How health shapes your face

What the research actually says about the things people do to look better — the ones that work, the ones that half-work, and the ones that are forum lore. Every article is graded by how strong the evidence really is.

00Four grades, stated every time

Each article is graded by the claim its title asks about. The claims inside it carry their own grades, so you always know how much weight a sentence can bear.

Strong evidence
A meta-analysis of randomized trials, a large randomized trial, a clinical guideline, or a very large and consistent body of observational research. We state these plainly.
Moderate evidence
Consistent observational reviews, good single randomized trials, or lab findings that other teams have replicated. Real, and worth acting on, with limits we name.
Emerging evidence
Small, early, uncontrolled, single-lab or animal studies. Interesting and plausible, not settled. We say so every time.
Weak or contested
Thin, conflicting or refuted evidence, or none at all. When a popular claim lands here, we tell you, and we tell you what to do instead.

What Is Looksmaxxing?

Most of what moves how attractive you look is not your bone structure, and the research on that is clearer than the forums suggest.

Face structure

Airways, tongue posture and face fat: what can change the shape of a face, when, and what cannot.

Does Mouth Breathing Change Your Face?

The link between breathing and face shape is one of the most repeated ideas in looksmaxxing, and the honest version is narrower, and more useful, than the one you have heard.

Does Mewing Work?

Mewing promises a new jawline from a resting tongue, and the evidence for that is close to nothing, but the idea sits right next to one that genuinely works.

Body Fat and Your Face

Your jawline may already be there. The research says how much fat loss it takes before other people notice, and it is less than you might think.

Skin & hair

The best-evidenced anti-aging habit there is, the skincare that has trials behind it, and what actually works for hair loss.

Skin Health and Your Face

One habit has a 4.5-year randomized trial behind it. Most of the rest of the skincare aisle does not.

Hair Loss and Your Hairline

Two treatments have large trials behind them, one of them comes with side effects you need to hear about first, and the rest of the list is thinner than its marketing.

Body & habits

Sleep, training and posture — the habits that change how a face and a body read to other people.

Is Beauty Sleep Real?

Sleep changes how your face reads to strangers, though less dramatically than the internet claims, and its biggest effect on your looks may run through your appetite.

Strength Training and Your Looks

How strong you look drives how your body is rated more than almost anything else measured, and the benefits of lifting run well past the mirror.

Forward Head Posture and Attractiveness

Posture is one of the few things about how you look that trials show you can measurably change, and an open posture changes how people respond to you.
