Why Is One Side of My Lip Bigger Than the Other After Fillers?

Lip fillers are a popular cosmetic procedure for enhancing lip volume and shape. While many seek a fuller appearance, unevenness or asymmetry is a common concern. This initial imbalance is often temporary and manageable. Understanding contributing factors helps manage expectations and provides reassurance.

Common Reasons for Unevenness

Several factors can contribute to unevenness after lip filler injections. Immediately following the procedure, swelling and bruising are normal reactions that can temporarily distort lip symmetry. Swelling may not occur symmetrically, making one side appear fuller than the other in the initial days.

Natural facial asymmetry also contributes; lips are rarely perfectly symmetrical, and fillers might highlight pre-existing differences. Injector technique, including precise application, amount, and depth, influences the final outcome. Uneven filler distribution or differences in tissue density within the lips can also lead to an asymmetrical appearance.

Less commonly, filler migration can cause unevenness if the product spreads unintentionally from its original placement, creating lumps or an asymmetrical look. This can happen if too much filler is injected or due to improper injection technique.

Initial Actions and Healing Timeline

Patience is key during the healing process following lip filler injections. Initial asymmetry is often due to post-procedure swelling, which typically peaks within the first 24 to 48 hours and subsides over time as the body adjusts.

Applying a cold compress or ice pack wrapped in a cloth can help reduce swelling and discomfort during the first 24 to 48 hours. Apply cold compresses in increments, 10 to 15 minutes at a time, without direct pressure. Gentle massage should only be done if specifically instructed by your provider to avoid complications like filler displacement. Most visible swelling resolves within 5 to 7 days, with complete healing and final results visible in about two weeks.

When to Contact Your Practitioner

While some unevenness and swelling is expected initially, certain signs warrant contacting your practitioner. If asymmetry persists or worsens after the initial healing period (generally two weeks), seek a re-evaluation. This timeframe allows most swelling to resolve, revealing the true settled state of the filler.

Beyond persistent unevenness, it is important to be aware of potential signs of complications. These include severe pain that builds after the treatment, especially if it’s not relieved by over-the-counter pain medication. Other concerning symptoms are unusual discoloration of the skin, such as purple or dark gray tones, or blanching (whitening) of the skin, which could indicate compromised blood flow. Extreme swelling, increasing redness that spreads, or any signs of infection like pus or warmth, also require immediate medical attention.

Professional Corrective Measures

If unevenness or other issues persist after the healing period, aesthetic practitioners have several professional corrective measures available. One approach involves manual manipulation or massage performed by the practitioner. This technique can help redistribute the filler within the lips, especially if the unevenness is noted immediately after injection or due to minor clumping. The practitioner may use specific motions to integrate the filler and smooth out irregularities.

In some instances, a small amount of additional filler might be strategically placed in the less full area to balance the lips. This touch-up method helps to achieve a more symmetrical appearance once the initial swelling has subsided.

For more significant unevenness or if filler has migrated, an enzyme called hyaluronidase can be used. This enzyme specifically breaks down hyaluronic acid fillers, allowing for the dissolution of excess or misplaced product. Dissolving the filler provides an opportunity for re-treatment or for the lips to return to their pre-filler state.

Choosing an Experienced Practitioner

Selecting a qualified and experienced professional is an important step in minimizing the risks of unevenness and other complications with lip fillers. It is beneficial to seek practitioners who are board-certified dermatologists, plastic surgeons, or highly trained aesthetic nurses. These professionals typically possess a thorough understanding of facial anatomy and injection techniques. Their skill and precision during the injection process can significantly influence the symmetry and natural appearance of the results.

Before committing to a procedure, it is helpful to review the practitioner’s portfolio, including before-and-after photos of their previous patients. Patient testimonials can also provide insight into their experience and outcomes. A comprehensive consultation is also a beneficial step. During this meeting, you can openly discuss your aesthetic goals, concerns, and any questions you may have, allowing the practitioner to assess your facial anatomy and create a customized treatment plan.
