Expected Timeline Days 1–3: Mild to moderate swelling and tenderness are common as the solution begins breaking down fat cell membranes. Some minor bruising may appear along the jawline but can be easily concealed. Days 4–10: Swelling dissipates significantly. The treated area may feel slightly firm to the touch as the body’s natural inflammatory response works to metabolize the released lipids. Weeks 2–4: The submandibular angle begins to sharpen. You will notice a visible reduction in the "pinchable" fat under the chin. Skin starts to retract and firm up. Month 1–3: As collagen synthesis is triggered by the injection's firming components, the jawline becomes more defined. To protect your results, adhere to a gentle routine: stay hydrated, use firming skincare, and avoid alcohol or high-sodium foods for the first week to minimize fluid retention.
