Lots of Skin Tags Under the Armpit: What to Know

Skin tags are usually soft, flesh-coloured or slightly darker pieces of tissue that hang from a narrow base. The underarm is a common site because skin rubs against skin, clothing, or movement. Several can appear over time, and they may catch on a razor, become irritated, or twist and hurt.

Not every underarm bump is a skin tag. A wart, mole, cyst, inflamed follicle, or another growth can look similar. Rapid change, bleeding without rubbing, a firm fixed texture, or marked colour variation deserves an examination rather than home treatment.

Arrange a skin examination if the diagnosis is uncertain, the growths are multiplying quickly, or they interfere with shaving or clothing. Keep the area dry, choose clothing that reduces rubbing, and avoid tying off, cutting, or burning a tag yourself. These methods can cause bleeding, infection, scarring, or an incorrect diagnosis.

If removal is appropriate, a dermatologist may use a method suited to the size, base, and appearance of each growth. Options can include clinical snip removal, cryotherapy, or electrosurgery. Read about [Skin Tag Removal](/treatments/surgical-dermatology/skin-tag-removal/), [Cryotherapy (Lesion Removal)](/treatments/surgical-dermatology/cryotherapy-lesion-removal/), and [Electrosurgery](/treatments/surgical-dermatology/electrosurgery/).

Book an appointment promptly if an underarm growth bleeds repeatedly, develops a sore that does not settle, becomes painful, changes noticeably, or has an unusual colour or border. Seek urgent care for bleeding that will not stop with steady pressure, spreading redness with fever, or rapidly increasing swelling. A clinician can inspect the whole area and decide whether testing is needed.

Ask: Are these definitely skin tags? Could friction, shaving, or another skin condition be contributing? Which removal method fits each growth? What wound care should I use afterward, and which changes would mean I should return?
