Skin tags have a frustrating habit of appearing exactly where you don’t want them.
Around the neck.
Under the arms.
Beneath the breasts.
Along the groin.
Sometimes around the eyelids.
They may catch on necklaces, rub against clothing, or simply become more noticeable as the years pass. And because skin tags become increasingly common with age, it’s no surprise that generations of home remedies have promised an easy way to make them disappear.
One of the most popular combines just two ingredients:
baking soda and castor oil.
The mixture is often described as an old-fashioned method that gradually dries a skin tag until it shrinks or falls away.
But before covering a spot with homemade paste, there’s one important question:
Is it definitely a skin tag?
What Exactly Is a Skin Tag?
A skin tag, medically called an acrochordon, is a small, soft, benign growth of skin.
Many hang from the surface on a tiny stalk.
They’re especially common in areas where skin rubs against skin or clothing.
Most are harmless.
And unless they’re irritated or cosmetically bothersome, they generally don’t need to be removed at all.
The challenge is that not every little bump is a skin tag.
Moles, warts, seborrheic keratoses and other skin growths can sometimes look surprisingly similar.
That’s why identifying the spot correctly matters before trying to remove anything yourself.
Why Baking Soda and Castor Oil Became Popular
The recipe usually involves mixing baking soda with enough castor oil to form a thick paste.
Castor oil contains a fatty acid called ricinoleic acid and works well as an emollient, helping soften and condition the skin.
Baking soda, meanwhile, is alkaline and mildly abrasive.
Some traditional-remedy enthusiasts believe repeatedly covering a skin tag with this paste causes it to dry and eventually detach.
It’s an appealing theory.
Unfortunately, there’s no strong clinical evidence showing that baking soda and castor oil reliably remove skin tags.
And repeatedly irritating a growth isn’t the same thing as safely removing it.
Why Castor Oil Alone May Make the Area Feel Better
There’s nothing particularly strange about using castor oil on ordinary intact skin.
It’s thick and occlusive and can make dry skin feel softer.
If a skin tag is surrounded by dry, irritated skin from friction, a small amount of moisturizer may make the area more comfortable.
But moisturizing the surrounding skin doesn’t destroy the skin tag itself.
That’s an important distinction.
Baking Soda Is the More Questionable Ingredient
Baking soda has a high pH compared with the naturally mildly acidic surface of healthy skin.
Repeated application can therefore irritate the skin barrier.
That becomes especially relevant because skin tags often occur in sensitive areas—the neck, armpits, groin, and beneath skin folds.
Those aren’t areas where you want to create a chemical irritation.
If a homemade paste starts burning, stinging, or turning the surrounding skin raw, that’s not evidence that it’s “working.”
It’s irritation.
Don’t Try to Scrub a Skin Tag Away
Baking soda is also mildly abrasive.
That can be useful for cleaning a sink.
It’s much less useful when you’re dealing with a piece of living tissue.
Scrubbing a skin tag can cause:
Bleeding.
Inflammation.
Pain.
Skin damage.
Potential infection.
A skin tag isn’t dead skin sitting on the surface waiting to be exfoliated.
It’s attached to your skin and has its own blood supply.
What About Leaving the Paste on Overnight?
This is another common version of the remedy.
People apply castor oil and baking soda, cover the area with a bandage, and leave everything in place overnight.
Occlusion can increase the effect of substances placed on the skin.
Unfortunately, that can also increase irritation.
Repeatedly trapping an alkaline paste against mature or sensitive skin for many hours isn’t something I’d recommend.
Especially not before you’ve confirmed what the growth actually is.
Never Try This Around the Eyes
Skin tags frequently develop around the eyelids.
That doesn’t make them good candidates for home removal.
Keep baking soda, castor oil mixtures, acids, essential oils, and commercial skin-tag chemicals away from the eyes.
A dermatologist or appropriately trained eye specialist can determine the safest approach for an eyelid growth.
Your eyesight is worth considerably more than avoiding a quick appointment.
The Same Goes for Sensitive Areas
Avoid DIY removal on growths around the genitals, anus, nipples, or other highly sensitive locations.
Those areas are easily injured and some conditions can be mistaken for ordinary skin tags.
Home treatment makes much less sense when professional removal is usually quick.
Don’t Cut Them Off Yourself
It looks tempting.
A tiny stalk.
A pair of scissors.
Two seconds.
Problem solved.
Except you don’t know how much it will bleed, whether the instrument is appropriately sterile, or whether the growth you’ve removed was actually a skin tag.
The same applies to burning, aggressively twisting, or repeatedly traumatizing a growth.
There are safer options.
What About Tying Dental Floss Around It?
Another old remedy involves tying thread or dental floss tightly around the base to cut off the blood supply.
Small skin tags may eventually fall away when their blood supply is interrupted.
But doing this yourself can cause pain, bleeding, infection, or damage to surrounding tissue.
And again, it assumes you’ve correctly diagnosed the growth.
That assumption is the weak point behind many DIY removal methods.
Why Skin Tags Become More Common With Age
Skin tags can occur at almost any age, but they’re especially common in adulthood.
Friction appears to play a role, which helps explain why they favor skin folds.
They’re also seen more frequently in people with overweight or obesity and can be associated with insulin resistance and metabolic conditions.
Having a few skin tags doesn’t automatically mean you have diabetes.
But if numerous new tags appear alongside other metabolic risk factors, discussing blood sugar with your healthcare provider may be worthwhile.
When a “Skin Tag” Deserves a Closer Look
A typical skin tag is usually soft, flesh-colored or slightly darker, and relatively stable.
Get an unfamiliar growth checked if it:
Changes rapidly.
Bleeds without obvious irritation.
Develops unusual colors.
Becomes persistently painful.
Forms an ulcer.
Looks very different from your other spots.
Continues growing.
Those changes don’t automatically mean something serious.
They simply mean guessing at home isn’t the best strategy.
How Doctors Actually Remove Skin Tags
Professional removal is usually straightforward.
Depending on the tag’s size and location, a clinician may remove it by:
Snipping it with sterile instruments.
Freezing it with liquid nitrogen.
Using electrosurgery or another controlled procedure.
The appropriate method depends on the individual growth.
For a small uncomplicated skin tag, the entire procedure can be surprisingly quick.
And you leave knowing the correct structure was treated.
What If You Don’t Want It Removed?
Then leave it alone.
A harmless skin tag doesn’t require treatment simply because it exists.
If friction is the main problem, reducing rubbing may help.
Choose softer clothing.
Avoid necklaces that constantly catch the area.
Keep skin folds clean and dry.
Use a gentle moisturizer if surrounding skin becomes irritated.
Sometimes the safest skin-tag treatment is no treatment whatsoever.
Can You Prevent New Skin Tags?
There’s no guaranteed method.
Genetics, aging, skin friction, body composition, and metabolic factors can all contribute.
But maintaining a healthy body weight and reducing repeated friction in skin folds may help in some cases.
And if you have many skin tags along with risk factors for insulin resistance, routine health checks become more useful than repeatedly treating individual tags.
The skin sometimes gives us clues about what’s happening elsewhere in the body.
If You Already Tried the Baking-Soda Mixture
Don’t panic.
If your skin looks completely normal, simply stop if the mixture is irritating or isn’t accomplishing anything.
If the area becomes red or sore, gently wash away the product and avoid additional irritating ingredients while the skin recovers.
Don’t follow baking soda with vinegar, lemon juice, garlic, or another viral remedy.
Your skin doesn’t need a second experiment to repair the first one.
Castor Oil Still Has a Place
Castor oil doesn’t need to remove skin tags to be useful.
A small amount can work as an emollient on dry, intact skin.
It can help reduce that rough, tight feeling associated with dryness.
So if you bought a bottle specifically for the skin-tag recipe, it doesn’t have to go to waste.
Use it for what oils do particularly well:
softening dry skin.
The Bottom Line
The baking-soda-and-castor-oil remedy has circulated for years because it’s inexpensive, simple, and sounds plausible.
A typical homemade version combines baking soda with enough castor oil to create a thick paste.
But there isn’t good evidence that this mixture reliably or safely removes skin tags, and repeated baking-soda exposure can irritate the surrounding skin.
Most importantly, don’t try to destroy a growth until you’re confident it’s actually a harmless skin tag.
If a tag bothers you, professional removal is generally quick and allows the spot to be properly identified first.
And if it doesn’t bother you?
You may not need to do anything at all.
Sometimes the smartest old-fashioned skin remedy is knowing which little imperfections are perfectly safe to leave alone.
