A smile lift is a cosmetic procedure that raises the corners of the mouth to correct a downturned or drooping appearance. It can be surgical (a corner lip lift) or non-surgical (using injectable neurotoxins or fillers), and both approaches target the same goal: making the mouth look more naturally upturned and pleasant at rest. Many people develop downturned mouth corners as they age, which can create an unintentionally sad or angry expression even when they feel fine.
How a Surgical Smile Lift Works
The surgical version, called a corner lip lift, involves removing a small triangle of skin at each corner of the mouth. The surgeon marks the current corner of the mouth, then identifies where the patient wants the new corner to sit. A third point is placed along the border where the lip meets the skin, roughly 13 millimeters from the mouth corner. The triangle formed by these three points is excised just below the skin’s surface, and the remaining tissue is sutured upward into the new position.
The incision is placed along the vermilion border, the natural line where the colored part of your lip meets the surrounding skin. This placement keeps the resulting scar well-hidden. Most patients find the scar acceptable once it fully matures, since it sits in a crease the eye already expects to see.
Corner Lift vs. Subnasal Lip Lift
People searching for smile lifts often encounter another procedure called a subnasal or bullhorn lip lift, and the two solve different problems. A subnasal lift shortens the space between the nose and upper lip, creating a fuller central lip and restoring visible tooth show that fades with age. It does not, however, address downturned corners. A corner lip lift does the opposite: it raises the outer edges of the mouth but doesn’t add much fullness to the central lip.
For someone whose main concern is looking stern or unhappy at rest, the corner lift is the more targeted fix. For someone who wants a fuller upper lip and shorter philtrum (the groove between nose and lip), the subnasal lift is more appropriate. Some patients combine both, or pair a corner lift with filler along the central lip, to address multiple changes at once.
The Non-Surgical Option
If surgery feels like too big a step, a non-surgical smile lift uses a neurotoxin (the same type used for forehead wrinkles) injected into the depressor anguli oris, a muscle that pulls the corners of the mouth downward. By relaxing that muscle, the corners naturally drift upward. The dose is small, and results typically appear within a week or two.
The tradeoff is longevity. Non-surgical results last roughly three to four months before the muscle regains full function and the corners settle back. Surgical results, by contrast, are permanent in the sense that the tissue has been physically repositioned. Natural aging continues, but the structural change from surgery can last five to ten years or more before the effects of gravity become noticeable again. Injectable approaches require repeat treatments to maintain the look.
Who Is a Good Candidate
The best candidates for a surgical smile lift have visibly downturned mouth corners that bother them at rest. Age matters less than anatomy. Some people in their 30s have naturally downturned corners, while others don’t develop them until their 50s or 60s. The key question is whether the drooping is significant enough to justify a permanent procedure, or whether a non-surgical approach would accomplish what you’re after.
People with a history of keloid or hypertrophic scarring should discuss this with their surgeon, since the procedure does leave a scar at each corner of the mouth. Modified techniques exist for scar-prone patients that minimize tension on the wound, but the risk is worth weighing carefully.
Recovery Timeline
Recovery from a surgical smile lift is relatively quick compared to larger facial procedures. Stitches come out within a few days, or dissolve on their own depending on the suture type. Swelling and bruising begin to fade within the first week and are typically gone within a month.
The surgical site itself heals in about six to eight weeks. Your lips may feel tight or stiff for a couple of months after the procedure, and in some cases it can take up to six months before sensation and movement feel completely normal again. Most people return to work and daily activities within a week, though you’ll want to avoid anything that stretches or strains the mouth (think wide yawning or aggressive chewing) during early healing.
What It Costs
A lip lift averages around $3,126 nationally, with prices ranging from about $2,400 to over $6,100 depending on the specific technique, the surgeon’s experience, and where you live. Geographic variation is significant. In California, the average runs closer to $3,900, while in states like Arkansas it drops to around $2,700. A corner lift specifically tends to fall within this broader range, though pricing varies by practice.
Non-surgical options cost considerably less per session, typically a few hundred dollars for the neurotoxin injection. But because results fade every few months, the cumulative cost over several years can approach or exceed the one-time surgical price. Insurance does not cover either approach, since both are considered cosmetic.
Risks to Know About
The most common concerns with a surgical smile lift are scarring, asymmetry, and an overdone appearance. If too much tissue is removed, the corners of the mouth can look unnaturally elevated, sometimes described as a “joker” effect. This is why conservative excision is standard: it’s easier to take a bit more tissue later than to reverse an aggressive first surgery.
Asymmetry is possible if healing differs between the two sides, though minor unevenness often resolves as swelling subsides. Infection and poor wound healing are risks with any surgical procedure but are uncommon in this area when proper aftercare is followed. Temporary numbness or tightness around the mouth is normal and resolves over weeks to months.
