What should you know about Botox under the chin?

The muscles beneath and around the chin can influence lower-face movement and the appearance of a dimpled or tense chin. Botulinum toxin reduces signalling to carefully selected muscles. The visible change depends on whether muscle activity is the main contributor. Fullness may instead relate to fat, skin laxity, anatomy, or another condition. Temporary bruising, swelling, tenderness, asymmetry, altered smile, or weakness in nearby muscles can occur, especially in this mobile area.

Ask a qualified medical practitioner to examine the chin, jawline, lower lip movement, skin quality, and fullness before recommending injections. Mention dental or facial procedures, medicines, allergies, pregnancy or breastfeeding, and swallowing or speech problems. Agree on the target, expected change, follow-up, and alternatives. Avoid pressing or massaging the area unless directed. Learn more about [Botox](/treatments/injectables/botulinum-toxin-injection/) and [Botulinum Toxin Type A](/materials/botulinum-toxin-type-a/).

Contact the clinic for worsening swelling, increasing redness, drainage, severe pain, or a new uneven smile. Get urgent help if you develop difficulty swallowing, speaking, or breathing, widespread weakness, facial swelling, wheezing, or faintness.

Is muscle activity the main cause of my concern? Which nearby muscles could be affected? What alternatives address fat or loose skin? How will you check my smile and swallowing afterward?
