Double chin dissolving injections: what to know

The injected medicine is intended to disrupt fat cells in a planned area under the chin. It is not a general weight-loss treatment and cannot correct a recessed chin or significant loose skin. The clinician must map the treatment zone carefully because important nerves, blood vessels, and other structures lie in or near the neck. A consultation should cover previous procedures, medicines, allergies, pregnancy or breastfeeding, swallowing symptoms, and any lump that has not been diagnosed.

Choose a licensed medical professional who can assess the submental area and explain the product being used. Ask for written aftercare instructions. Swelling, tenderness, bruising, firmness, and temporary numbness can occur, so plan around work or social events and avoid pressing or massaging the area unless instructed. Results are assessed after the treated tissue and swelling have settled, and more than one appointment may be discussed. For a non-injectable alternative involving controlled cooling, read [Cryolipolysis](/treatments/laser-and-energy/cryolipolysis/). The broader treatment overview is [Fat Dissolving Injections](/treatments/injectables/fat-dissolving-injection/).

Contact the treating clinician promptly for worsening pain, spreading redness, increasing warmth, pus, marked asymmetry, difficulty swallowing, facial weakness, or trouble moving the mouth. Seek urgent help for breathing difficulty or rapidly increasing swelling of the face, mouth, or neck. A new untreated lump, persistent hoarseness, or unexplained neck swelling also deserves medical assessment rather than cosmetic treatment.

Ask what product will be used, why the area is suitable, and how the injection pattern protects nearby structures. Discuss expected swelling, warning symptoms, medication interactions, the follow-up schedule, and what happens if loose skin becomes more noticeable after fat reduction.
