Thread Lift Under the Chin: What to Know

The under-chin contour can reflect loose skin, fat, muscle movement, jaw shape or a combination of these. Threads placed beneath the chin aim to support selected tissue and may create a temporary contour change while healing develops. They do not directly remove fat, tighten every layer of the neck or change bone structure. The clinician should assess skin thickness, laxity, asymmetry, scars and nearby anatomy before recommending placement. [Sagging Skin](/symptoms/sagging-skin/) may be part of the concern, while [Sun-Damaged Skin](/conditions/photoaging/) can affect texture and elasticity.

Bring a clear description of the profile change you want and mention weight changes, medicines, allergies, previous injectables, surgery and dental treatment. Ask whether the concern is mainly skin or whether another treatment would address it more directly. After treatment, protect the area from pressure and follow instructions about washing, sleeping, facial movement, exercise and heat. Do not manipulate a tender or uneven area without advice. The clinician should identify the thread material, which may be [Polydioxanone Thread](/materials/polydioxanone-thread/), and explain alternatives such as [HIFU Skin Lifting](/treatments/laser-and-energy/hifu-treatment/) or a [Facelift](/treatments/surgical-dermatology/facelift/).

Seek prompt assessment for increasing pain, spreading redness, warmth, pus, fever, a thread showing through the skin, sudden contour change, skin colour change or trouble moving the lower face. Breathing difficulty or swelling in the mouth or throat requires emergency care. Bruising and tightness can occur early, but worsening rather than settling is a reason to call.

Ask: Is loose skin the main cause of my contour? Where would threads sit? What improvement is realistic? Could another treatment suit the fat or muscle component? How will you handle asymmetry or an exposed thread?
