What Is Looksmaxxing? What the Research Says Actually Works

Here is a fact most people get backwards. Show strangers two different photos of the same person, and their attractiveness ratings can differ more than the ratings of two entirely different people ^[1]. Not a little more. More.

That single finding reframes the whole idea of looksmaxxing. The forums obsess over the parts of a face you cannot change: jaw angles, eye tilt, skull proportions. The research keeps pointing at the parts you can.

This guide is about those parts. What attractiveness research really shows, which changes have serious evidence behind them, and which popular ideas fall apart the moment you look for a study.

What looksmaxxing actually means

Looksmaxxing is slang for deliberately working to look better. Online it splits into two camps.

The first is sometimes called softmaxxing: skin, hair, body fat, training, sleep, grooming, clothes. Things you do, repeatedly, that change how you look over weeks and months.

The second is hardmaxxing: surgery, injectables and other medical procedures. Those are decisions for a qualified clinician and outside what this library covers.

Between the two sits a third category that the forums rarely name: claims with no evidence at all. Bone reshaping from tongue posture. Jawlines from chewing gum. Scores built on the golden ratio. A lot of looksmaxxing content lives here.

So the useful question is not "what is looksmaxxing". It is "which of these things actually works, and how well do we know it". Every article in this library answers that with an explicit evidence grade, so you can see exactly how much weight a claim can bear.

What it means for you: treat looksmaxxing as a list of interventions to rank by evidence and impact, not as a belief system.

How to read the evidence in this library

Not all studies are equal, and looksmaxxing content almost never tells you which kind it is quoting. We do, on every claim, with one of four grades.

• Strong means a meta-analysis of randomized trials, a large randomized trial, a clinical guideline, or a very large and consistent body of observational work. Where a strong grade rests on observational data, we say so.
• Moderate means consistent observational meta-analyses, good single randomized trials, or lab findings that other labs have replicated.
• Emerging means small, early, uncontrolled or single-lab studies, or work in animals.
• Weak or contested means thin, conflicting or refuted evidence, or none at all.

Two more habits run through every article. We flag industry money where it exists, because a lot of the skin-perception research is run by cosmetics companies. And we write "a study found", never "science proves", because a single study is a data point, not a law.

The grades exist to make the copy bold where the evidence is strong and quiet where it is not. A sunscreen trial with 903 people over four and a half years deserves a confident sentence. A pilot study with 16 completers does not.

What it means for you: when you read any looksmaxxing claim, here or anywhere else, ask what kind of study it rests on before you change your routine around it.

Beauty is not only in the eye of the beholder

The comforting line is that attractiveness is purely personal. The data says otherwise.

A large review that ran eleven meta-analyses found that people agree strongly on who is attractive, within cultures, across cultures and across ethnicities ^[2]  Strong evidence. The same work found that attractive children and adults are judged and treated more positively.

Some of what drives that agreement is well mapped. Faces averaged together from many photographs are rated more attractive than the individual faces that went into them, and the more faces in the average, the higher the rating ^[3]  Strong evidence. Part of that effect may simply come from the smoother skin and better symmetry that averaging produces.

Symmetry, averageness and sex-typical features are all rated attractive across cultures ^[4]. But here is the part forum posts leave out: the link between those features and actual health is weak. In a study of 4,732 people, facial asymmetry was not associated with childhood illness ^[5], and another study found no facial trait that predicted immune function ^[6].

What it means for you: attractiveness is not arbitrary, which is exactly why it can be worked on. But a feature being attractive does not make it a verdict on your health or your worth.

Why looks carry real weight

If attractiveness only affected dating, it might be easy to wave away. It reaches further.

Economists found that plain-looking people earn around 5 to 10 percent less than average-looking people ^[7]  Strong evidence. In hiring experiments, a meta-analysis found attractive candidates were favored, with professionals as biased as students, although the bias has declined over time ^[8].

Those findings are correlational and lab-based, and they do not mean that improving your looks will raise your salary by any particular amount. They do mean the effect is real, measured, and not limited to one corner of life.

What it means for you: wanting to look your best is not shallow. It is a response to how people actually behave.

The biggest lever is presentation

Back to that opening finding, because it is the most useful one in the field.

In one set of experiments, the variation between different photos of the same person exceeded the variation between different people ^[1]. A second lab found the same pattern: different images of one face produce different impressions, with the spread within a person comparable to or larger than the spread between people ^[9]  Moderate evidence. Those impressions form within about 40 milliseconds.

This is a finding about photos and impressions, not about your skull. It does not mean anyone can become a perfect ten. It means lighting, angle, expression and grooming matter enormously, and you can control most of them.

The details are specific:

• Expression. The more intense a genuine smile, the more attractive a face is rated. Researchers found a smile could even compensate for relative unattractiveness ^[10]  Moderate evidence.
• Facial hair. There is no single best beard. Heavy stubble was rated most attractive while full beards rated highest for health and parenting ^[11], and preferences shift toward whatever is rare ^[12]  Moderate evidence.
• Glasses. In one study, rimless glasses raised perceived intelligence without lowering attractiveness, while full-rim frames lowered attractiveness ratings ^[13]  Emerging evidence.

What it means for you: before you worry about anything structural, control the inputs you can change today. Light, angle, expression and grooming are free.

The evidence-backed levers, ranked

Presentation changes how you look in a moment. These change how you look, period. Ranked roughly by strength of evidence and size of effect:

1. Sun protection

Daily sunscreen has the strongest long-term anti-aging trial behind it. In a 4.5-year randomized trial of 903 adults, people who used broad-spectrum sunscreen daily showed 24 percent less skin aging than those who used it at their own discretion ^[14]  Strong evidence. The trial measured prevention, not reversal. Read more in our skin article.

2. Not smoking

Identical twins share their genes, so twin studies control for genetics. In 186 twin pairs, the twin who smoked longer, or got more sun, looked older ^[15]. In another twin study, the smoking twin scored worse on under-eye bags, upper-lip lines and jowls, and even five extra years of smoking was enough to see ^[16]  Moderate evidence.

3. Body fat

A leaner-looking face is rated healthier and more attractive ^{[17, 18]}  Moderate evidence. Studies suggest roughly 8 kg of fat loss is where a man's face starts to look more attractive to others, and around 6 kg for women ^[19]. It is an inverted U: underweight faces are also rated less healthy. Details in body fat and facial definition.

4. Strength

In one study, how strong a man's upper body looked explained over 70 percent of how attractive his body was rated ^[20]  Moderate evidence. See strength training and appearance.

5. Sleep

In a BMJ experiment, strangers rated sleep-deprived people as looking less healthy and more tired ^[21]. Be careful with this one: the attractiveness change was tiny, and a later randomized trial from the same lab found no objective facial difference after one night of lost sleep ^[22]  Emerging evidence. Our sleep article sorts the real effects from the hype.

6. Diet and skin color

The healthy glow people notice is partly what you eat. In a six-week study of 35 people, an increase of about three portions of fruit and vegetables a day produced a perceptibly healthier skin color, consistent with carotenoids from food rather than a tan ^[23]  Moderate evidence. That study was small, mostly Caucasian and part-funded by Unilever. At matched color levels, raters preferred the carotenoid glow over a tan, an effect stronger on female faces ^[24]. Pills do not do it: beta-carotene supplements had no effect in the long sunscreen trial ^[14].

Even skin tone matters too. Studies that kept face shape identical and varied only color distribution found even-toned faces were judged younger ^{[25, 26]}  Moderate evidence. That research is linked to Procter and Gamble and mostly used female faces.

7. Hair

For male pattern hair loss, two drugs have strong trial evidence. Finasteride 1 mg slowed loss and regrew hair in large five-year trials ^[27]  Strong evidence. It is prescription only, and it carries real side effects: in trials, sexual side effects affected 3.8 percent of men on the drug against 2.1 percent on placebo, and European regulators confirmed suicidal ideation as a side effect in 2025 ^[28]. Topical minoxidil 5 percent produced 45 percent more regrowth than 2 percent in a 48-week trial ^[29]. Talk to a doctor before either. More in hair and hairline.

8. Teeth

In a study with 889 raters, photos edited to show a normal bite were rated most attractive, intelligent and agreeable ^[30]. Whitened teeth produced more favorable judgments of social competence and intellect ^[31]  Moderate evidence.

What it means for you: the levers with the best evidence are not secrets. The hard part is knowing which ones matter most for your face, and doing them in order.

Forum lore that does not hold up

This is where looksmaxxing content loses most people's time. Each of these is popular. None survives a look at the evidence.

The golden ratio. A systematic review found no association between golden-ratio proportions and attractiveness in any ethnicity ^[32], and the well-known phi face mask is methodologically flawed ^[33]  Strong evidence. That grade is strong evidence against. We do not score you on it.

Facial width-to-height ratio. The idea that fWHR reveals dominance or personality is mostly a perception effect. Behavioral links are small ^[34], and in a study of 137,163 people fWHR did not predict self-reported behavior ^[35]  Weak or contested.

Canthal tilt and "hunter eyes". The research base is one study of Photoshop-edited female faces ^[36]  Weak or contested. There is no male study and no replication. It is a forum concept, not a validated metric.

Mewing. No controlled study shows mewing changes an adult jaw, and the American Association of Orthodontists warns that forceful mewing risks tipped teeth and bite changes ^[37]  Weak or contested. Our mewing article explains what tongue and throat training is genuinely evidenced for.

Face yoga. The headline study had 16 completers, no control group, and a co-author who founded the program being tested ^[38]. A systematic review of nine facial-exercise studies found none were randomized or controlled ^[39]  Weak or contested.

Jawline gum. In a randomized trial of 58 young adults, chewing gum three times a day raised bite force but did not change jaw muscle size or jaw shape ^[40]  Moderate evidence.

Testosterone for a sharper jaw. In men, adult testosterone levels showed no relationship with how masculine their faces were. Facial structure was largely set by hormones before birth ^[41]  Moderate evidence.

Collagen pills. A meta-analysis of 23 trials looked positive overall, but the independently funded and higher-quality trials showed no benefit ^[42]  Weak or contested.

What it means for you: if a looksmaxxing claim comes with a dramatic before-and-after and no study, assume angle, lighting and weight explain it, because research says they can.

The mental side of looking better

Working on your appearance can go two ways. It can become a source of anxiety, or a source of momentum. The research gives a few reasons to expect the second, if you choose the right methods.

Resistance training reduced depressive symptoms across 33 randomized trials with 1,877 participants ^[43]  Strong evidence. That is a mood effect in trials, not a treatment for depression or a replacement for care. And a meta-analysis of 57 interventions found exercise improves body image, a small but real effect that can arrive before the mirror changes ^[44]  Moderate evidence.

The healthy stance is simple. A face analysis is a set of observations about how you present, not a rating of your worth. Use it to choose what to work on, then put it down and do the work.

What it means for you: pick evidence-backed habits that make you feel better as well as look better, and judge your progress by what you are doing, not by a single number.

Why most before-and-after photos prove nothing

If presentation can swing ratings this much, a lot of the internet's most persuasive evidence falls apart.

A dramatic before-and-after usually changes several things at once: the lighting, the camera angle, the distance from the lens, the head position, the expression, the hair and often the person's weight. Any one of those moves how a face is rated, and the research above shows the swing can be larger than the difference between two different people ^{[1, 9]}. That is why mewing before-and-afters are plausibly explained by age, weight loss, head posture, camera angle and lighting, and why the American Association of Orthodontists finds no evidence that mewing reshapes the jaw ^[37].

None of this means change is impossible. It means a photo pair is not a study. The changes worth your time are the ones that show up in trials with control groups, not in a carefully lit second picture.

What it means for you: when you track your own progress, keep the light, angle, distance and expression the same every time, or you will be measuring the camera instead of yourself.

Where to start

If you take one thing from this guide, take the order of operations.

First, presentation. It is immediate and free. Learn which light and angle suit your face, keep your expression relaxed or smiling, and settle on grooming that fits. This is the lever with the fastest return, and it costs nothing.

Second, skin. Daily sunscreen is the anti-aging habit with the strongest long-term trial behind it, and that trial measured years, not weeks. Add fruit and vegetables for color, and do not smoke.

Third, body composition and strength. Excess fat softens facial definition, and a strong upper body is one of the clearest signals in how a male body is rated. Training also improves mood along the way.

Fourth, sleep, hair and teeth. Sleep affects appetite, as a randomized trial showed. Hair loss has two drugs with strong evidence, both a conversation for a doctor. Teeth shape how attractive and intelligent people seem in rating studies.

Skip the golden ratio, the jawline gum and the mewing videos. The evidence already made that call.
