Besides Kybella (deoxycholic acid), other non-surgical injectable options for reducing a double chin include other fat-dissolving injections formulated with similar acids, lipolytic injections using phosphatidylcholine/soybean lecithin blends, and some clinics offer combination protocols that mix fat-dissolvers with collagen stimulators or muscle-relaxing agents to improve contour. In general, deoxycholic acid–based treatments tend to be more studied and effective at breaking down submental fat, though comfort levels vary; some formulas may cause less discomfort or swelling, but results might be more subtle. Most options require multiple sessions (usually 2–4 spaced weeks apart) before seeing noticeable reduction, and side effects can include swelling, tenderness, numbness, and bruising that typically resolve in days to weeks. When choosing the best option, consider your goals, amount of chin fat, pain tolerance, downtime needs, and provider experience—a qualified clinician can assess your anatomy and recommend whether injections alone or a combination with skin-tightening procedures might give the best balanced result.
