The Mona Lisa Smile: How a Non-Surgical Lip Lift Can Transform Your Expression Without Surgery

There’s a reason Leonardo da Vinci’s Mona Lisa has captivated viewers for over five centuries. That enigmatic, subtly upturned smile radiates warmth, mystery, and approachable beauty—qualities that feel effortlessly natural rather than forced. At Beverly Hills Aesthetics, Dr. Sam Assassa has perfected a non-surgical technique that recreates this effect, helping Los Angeles patients achieve a more youthful, pleasant resting expression without surgery, incisions, or significant downtime.

If you’ve noticed your mouth corners turning downward over time, creating an unintentionally stern or tired appearance even when you feel perfectly content, the Non-Surgical Smile Lift might be the solution you’ve been seeking.

Why Our Smiles Change Over Time

The corners of our mouths don’t stay static throughout our lives. Multiple factors contribute to the gradual downturning that many patients notice as they age.

Collagen and elastin—the proteins responsible for skin’s firmness and bounce—decrease steadily after our mid-twenties. This loss affects the entire face, but the mouth area shows it prominently because the muscles around our lips work constantly throughout every day, speaking, eating, and expressing emotions.

Volume loss compounds the problem. As fat pads in the midface diminish, skin that once had underlying support begins to droop. This gravitational effect pulls the corners of the mouth downward, creating marionette lines that extend from the lip corners toward the chin.

Additionally, the muscles responsible for pulling the mouth corners down—the depressor anguli oris muscles—can become overactive relative to the muscles that lift them. This muscular imbalance contributes to the perpetually unhappy expression that frustrates so many patients who visit our Beverly Hills office.

The result? Looking in the mirror and seeing someone who appears sad, angry, or disapproving—even when you feel none of those emotions.

The Art Behind the Non-Surgical Smile Lift

Dr. Sam Assassa’s approach to the Non-Surgical Smile Lift exemplifies the artistic philosophy that has defined Beverly Hills Aesthetics since 1995. Rather than dramatic transformation, the goal is subtle refinement that looks completely natural—enhancement that others notice as “you look great” rather than “you had something done.”

The procedure strategically combines neuromodulators (such as Botox, Dysport, or Xeomin) with precisely placed dermal fillers to address both muscular and volumetric components of downturned mouth corners.

• Neuromodulator Placement: Small amounts of neuromodulator are injected into the depressor anguli oris muscles at each corner of the mouth. By relaxing these muscles, the lip corners are freed to return to a more neutral or slightly elevated position. The effect is subtle—you maintain full control of your expression while eliminating the downward pull that creates a frowning appearance.
• Strategic Filler Support: Dermal fillers restore lost volume and provide structural support at the mouth corners. When placed by an experienced injector like Dr. Assassa, fillers lift and stabilize the commissures (lip corners) while softening any marionette lines that have developed.

The combination creates synergy—neuromodulators release the downward tension while fillers provide upward support. Together, they achieve results neither treatment could accomplish alone.

What Makes Dr. Assassa’s Technique Different

Not all smile lift procedures deliver the same results. The difference lies in understanding facial anatomy at a level that goes beyond textbook knowledge—and in having the artistic eye to know exactly how much enhancement creates beautiful results versus overdone outcomes.

Dr. Assassa brings over three decades of non-surgical aesthetic experience to every procedure. As president of the American Association of Aesthetic Medicine and Surgery since 2006, he has trained thousands of physicians worldwide in advanced injection techniques. His Beverly Hills practice has performed more non-surgical facial procedures than perhaps any other in the area.

This experience translates directly to patient results. Dr. Assassa understands that:

• Dosing matters profoundly. Too much neuromodulator near the mouth can affect speech or create an asymmetrical smile. Precise, conservative dosing ensures natural movement while still achieving the desired lift.
• Placement requires millimeter accuracy. The difference between a beautiful result and a compromised one can come down to injection placement measured in millimeters. Dr. Assassa’s extensive experience means he knows exactly where products belong for optimal, safe outcomes.
• Individual anatomy varies significantly. What works perfectly for one patient may be entirely wrong for another. Each treatment plan is customized based on facial structure, existing muscle patterns, and aesthetic goals.

The Treatment Experience

Patients often feel surprised by how quick and comfortable the Non-Surgical Smile Lift actually is. The entire procedure typically takes 15 to 30 minutes, making it genuinely possible to complete during a lunch break.

Before treatment begins, Dr. Assassa evaluates your facial structure at rest and while you make various expressions. This assessment identifies exactly which muscles are contributing to the downturned appearance and how your face moves naturally—critical information for planning precise injection sites.

The injections themselves involve minimal discomfort. Most patients describe the sensation as a tiny pinch that lasts only a moment. For those who prefer additional comfort measures, topical numbing cream can be applied before treatment.

There’s no significant downtime following the procedure. Some patients experience mild swelling or occasional bruising at injection sites, but these effects typically resolve within a few days and can be covered with makeup if desired. Most patients return to normal activities immediately, though we recommend avoiding strenuous exercise for 24 hours.

When Results Appear—And How Long They Last

The timeline for results depends on which components were used in your treatment.

Neuromodulator effects begin appearing within a few days, with full results visible around two weeks after treatment. The muscle relaxation typically lasts three to four months, at which point maintenance treatment can extend your results.

Filler results are visible immediately, though minor swelling may initially make the area appear slightly fuller than the final outcome. Once swelling resolves over a few days, you’ll see the true result—natural lift and support at the mouth corners. Depending on which filler is used, results can last six months to over a year.

Many patients find that regular maintenance treatments actually improve their results over time. Consistent neuromodulator use can retrain overactive muscles to remain more relaxed, while repeated filler treatments stimulate some natural collagen production in the treated areas.

Combining the Smile Lift with Comprehensive Facial Rejuvenation

While the Non-Surgical Smile Lift delivers beautiful standalone results, many Beverly Hills Aesthetics patients choose to address multiple areas during the same visit for comprehensive rejuvenation.

The mouth exists in relationship to the entire face. Patients concerned about downturned lip corners often also notice hollowing under the eyes, flattening cheeks, or deepening nasolabial folds. Dr. Assassa’s expertise in the non-surgical facelift—including his signature CosmoFaceLift™ procedure—allows him to create harmonious improvement across all areas of concern.

During your consultation, Dr. Assassa can discuss whether combining treatments makes sense for your goals. Some patients prefer addressing one area at a time, while others appreciate the efficiency and synergistic results of comprehensive treatment in a single session.

Ideal Candidates for the Non-Surgical Smile Lift

The Non-Surgical Smile Lift works beautifully for patients who:

• Notice downturned mouth corners that create a perpetually unhappy or stern appearance
• Feel their resting expression doesn’t match how they actually feel inside
• Want natural-looking enhancement rather than dramatic change
• Prefer avoiding surgery with its associated downtime, risks, and recovery
• Seek maintenance-friendly results that can be adjusted and refined over time

The procedure suits patients across a wide age range. Some patients in their 30s seek preventive treatment as they first notice the early signs of downturning. Others in their 50s, 60s, and beyond achieve beautiful rejuvenation that takes years off their appearance.

During your consultation, Dr. Assassa will assess whether the Non-Surgical Smile Lift is appropriate for your specific anatomy and goals, or whether alternative or additional treatments might better serve your needs.
