Skin Tags in Children: When They Appear and What To Do

Skin tags in children are almost always harmless. They are benign, soft, flesh-colored growths that form where skin rubs against skin or clothing. They are not contagious, not cancerous, and do not indicate a serious health problem in most cases. If you have noticed one on your child, the most important thing to know first is that watchful waiting is the standard approach for pediatric skin tags. At-home plasma pen removal is not appropriate for children. This article explains when skin tags appear in children, why they form, how to tell them apart from other growths, and what the right next step looks like.

For the broader picture on skin tags including causes, locations, and all treatment options, see our complete skin tag guide. This article is focused on children specifically.

When do skin tags first appear in children

Skin tags are much more common in adults than in children, but they do occur in kids, particularly in two age windows.

Infancy through toddlerhood

Skin tags can appear at birth or develop in the first few years of life, most often in areas where skin folds press together: the neck, armpits, and groin. These early-life skin tags are often related to friction and the way soft infant skin creases during movement and sleep. Many resolve on their own over months or years as the child grows and friction patterns change.

Puberty

As hormone levels shift during adolescence, the skin becomes more susceptible to benign growth formation. Friction remains the main mechanical trigger, but hormonal changes in insulin sensitivity and androgen levels can also make skin tags more likely to form in kids aged 10 to 16. Overweight children are more prone to skin tags at any age, because excess body weight increases skin-fold friction. For older children and teenagers, the pattern is closer to adult skin tags: once formed, they tend to stay unless removed.

What causes skin tags in children

The root cause of skin tags in children is the same as in adults: friction. When skin rubs repeatedly against skin or clothing, the mechanical stress can trigger a small outgrowth of tissue. The most common locations in children reflect where friction concentrates: the neck, armpits, eyelids, groin, and the underside of the arms. For more on how friction specifically drives skin tag formation, see our guide on skin tags from friction and chafing.

Friction alone does not fully explain why some children develop skin tags and others don't. Other contributing factors include:

Genetics and body weight

Genetics. Skin tag tendency runs in families. If a parent has multiple skin tags, their children have a higher likelihood of developing them.

Body weight. Higher body weight creates more skin-fold friction. Children who are overweight or obese develop skin tags at higher rates, for the same reason adults do. The connection is mechanical, not metabolic, in most children.

External friction and hormonal changes

Friction from clothing or equipment. Tight collars, stiff clothing seams, backpack straps, and sports equipment that rubs against the neck or armpits can all initiate a skin tag in susceptible skin.

Hormonal changes during puberty. Shifts in androgen and insulin levels during adolescence can influence benign skin growth formation. This is why many teenagers notice their first skin tags around ages 12 to 15. The entity referenced in pediatric dermatology for this growth type is the acrochordon, a benign skin condition catalogued in the NIH MedlinePlus health library.

Are skin tags in children dangerous

No. A typical skin tag on a child is benign. It does not become cancerous. It does not spread to other areas of the body. It does not infect adjacent skin.

That said, there are a few circumstances that should prompt a dermatologist visit rather than watchful waiting.

Per the American Academy of Dermatology, any growth on a child that changes appearance, bleeds, or causes discomfort should be evaluated by a physician, not treated at home. The reason the last point matters: several benign growths in children can look similar to skin tags at first glance. Warts, molluscum contagiosum, and soft fibromas can all be mistaken for skin tags. Getting an uncertain growth evaluated by a pediatric dermatologist or pediatrician costs little and removes the uncertainty entirely.

How to tell a skin tag from other growths on your child

A true skin tag has a consistent visual profile that helps distinguish it from other common pediatric growths.

Skin tag profile

Soft, smooth, skin-colored or slightly darker than surrounding skin, attached by a narrow stalk or flat base, moves freely when touched, does not bleed from light contact, not painful when gently pressed.

Common look-alikes

Wart: rough, firm texture. Often has a cauliflower-like or dotted surface. Warts do not move freely. They can appear anywhere, including the hands and feet, and they are caused by the human papillomavirus (HPV). A skin tag is not caused by HPV.

Molluscum contagiosum: small, round, pearlescent bumps with a central dimple. Often appear in clusters. Contagious, particularly in school-age children.

Soft fibroma: very similar to a skin tag but typically larger and firmer. Often arises in adolescence or early adulthood.

If the growth matches the skin tag description above (soft, smooth, stalk-attached, skin-colored, moves freely), it is most likely a skin tag. If you are uncertain at all, a single visit to your child's pediatrician settles the question quickly and cleanly. Per the Mayo Clinic, benign skin growths are common in children and are generally identified on physical examination without further testing.

A skin tag moves freely. A wart does not. That single test rules out the most common mix-up.

What to do about a skin tag on your child

For most children with skin tags, the right answer is watchful waiting. Benign skin tags in young children often diminish over time as the child grows and the friction pattern that caused them changes. Treating a growth that will resolve on its own introduces risk without benefit.

When clinical removal is appropriate

If the skin tag is consistently irritated by clothing, is in a location the child scratches or picks at, or is causing the child social distress, removal becomes a reasonable conversation to have with a pediatrician or pediatric dermatologist. Clinical options for children include snip excision (a quick clip at the base under local anesthetic) or cryotherapy (freezing). Both are fast, well-tolerated by children, and appropriate for in-office pediatric care.

Why at-home plasma pen removal is not appropriate for children

At-home plasma pen removal is not appropriate for children. The plasma pen delivers controlled plasma energy to tissue. That mechanism requires the user to hold the pen precisely against a small target, select the correct power setting for the lesion size, and hold still throughout the treatment. Children, particularly young children, cannot reliably hold still enough for safe at-home plasma pen use. The power settings on consumer devices are calibrated for adult skin and adult pain tolerance. The aftercare compliance required (no picking the scab, SPF 50 during Week 2 to 3) is difficult to ensure in children. For all of these reasons, at-home plasma pen removal is an adult tool, and pediatric skin tags belong in a clinical setting when removal is the decision.

If you have your own skin tags and are exploring at-home options, the OcuraLife Plasma Pen is designed for that. It is not the right tool for a child's skin tag. For adults, a closely related question is why skin tags form in the armpits (the most common adult location) and whether changes in body weight affect them.

Aftercare for adult skin tags: the treatment timeline

For adults who are ready to address their own skin tags at home, the OcuraLife Plasma Pen delivers a predictable healing sequence. Understanding this timeline also explains why pediatric compliance is the core barrier to at-home use in children.

The bottom line

Skin tags in children are benign, not contagious, and not dangerous in the vast majority of cases. They form from friction and are more common in overweight children, infants with prominent skin folds, and teenagers going through hormonal changes. Watchful waiting is the right first response for most families. If the growth is changing, bleeding, or painful, a pediatrician should look at it. At-home plasma pen removal is not appropriate for children and belongs in a clinical setting when removal is the chosen path.
