Introduction

Skin tags are extremely common, harmless skin growths that appear on the neck, underarms, eyelids, groin, or other friction-prone areas. Many people worry when they notice a skin tag for the first time and wonder, “Are skin tags contagious?”

Are Skin Tags Contagious?

No — skin tags are NOT contagious.
They do not spread from one person to another through touch, sharing items, or any form of contact. Skin tags are non-infectious and non-cancerous growths.

You cannot “catch” skin tags from someone else, and your own skin tags do not spread on the body due to touching or rubbing.

What Causes Skin Tags?

Although they look unusual, skin tags usually form due to:

1. Friction

Skin rubbing against skin or clothing—common in the neck, underarms, and groin.

2. Hormonal Changes

Pregnancy and hormonal fluctuations can increase the chances of skin tags.

3. Genetics

If your family members have skin tags, you may develop them too.

4. Obesity

Overweight individuals tend to have more friction folds, leading to skin tags.

5. Diabetes & Insulin Resistance

Higher insulin levels can contribute to multiple skin tags.

6. Aging

Skin tags become more common after age 40.

Symptoms of Skin Tags

Skin tags are usually:

• Small, soft, flesh-colored growths

• Painless

• Connected by a thin stalk

• Non-cancerous

• Not itchy unless irritated by clothing or jewelry

Can Skin Tags Spread on Their Own?

Skin tags may increase in number, but they don’t spread through infection.
More skin tags usually appear due to:

• Weight gain

• More friction

• Hormonal changes

• Insulin resistance

It’s a natural process, not a contagious one.

How Are Skin Tags Treated?

Skin tags do not require treatment unless they bother you for cosmetic or physical reasons.

Common removal methods include:

1. Cryotherapy (Freezing)

The tag is frozen and falls off.

2. Electrocautery

Burning the tag with controlled heat.

3. Radiofrequency or Laser Removal

Quick, painless, and commonly used in clinics.

4. Surgical Removal

Cutting the tag using sterile tools.

Never attempt to cut or tie skin tags at home. It may cause infection or scarring.

Can Skin Tags Be Prevented?

You can reduce chances of developing new skin tags by:

• Maintaining healthy weight

• Reducing friction in skin folds

• Wearing loose, breathable clothing

• Managing diabetes and insulin levels

• Following good skincare hygiene
