Pregnancy is one of the most reliable triggers for skin-tag development and multiplication. The combination of elevated estrogen and progesterone, higher insulin levels, rapid weight gain, and new friction from the expanding body creates precisely the conditions that produce skin tags. Most pregnancy skin tags appear in the second and third trimester and are completely benign. The majority of options for removing them are postponed until after delivery and after breastfeeding ends.
For the full picture on skin tags in general, see our complete skin tags guide. This page covers the pregnancy and postpartum picture specifically.
Key takeaways
Pregnancy skin tags are extremely common and benign. Removal is usually deferred until after delivery and breastfeeding.
- Skin tags during pregnancy are common and peak in the second and third trimester.
- They are driven by hormonal changes, weight gain, and new friction from the changing body.
- A pregnancy skin tag is benign and requires no treatment unless it bleeds persistently, causes pain, or is in a location that makes daily life significantly harder.
- Most removal methods (plasma pen, cryotherapy, excision) are deferred until after delivery and the end of breastfeeding.
- Some pregnancy skin tags may partially shrink after delivery as hormones normalize, but most persist and will need to be removed if unwanted.
Why pregnancy causes skin tags
Skin tags form at the intersection of two factors: friction and biological amplification. Pregnancy delivers both simultaneously at an intensity that is hard to match outside of it.
Hormonal amplification
Estrogen and progesterone rise dramatically during pregnancy, and both affect fibroblast activity, the cells responsible for producing the connective tissue in skin. Elevated estrogen increases skin cell proliferation, and elevated progesterone relaxes the structural proteins in skin, making it more susceptible to friction-triggered growth. The result is that the same friction contact that might produce one skin tag in a non-pregnant adult produces several during pregnancy.
Insulin-like growth factor levels also rise during pregnancy as part of fetal development support, and higher growth factor activity directly promotes the kind of fibrous tissue proliferation that creates skin tags. This hormonal combination is why women who have never had a single skin tag before pregnancy can develop dozens during a single pregnancy.
Weight gain and new friction zones
Pregnancy weight gain creates new friction zones across the body: the expanding belly creates friction with clothing and with the upper thighs in ways that were not present before. The breasts enlarge rapidly, creating new under-breast contact and bra-band friction. The neck and armpits continue their pre-existing friction patterns. The combination of new friction zones and amplified hormonal response to friction is why skin tags during pregnancy tend to appear at multiple locations simultaneously.
Location pattern in pregnancy
Pregnancy skin tags most commonly appear on the neck, armpits, under the breasts, and along the bra band. In the third trimester, under-belly and upper-thigh tags become more common as the abdomen expands. The specific locations correspond directly to where the new friction zones are.
Pregnancy combines a dramatically amplified hormonal response to friction with a body that is rapidly creating new friction zones. Skin tags are an almost inevitable result for women with any baseline tendency toward them.
Are pregnancy skin tags dangerous?
No. Pregnancy skin tags are benign soft-tissue growths identical in structure to non-pregnancy skin tags. They contain no cancer risk, do not spread, and do not indicate any disease. According to NIH MedlinePlus, skin tags are common benign findings that are not associated with pregnancy complications and require no treatment unless desired.
The one exception that warrants medical attention: a growth that bleeds without contact, changes color, grows rapidly, or has an irregular border is not a typical skin tag and should be evaluated by a doctor during the pregnancy, not deferred. New pigmented or rapidly changing skin growths during pregnancy are in a different category from benign skin tags.
When to mention a skin growth to your OB or midwife
See your provider during the pregnancy (not after delivery) if any growth:
- Bleeds without being touched.
- Is dark brown, black, or has uneven pigment.
- Has changed size or shape in a short time.
- Is in an unusual location (genitals, perianal area) and you are not sure what it is.
Can you remove skin tags during pregnancy?
The standard guidance from dermatologists is to defer elective removal until after delivery and the end of breastfeeding. The reasons are practical rather than indicating a safety risk from removal itself.
Topical numbing creams, particularly those containing lidocaine, are absorbed through the skin and reach systemic circulation. Most lidocaine products are classified as Category B in pregnancy (no demonstrated fetal risk in animal studies, no controlled human studies), but the default recommendation is to minimize any topical medication use in pregnancy unless the benefit clearly outweighs the risk. For a completely elective cosmetic procedure, the benefit does not justify the exposure.
Cryotherapy, clinical excision, and plasma pen treatment are all classified as elective procedures and are generally deferred for the same reason: no pressing indication during pregnancy, and the tags are very likely to persist postpartum where they can be treated without any of the pregnancy-related constraints.
The exception: a tag that is in a location where it catches and bleeds repeatedly, causing pain or significant daily interference, can be evaluated by a dermatologist for removal during pregnancy. In that case, a dermatologist familiar with pregnancy skin care can assess the risk-benefit balance for that specific situation.
Do pregnancy skin tags go away after delivery?
Some do, partially. As estrogen and progesterone normalize in the weeks after delivery, some very small skin tags may shrink. A tag that was just starting to form during the third trimester may partially regress. However, the majority of skin tags that formed during pregnancy persist. They are stable fibrous tissue with an established blood supply, and hormone normalization alone does not dissolve them.
Most women find that the postpartum period is the right time to address the skin tags: the hormones have normalized, breastfeeding has ended, and the body is back to a more stable state. At that point, at-home removal with the plasma pen is an option.
Removing skin tags after pregnancy
Once you have delivered and finished breastfeeding, the OcuraLife Plasma Pen addresses postpartum skin tags at home in about five minutes per tag. A scab forms on Day 1, falls off on its own between Day 3 and Day 7, and the skin renews over Week 2 to Week 3. The numbing cream and aftercare protocol are the same as for any other skin-tag removal with the pen. For the full step-by-step, see our how to remove skin tags at home guide.
The postpartum period also tends to come with more skin tags from the new friction patterns of nursing (bra contact, arm-and-side contact while feeding) and from the weight that remains postpartum. Using the plasma pen on the existing cluster and addressing the new friction sources together gives the most complete result. See our skin tags from friction guide for the prevention side.

The bottom line
Skin tags during pregnancy are common, benign, and almost never a reason for concern. They appear because pregnancy delivers the perfect combination of hormonal amplification and new friction zones. Most are deferred for removal until after delivery and the end of breastfeeding. At that stage, the OcuraLife Plasma Pen handles postpartum skin tags at home in about five minutes per tag, with clear skin in two to three weeks. According to the American Academy of Dermatology, skin tags are among the most common benign skin findings and are safely removed at the patient's discretion once the pregnancy and breastfeeding period is complete.
