You can make your face look longer and thinner through a combination of styling techniques, lifestyle changes, and, if you want more dramatic results, cosmetic procedures. Some approaches create an instant visual illusion, while others produce physical changes over weeks or months. The right mix depends on how much change you’re after and whether you want something reversible or permanent.
Why Some Faces Look Rounder Than Others
Your facial shape is largely determined by bone structure, muscle size, fat distribution, and water retention. Genetics play a strong role in face height, facial width, and nose shape. In a study of nearly 5,000 teenagers, face height alone accounted for about 29% of the total variation in facial appearance, making it the single biggest factor in how different faces look from one another.
That said, not everything is fixed at birth. Jaw muscle bulk, cheek fat volume, and soft tissue fullness are all modifiable. The width of your lower face, for instance, is heavily influenced by the size of your masseter muscles (the muscles you clench when you chew). And facial fat pads in the cheeks and temples can shrink or grow depending on your body weight. So while you can’t reshape your skull, you have more control over the soft tissue that sits on top of it than you might expect.
Hairstyles That Elongate Your Face
The fastest way to make your face appear longer and thinner is to change how it’s framed. Certain haircuts draw the eye vertically and minimize width, creating the illusion of a narrower shape without touching your face at all.
Long layers are the go-to recommendation. The length pulls the eye downward while layers add movement that prevents the hair from sitting flat and wide around your cheeks. Ask a stylist for defined layers starting around chin length that gradually cascade through the rest of your hair. If you prefer straight hair, wearing it long and sleek has a similar elongating effect.
Adding height at the crown makes a noticeable difference. A bit of volume on top shifts the visual center of your face upward, creating the impression of a longer, more oval shape. You can achieve this with volumizing products, a round brush while blow-drying, or simply teasing the roots slightly at the crown.
A few other tricks that work well together: shift your part to one side (asymmetry breaks up roundness and adds visual length), try long side-swept bangs rather than blunt straight-across bangs, and consider face-framing layers paired with beach waves. Avoid chin-length bobs that hit at the widest point of your face, as these emphasize width rather than length.
Contouring and Highlighting Placement
Makeup contouring uses shadow and light to reshape how your face reads in three dimensions. The core principle for elongation: darken the sides, brighten the center.
For a rounder face, apply contour shade along the sides of your forehead and temples to visually narrow the upper face. Then sweep contour below your cheekbones, starting at your ears and angling down toward your jawline rather than straight across. This diagonal line adds the appearance of length. Blend well so there are no harsh edges.
Highlighter goes in the center of your forehead and the center of your chin to draw light (and attention) to the vertical axis of your face. Under the eyes, apply highlighter in an inverted triangle shape. This combination of darkened sides and a bright center stripe effectively stretches how your face appears, sometimes dramatically so, depending on how much product you use and how your lighting hits.
Reducing Facial Puffiness
Sometimes a round, full face isn’t about bone or fat. It’s water. Facial puffiness from fluid retention can add noticeable width, especially around the cheeks, under the eyes, and along the jawline. Cutting down on sodium is the simplest fix. High salt intake makes your body hold onto extra water, and that fluid often shows up in the face first, particularly in the morning.
Alcohol has a similar effect, as does sleeping flat without any head elevation. Staying consistently hydrated (counterintuitive as it sounds) helps your body release retained water rather than hoard it. Some people notice visible changes in facial fullness within days of lowering their sodium intake, though the effect varies depending on how salt-sensitive you are.
How Weight Loss Affects Facial Shape
If you’re carrying extra body fat, losing weight will thin your face. The cheeks and temples are among the most responsive areas. In one volumetric analysis of patients on a weight loss medication, an average 21% reduction in body weight over about nine months produced a 70% reduction in cheek fat pad volume and a 42% reduction in temple fat.
Those are significant numbers, but there’s a tradeoff. After substantial weight loss (typically a BMI drop of 10 or more points), the skin and soft tissue may not fully retract. A study of post-bariatric surgery patients found 88% volume loss in the midface, but also excess skin in the jowl and under-chin area. Patients who lost large amounts of weight appeared an average of five years older than their actual age, compared to just one year older for those with more moderate weight loss. Gradual, moderate fat loss tends to thin the face without creating that hollowed or sagging look.
Masseter Reduction for a Slimmer Jawline
If your lower face looks wide or square, the masseter muscles may be the reason. These are the thick muscles on either side of your jaw that power chewing and clenching. In people who grind their teeth or have naturally bulky masseters, these muscles can make the lower face look significantly wider than it needs to be.
Injecting a neurotoxin (commonly known by brand names like Botox or Dysport) into the masseter causes the muscle to gradually shrink from reduced use. A prospective study using 3D facial imaging found that lower face volume decreased significantly by four weeks after injection, with the most prominent reduction at 12 weeks. The effect is visible as a slimmer, more tapered jawline.
Results typically last four to six months before the muscle slowly regains its bulk, so maintenance injections are needed. With repeated treatments over a year or more, some patients find the muscle stays smaller for longer between sessions. This is one of the most popular non-surgical options for facial slimming and requires no downtime.
Chin Fillers for Vertical Length
Dermal fillers injected at the chin can physically add length to your face. A longer, more projected chin shifts your facial proportions so that the overall shape reads as more oval and less round. Filler is typically placed at two to three sites in the front of the chin, with very small amounts (as little as 0.05 to 0.1 ml per injection point) to avoid overcorrection.
The key is projection, not width. A skilled injector will build the chin forward and slightly downward rather than outward, which would widen it. Filler along the jawline itself can also sharpen the border between your face and neck, creating a more defined angle that reads as thinner. The results are immediate, last roughly 12 to 18 months depending on the product used, and are reversible if you don’t like the outcome.
One important note: filling the area over the masseter muscle broadens the jaw and is used when people want a more angular, wider look. If your goal is a thinner face, make sure your provider understands you want chin projection and jawline definition without added lateral width.
Buccal Fat Removal
Buccal fat pads are the walnut-sized fat deposits deep in your cheeks that give the lower face its fullness. Removing them is a surgical procedure that permanently thins the cheek area, creating more hollow, sculpted contours. Good candidates are at a stable weight, in overall good health, and specifically bothered by fullness in the cheek hollows rather than general facial roundness.
This procedure has become popular in recent years, but it’s worth approaching carefully. Unlike fillers or neurotoxin, buccal fat removal is not reversible. Faces naturally lose volume with age, and removing buccal fat in your twenties or thirties can lead to a gaunt appearance later in life. The best candidates tend to have genuinely full cheeks that remain round even at a healthy body weight.
Surgical Jaw Repositioning
For people whose facial proportions are determined by skeletal structure rather than soft tissue, orthognathic surgery can physically change the vertical height of the face. The most relevant procedure involves repositioning the upper jaw (maxilla) upward by 3 to 7 mm, which shortens the lower third of the face. This surgery addresses a condition called vertical maxillary excess, where the midface is disproportionately long, often causing a “gummy smile” or difficulty closing the lips at rest.
This is a major procedure typically done in combination with orthodontic treatment. Recovery involves follow-up appointments at one, three, six, and twelve months. Facial changes tend to stabilize between six and twelve months after surgery. Nerve sensation in the area may take three to six months to return to normal. This option is generally reserved for cases where the jaw structure causes functional problems (like an open bite) alongside the cosmetic concern.
Do Facial Exercises and Mewing Work?
Mewing, the practice of pressing your tongue firmly against the roof of your mouth to reshape your jaw, has exploded on social media with dramatic before-and-after claims. The scientific evidence does not support those claims. A systematic review found no robust clinical data showing that mewing produces significant changes in bone structure or facial shape. Its popularity appears driven by anecdotal evidence and accessibility rather than proven results.
Facial exercises more broadly have shown some limited, region-specific improvements. Across five studies involving 144 patients, exercises produced measurable changes in cheek skin appearance, jawline surface distances, and muscle bulk in certain areas. But the improvements were modest, and reviewers concluded the current evidence is insufficient to recommend these techniques with confidence. They’re safe and free, so there’s little downside to trying them, but expecting the kind of transformation you’d get from the other methods on this list is unrealistic.
