For 1 week before: avoid blood-thinning supplements (vitamin E, fish oil, gingko, garlic supplements) and over-the-counter NSAIDs (Advil, Motrin, aspirin) unless medically necessary — these increase bruising risk. Avoid alcohol for 24 hours prior. Arrive with clean, makeup-free skin if possible. Eat beforehand to avoid lightheadedness. Plan to avoid laying flat for 4 hours after Botox.
Kybella (also known as deoxycholic acid, fat dissolving injection) is one of several options in this treatment category. The main differences vs. alternatives are formulation, onset time, duration, and pricing. Your St. Louis provider can recommend the best fit for your specific goals during consultation.
Kybella is synthetic deoxycholic acid — a molecule your body naturally produces to break down dietary fat. When injected into the fat under your chin, it dissolves the fat cell membranes. Your body then clears the destroyed cells via the lymphatic system over the following weeks. Since the cells are gone for good, results are permanent.
Most people need 2–4 treatment sessions spaced 4–6 weeks apart. Some need up to 6 sessions for severe fullness. Your provider will assess your "before" and recommend a treatment plan during consultation.
Significant. Plan for 3–7 days of visible "bullfrog" swelling under the chin after each session, which is the body's response to the destroyed fat cells. Bruising and tenderness are also common. Most people schedule sessions when they can lay low for a week.
There's burning and stinging during the injections that lasts a few minutes — many providers use ice or numbing cream. The 12–24 hours after treatment can be tender and uncomfortable, eased with cold packs and OTC pain relievers.
Not significantly. Kybella destroys fat; it doesn't tighten skin. If you have loose or sagging skin under your chin, you may want to combine Kybella with a skin tightening treatment (Morpheus8, Sofwave, or Ultherapy) or consider chin liposuction if skin laxity is significant.
CoolSculpting also has an FDA-approved chin applicator. Both work; both require multiple sessions; both produce permanent fat reduction. Kybella is injection-based (no device pulling on skin), while CoolSculpting uses cold and suction. Kybella often has more visible post-treatment swelling. Cost is similar. Your provider's experience with each may inform the recommendation.
