Skin tag (acrochordon): benign common skin growths

Appearance and location

Skin tags are usually pedunculated (attached by a slender stem), smooth or slightly wrinkled, and may hang freely. Frequently affected sites include:

• neck and under the chin
• armpits and groin
• under breasts and skin folds
• eyelids and areas where clothing or jewelry rubs

They can appear singly or in clusters and may be more noticeable when they catch on clothing or jewelry.

Causes and when they appear

The exact cause is not fully understood, but skin tags are associated with friction, skin rubbing, and creasing. They are more common with increasing age and in people with obesity, diabetes, or certain hormonal changes such as pregnancy. Genetics can also play a role. Although benign, new or changing lesions should be evaluated to exclude other skin conditions.

Diagnosis and differences

Diagnosis is usually clinical — a health professional can identify a skin tag by inspection. Other growths that can look similar include moles, warts, and benign keratoses; rarely a biopsy is recommended when the appearance is atypical or there is rapid change, bleeding, or pain.

Management and removal

Most skin tags do not require treatment unless they cause discomfort or cosmetic concern. Common removal methods performed by clinicians include:

• snip excision with sterile scissors or scalpel
• cryotherapy (freezing)
• electrocautery or cauterization

These procedures carry small risks of bleeding, infection, or scarring and are best done by a trained practitioner. Home remedies and unverified techniques can lead to complications; consult a clinician or follow reliable guidance before attempting removal (seek medical advice).

In summary, skin tags are common, non‑cancerous skin growths. They tend to increase with age and friction, are easily diagnosed, and can be removed safely if necessary. If a lesion changes in appearance, bleeds, or is painful, professional assessment is recommended.
