growth changes color, bleeds, becomes very painful, or if you’re unsure whether it’s actually a wart. Early diagnosis can help rule out more serious skin conditions and ensure the most effective treatment.
