Double Chin Injection Lipolysis

Renomé Clinic treats submental fullness — the 'double chin' — with injection lipolysis: a fat-dissolving solution (deoxycholic acid–based) injected in a measured grid into the fat pad beneath the chin. The compound disrupts fat-cell membranes; the released fat is then cleared gradually through the lymphatic system over the following weeks, and the destroyed fat cells do not return. Each session takes about 20–30 minutes; expect notable swelling of the area for several days. Two to four sessions typically produce a visibly tighter chin-neck angle in patients with good skin tone.

A double chin is one of the most stubborn aesthetic complaints — submental fat often persists regardless of weight, driven by anatomy and genetics. Injection lipolysis offers a non-surgical, permanent reduction of this discrete fat pad. **How it works:** The active compound, deoxycholic acid, is a synthetic version of a bile acid the body itself uses to emulsify dietary fat. Injected into subcutaneous fat, it disrupts adipocyte cell membranes (cytolysis). Over the following 4–6 weeks, macrophages clear the released lipids and cell debris via the lymphatic system, and fibroblast activity in the treated zone produces a mild secondary skin-tightening effect. Because mature fat cells do not regenerate in meaningful numbers, the reduction is permanent at stable body weight. **The session at Renomé Clinic:** The physician marks the submental fat pad with a grid template, confirms the injection plane is safely within the fat (away from the marginal mandibular nerve), and places a series of small injections — about 20–30 minutes in total, with numbing cream or cooling beforehand. **What to expect after:** This treatment's honest trade-off is the swelling: the chin area swells noticeably for 3–7 days (occasionally longer) — a sign the compound is working, but worth planning around socially. Numbness or firmness of the area can persist for a few weeks and resolves spontaneously. Bruising is common and concealable. **Course:** 2–4 sessions at 4–6 week intervals, scaled to the fat volume. First visible change typically appears after the second session as cleared fat and resolved swelling reveal the new contour. **Candidate selection:** Best for discrete submental fat with reasonably elastic skin. When the issue is loose skin or platysmal banding rather than fat, lipolysis will disappoint — the clinic's combined surgical-dermatology team can instead offer chin/neck liposuction, thread necklift, or a surgical neck lift (from 52,000 Kč), and the consultation sorts candidates honestly between these options.
