There is a common internet claim that petroleum jelly can remove skin tags, but there is no good scientific evidence that petroleum jelly alone will shrink, dry out, or remove a skin tag.
Vaseline and other petroleum jellies are primarily moisturizers that protect the skin barrier.
What Petroleum Jelly Can Do
Moisturize irritated skin
Reduce friction around a skin tag
Protect the surrounding skin if the tag rubs against clothing
Simple Petroleum Jelly Skin Protection Method
Ingredients
Petroleum jelly
Mild soap and water
Steps
1. Wash the area gently and pat dry.
2. Apply a thin layer of petroleum jelly to the skin tag and surrounding skin.
3. Repeat 1–2 times daily if the area becomes irritated from friction.
This may make the area more comfortable, but it is unlikely to remove the skin tag.
What Not to Do
Avoid:
Cutting off a skin tag yourself
Tying it off with thread unless instructed by a healthcare professional
Applying harsh chemicals, acids, or undiluted essential oils
Using DIY remedies that cause burning or skin damage
These methods can lead to:
Infection
Bleeding
Scarring
Misidentification of a growth that is not actually a skin tag
Safe Medical Removal Options
A healthcare professional can remove skin tags using methods such as:
Freezing (cryotherapy)
Snipping with sterile instruments
Cauterization (heat)
These methods are generally faster, more effective, and safer than home remedies.
When to Get It Checked
See a healthcare professional if a skin growth:
Changes color
Bleeds easily
Becomes painful
Grows rapidly
Has an unusual appearance
This is important because not every skin growth is a skin tag.
If you’d like, I can also explain how to identify a typical skin tag versus other common skin growths and when removal is medically recommended.
