Skin Tags During Pregnancy: Why They Form and Gentle Care

If you've noticed a new, tiny flap of skin on your neck or under your arm this trimester, you're not imagining it and you're not alone. Skin tags during pregnancy are extremely common, entirely harmless, and one of the more forgettable ways a body changes to make room for a baby. Once you know why they show up, they tend to stop feeling like something to worry about.

A quick note before we get into it: this is general education, not medical advice for your specific pregnancy. Every pregnancy is different, so check with your OB, midwife, or dermatologist about any new skin growth you're unsure about.

What Exactly Is a Skin Tag?

A skin tag, known medically as an acrochordon, is a small, soft growth that hangs off the skin on a thin stalk. Most are just a few millimeters long, skin-colored or slightly darker, and soft enough to move gently between two fingers. They're sometimes mistaken for moles at a glance, but a mole tends to have a wider base and sits closer to the skin, while a skin tag hangs from a thin stalk.

Skin tags are not dangerous, and they don't turn into anything else. They're also common outside of pregnancy. Research collected in the National Library of Medicine's StatPearls reference puts the lifetime rate at roughly 50 to 60 percent of adults developing at least one. Having one, or several, says nothing about the health of your pregnancy.

Why Skin Tags Form During Pregnancy

Skin tags during pregnancy show up for a mix of reasons, and researchers haven't mapped the exact mechanism down to the last detail. Two factors get the most credit.

• Hormonal shifts. Rising levels of estrogen and progesterone are thought to speed up the growth of skin cells, which can encourage new tags to form.
• Friction. As your body changes shape, skin rubs against skin more often, especially in creases and folds. That steady rubbing is one of the more consistent triggers dermatology sources point to.

Weight changes over pregnancy add to both factors at once: more skin-on-skin contact in fold areas, layered on top of the same hormonal backdrop already driving cell growth. None of this means you did anything wrong. It's simply a common response to a body working overtime.

Where They Tend to Show Up

Skin tags favor spots where skin folds or rubs against itself, jewelry, or clothing. During pregnancy, that commonly means:

• The neck, especially where a necklace sits
• Underarms
• Under the breasts, particularly with a snug bra band
• The groin area
• Eyelids

Most people notice just one or two, though it's common to see several appear in the same general area over the second and third trimesters. They're one of several ordinary ways skin responds to a changing body, alongside things like stretch marks.

Gentle Care While You're Pregnant

There isn't much to actively do about a skin tag beyond simple, gentle care. A few habits can keep the area comfortable while you wait it out.

• Choose soft, breathable fabrics. Loose cotton against fold areas causes less rubbing than tight synthetic blends.
• Watch your jewelry and bra fit. A necklace that used to sit comfortably, or a bra band that's grown snug, is worth loosening or swapping for something softer.
• Keep the area clean and dry. A simple rinse with lukewarm water and a gentle pat dry is enough. Heavy scrubbing only adds more friction.
• Leave it alone. Picking, twisting, or snagging a skin tag can leave it sore or make it bleed.
• Cover a snag-prone one. If a tag keeps catching on a strap or collar, a soft adhesive bandage over the area stops it from getting caught again.

None of this needs to be complicated. The goal is simply reducing friction so the area stays comfortable, not making the tag disappear faster.

What Happens After Birth

For most people, this is temporary. As hormone levels come back down after birth, and after breastfeeding ends if you're nursing, many skin tags shrink or fall off on their own within a few months.

If one sticks around after your body has settled, that doesn't mean anything is wrong. It can simply be removed later, during a quick, in-office visit, if you'd like it gone. Removal is a provider procedure, not something to attempt yourself. Most providers are glad to wait until after pregnancy and breastfeeding to do it, unless a specific tag is bothering you sooner. Skip at-home removal kits, creams, or patches. There is no safe way to remove a skin tag on your own, so leave it to a professional when the time comes.

When to Check In With Your Provider

Most skin tags are nothing more than a cosmetic curiosity, but a few situations are worth a direct conversation with your OB, midwife, or dermatologist instead of guessing:

• The growth changes color, shape, or size
• It bleeds or becomes sore on its own, not just from snagging
• You're not actually sure it's a skin tag

Bring it up at your next prenatal visit if you notice any new skin changes, including a spot you can't quite identify. Mentioning new growths as they appear, rather than waiting, is a simple habit that keeps your provider in the loop and gives you a straight answer instead of a guess.

The Short Version

New skin tags during pregnancy are common, harmless, and driven by the same hormonal and physical shifts your body handles throughout the next nine months. Reduce friction where you can, leave the growth alone rather than picking at it, and expect most to fade on their own after you give birth. If anything looks different from a typical skin tag, your provider is the right person to ask.

Frequently Asked Questions

Why do I get skin tags when I'm pregnant?

Rising estrogen and progesterone are thought to speed up skin cell growth, while skin rubbing against itself in fold areas adds friction that can trigger a new tag. Weight changes during pregnancy make both factors more likely. Researchers haven't pinned down the exact mechanism, but hormones and friction are the two leading factors.

Can you remove skin tags while pregnant?

Yes, but it's usually a quick, in-office procedure your OB or dermatologist performs, not something you do yourself. Most providers prefer to wait until after birth and breastfeeding unless a tag is bothering you sooner. Skip at-home removal kits, creams, or patches. There's no safe way to remove a skin tag on your own.

Is it okay to pick at a skin tag?

No. Picking, twisting, or snagging a skin tag can leave it sore or make it bleed. If one keeps catching on a necklace, bra strap, or collar, cover it with a soft adhesive bandage instead so it stops getting caught. Leave any removal to your provider once you're ready.

Do pregnancy skin tags go away after birth?

For many people, yes. As hormone levels drop after birth, and after breastfeeding ends if you're nursing, skin tags often shrink or fall off on their own within a few months. Others stay the same size permanently. Either way, a persistent one can be removed later at a routine office visit if you'd like.
