Jaw filler is a cosmetic procedure designed to enhance the definition and contour of the lower face. The treatment involves injecting a gel-like substance, typically hyaluronic acid, deep into the tissue along the mandibular border. Swelling is an expected part of the body’s natural healing response following this injection. Understanding the predictable timeline of this temporary puffiness helps manage expectations for the final result.
The Standard Swelling and Bruising Timeline
Swelling begins immediately after the procedure, reacting to the needle trauma and the new material. This initial reaction, which includes fluid accumulation, generally peaks within the first 24 to 72 hours. During this period, the treated area may feel firm, tender, and appear noticeably larger or temporarily uneven compared to the desired final look.
As the inflammatory response subsides, the subacute phase of recovery starts, typically spanning from Day 4 through the end of the first week. Noticeable swelling diminishes rapidly, and the jawline will start to look less full. While the puffiness fades, you may still experience a subtle sensation of tightness or slight “lumpiness” as the filler settles into the surrounding tissue.
By the second week, the majority of the swelling and any minor bruising (ecchymosis) should be fully resolved. The treated area will begin to soften, and the results will look much closer to the intended outcome. Residual, very mild swelling can persist for up to four weeks as the filler integrates with the tissue. The true, final contour of the jawline is best assessed after this full month has passed.
Essential Post-Injection Care for Reducing Swelling
Proactive care in the first few days post-injection can significantly minimize the duration and severity of swelling. Applying a cold compress is highly effective, as the low temperature constricts blood vessels and reduces inflammatory fluid at the site. Gently apply a cold pack, wrapped in a thin cloth, for 10 to 15 minutes per hour during the first 48 hours.
Maintaining an elevated head position while sleeping is a powerful strategy to allow gravity to assist in draining excess fluid from the face. For the first two to three nights, sleeping with your head propped up on two pillows prevents fluid accumulation in the jaw area. Also, avoid strenuous exercise for at least 48 hours, as increased heart rate and blood pressure can exacerbate swelling and bruising.
The management of certain substances impacts recovery. It is recommended to avoid non-steroidal anti-inflammatory drugs (NSAIDs) like aspirin and ibuprofen both before and immediately after the procedure. These medications thin the blood and increase the likelihood of bruising and swelling. Conversely, avoiding high-sodium foods and alcohol following treatment prevents water retention, which can prolong the puffy appearance.
Recognizing Abnormal Swelling and When to Seek Help
While some swelling is normal, it must be distinguished from signs of a potential complication requiring medical attention. Normal swelling should always improve gradually after the initial peak on Day 2 or 3. If swelling worsens significantly after the fourth day, or is accompanied by severe, disproportionate pain, contact your provider immediately.
Signs of a possible infection, which may present days later, include late-onset extreme redness, persistent warmth, or a feverish feeling. Vascular complications, although rare, present as sudden, severe pain, accompanied by skin changes. These changes include blanching (turning white) or a mottled, gray-purple discoloration that spreads beyond the injection point. Any symptom suggesting a worsening or non-resolving condition warrants an immediate call to your injector.
