How to be prettier (naturally): the changes other people actually notice

Being prettier, in the research, is mostly not about features. People respond to rested eyes, even skin tone, contrast around the eyes and lips, framing and expression — and in controlled studies each of those changed how faces were rated without changing the face itself.

Most advice on how to be pretty comes as a list of twenty tips that mixes sunscreen with shopping, or as a forum thread about bone structure. This guide is neither. It goes through what observers actually react to when they look at a face, what each study measured, and how quickly each change shows. Nobody here is being told they need to be prettier. This is what the evidence says moves the needle if you want to.

How to be prettier without changing your face: what people respond to

Rhodes' 2006 review of facial attractiveness research is the standard summary: averageness, symmetry and sexual dimorphism all contribute, with modest effect sizes. Those are mostly fixed. But a face is also read through a surface layer that changes day to day and month to month — skin colour and evenness, signs of tiredness, the contrast of the features, the hair around it, and expression — and that layer has been measured to move ratings on its own.

If you want these as a day-by-day plan — a week, a month, 90 days — how to glow up lays them out that way. This guide is about why each one works.

Rested eyes: what sleep changes in how your face looks

Sleep is the change with the most direct evidence. Sundelin and colleagues photographed ten people after normal sleep and after a night of five hours followed by 31 hours awake, and had 40 observers rate specific features. Sleep-deprived faces were rated as having more hanging eyelids, redder and more swollen eyes, darker circles under the eyes, paler skin, more fine lines and more droopy mouth corners — and they looked sadder. Rash or tense lips did not change. Separate studies by the same group found the same faces rated less attractive after sleep loss, including after just two nights of restricted sleep.

That list is useful because it tells you exactly where the signals are: the eyes, the skin and the corners of the mouth. It is also why concealer, eye drops and a smile are the things people reach for after a bad night — they cover the same cues. The cheaper fix is the night itself.

Even skin tone: why skin does work people credit to features

When Matts and colleagues showed 353 people cropped patches of cheek skin from 170 girls and women, with no features at all, the more even the skin colour, the more attractive, healthy and youthful the skin was rated. Fink's earlier work found the same with whole faces. Much of what people describe as a pretty face is, when measured, an even-toned one.

Three things act on evenness with evidence behind them. Daily broad-spectrum sunscreen prevented measurable skin ageing over four and a half years in a randomised trial. Topical retinol improved fine wrinkles after 24 weeks in a randomised, vehicle-controlled trial in elderly adults. And eating more fruit and vegetables shifted skin colour measurably within six weeks. If you are under 18, sunscreen and moisturiser are enough; retinoids are for adults, should be avoided in pregnancy, and anything prescription-strength is for a dermatologist.

How to be prettier naturally: the fruit and vegetable finding

The diet study is the one most people have not heard of. Whitehead and colleagues measured skin colour in 35 people over six weeks while recording what they ate. Changes in fruit and vegetable intake tracked changes in skin redness and yellowness, matching the colour of carotenoid pigments; and the change from roughly three extra portions a day was enough to make skin look perceptibly healthier and more attractive. It was a small study, funded by Unilever, in Caucasian skin — but it is a natural change you can make, and the result is visible rather than theoretical.

Facial contrast: why brows, lashes and makeup work

This is the mechanism most beauty advice skips. Russell measured carefully controlled photographs and found female faces had greater luminance contrast between the eyes, lips and surrounding skin than male faces; turning the contrast up made an androgynous face look female, and turning it down made it look male. Makeup consistently increased that contrast. A follow-up by Jones, Russell and Ward in a larger set of faces found the pattern was specific: women had higher contrast around the eyes and lower contrast at the brows than men, and cosmetics exaggerated both.

Contrast also carries age. Porcheron and colleagues found that aspects of facial contrast decrease with age and that faces look younger when contrast is increased and older when it is decreased — first in Caucasian women, then across Chinese, Latin American and Black South African women rated by French and Chinese participants. The eyes, brows and lips fade slightly relative to skin over the years, and people read that as age.

Brows: the framing change you can make in one appointment

Brows are the easiest place to change contrast and framing without makeup. Groomed, filled-in brows add definition around the eyes; over-plucked ones remove it, and can take months to grow back. As for shape, there is no single ideal: when Feser and colleagues showed 357 people aged 12 to 85 the same female portraits with three brow variations, people under 30 preferred lower brows peaking toward the outer third and ruled out arched brows, while people over 50 preferred the opposite. Shape your brows to suit your face and your taste; any claim of one perfect brow is a trend.

How to be prettier without makeup

If contrast and evenness are what makeup works on, you can move both without it. Sleep lightens under-eye darkness and reduces redness in the eyes. Sunscreen and diet help skin evenness over time. Brushed, groomed brows and clean lashes define the eye area. Lip balm keeps lips smooth and their edge clear. Hair colour and the colours you wear near your face change how much your features stand out against your skin.

If you do wear makeup: it depends on your age

Makeup does work in studies. Etcoff and colleagues found faces with makeup, from natural to dramatic, were rated more attractive and more competent at a glance; the study was funded by a cosmetics company. But one finding matters especially for younger readers: Russell and colleagues showed that makeup made women in their 40s and 50s look younger, made women around 30 look no different — and made women around 20 look older. People associate makeup with adulthood. If you are young, less is not only allowed; it may read better.

Hair and colour: the frame around your face

A haircut that suits your face shape

Hair is the frame a face is seen in, and a cut adds visual width or length exactly where it falls. Width at the sides balances a longer face; length and a diagonal line balance a rounder one; softness at the forehead and jaw suits a face that is widest at the cheekbones. The face shape pages list cuts to try and avoid for each shape, with the reasoning. Knowing your shape before a haircut is the difference between a cut that suits you and a cut that suited the person in the photo.

Colours that suit your colouring

Colour seasons are a styling practice rather than a science with trials, and it is fairer to say so. But the idea connects directly to contrast: the colours closest to your face either work with the natural contrast between your hair, eyes and skin or fight it. Our colour analysis reads those three colours from a photo, corrects for the light using the whites of your eyes, and uses the contrast between hair and skin as part of placing you between bright and soft colouring.

Expression: how to look prettier in the next five seconds

Golle and colleagues asked people to choose the more attractive of two faces that varied in both attractiveness and how much they smiled. The strength of the smile strongly influenced the choice, and a happy expression could even compensate for a face being rated less attractive. The effect ran the other way too: more attractive faces were judged happier. It is the cheapest change on this page, and it works in person, in photos and on video. A genuine smile — one that reaches the eyes — also lifts the cheeks, which is why smiling photos flatter almost everyone.

What makes you look less pretty than you are

Many people searching how to be prettier have just seen a photo of themselves they hated. Before changing anything, it is worth knowing how many things make a face read worse without having anything to do with the face.

The mirror effect is real and measurable. Because every face is slightly asymmetrical, the face you see in the mirror is genuinely a different image from the one in a photo, and familiarity makes the mirror version feel right. In a study of 214 women, 73% preferred a mirror-reversed photo of themselves to the standard one. How to be photogenic goes through light and lens distance in detail.

Prettier-face advice you can skip

What exercise, rollers and chewing can and cannot reach is covered in facial asymmetry exercises. The short version for this guide: none of it changes the things observers were shown to respond to above.

Can you measure whether you got prettier?

Not with a geometry score, including the tools on this site. Am I Pretty and the attractiveness test measure the fixed layer — symmetry and proportions from facial landmarks. Nothing in this guide moves a landmark. Better sleep, more even skin, groomed brows, higher facial contrast and a smile will leave those scores exactly where they were, even when the difference is obvious in a photo. That does not mean the changes failed. It means the gains are in the layer geometry cannot see.

What those scores are useful for is a different worry: whether your proportions or symmetry are unusual. For almost everyone they are within the normal range, and a number can quieten a fear that a mirror feeds. If what you want to know is whether you look better, use photos taken in identical conditions — same window, distance, height and expression — a few weeks apart. How to know if you are attractive goes into what can and cannot be measured.

When wanting to be prettier stops being about looks

Wanting to look your best is ordinary. But if comparing, checking mirrors or retaking photos is taking up hours of your day, if you avoid being seen or photographed, or if nothing you change ever feels like enough, that is not something another routine will fix, and it is worth talking to a doctor, counsellor or someone you trust. For everything else: sleep, look after your skin, frame your face, and smile. The research is surprisingly consistent that those are the things people notice.
