Three-dimensional soft-tissue facial anthropometry and dermatologist-rated attractiveness among Thai women: implications for facial aesthetic and orthognathic treatment planning
This study of 131 Thai women found that higher dermatologist-rated facial attractiveness is significantly associated with narrower horizontal soft-tissue measurements, such as a smaller nasal base and slimmer lower facial contour, providing population-specific data to inform facial aesthetic and orthognathic treatment planning.

Imagine you are trying to bake the perfect cake. For centuries, bakers have believed there is one single, magical recipe—the "Golden Ratio"—that guarantees a delicious result no matter who you are or where you live. They thought if you just measured your ingredients to this exact mathematical proportion, the cake would be beautiful. But recently, scientists have started to wonder: does this recipe actually work for everyone? Maybe a cake that tastes perfect in Paris needs different spices to taste perfect in Bangkok. This is the big question in the world of facial beauty. For a long time, doctors and artists tried to use one universal set of rules to decide what makes a face attractive. But now, researchers are realizing that beauty might be more like a local dialect than a universal language. It depends on your culture, your background, and the specific features of the people around you. Understanding this is crucial because if a doctor tries to "fix" a face using the wrong recipe, they might accidentally erase the unique charm that makes that person who they are.
This study dives into that mystery, but instead of cakes, the researchers are looking at faces. They wanted to find out what specific facial measurements are linked to attractiveness among Thai women, a group that hasn't been studied much with high-tech tools before. To do this, they didn't just guess; they used a 3D camera system that acts like a digital sculptor, creating a perfect, three-dimensional map of a person's face from five different angles. Then, they asked three expert dermatologists (skin doctors who know a lot about beauty) to look at these 3D maps and rate how attractive they were. The doctors didn't know the measurements; they just used their eyes and experience. The researchers then split the women into two groups: those the doctors rated as highly attractive and those who were just "average" in the study's eyes. By comparing the 3D maps of these two groups, they tried to find the secret "ingredients" that made the attractive group stand out.
Here is what they found, and it's a bit of a twist on the old "perfect face" rules. The study suggests that among the Thai women they looked at, the faces rated as more attractive tended to be a bit narrower and slimmer in specific ways. The "attractive" group had a narrower nose base (the distance between the nostrils) measuring about 19.443 mm, compared to 19.945 mm in the other group. Their lower faces were also slimmer; the width of their jaw angles was about 52.446 mm, while the other group was slightly wider at 53.561 mm. Even the width of their ears (measured from the front of the ear to the back) was smaller in the attractive group, at 65.044 mm versus 66.642 mm.
It's not just about being narrow, though. The study also found some interesting differences in height. The attractive group had slightly shorter distances from the top of their heads down to their eyes and nose, but longer distances from their nose down to their chin and lips. Think of it like a house: the roof and upper walls might be a bit more compact, but the living room and basement are stretched out a bit more. However, the researchers were careful to point out that there were no significant differences in how "deep" or "forward" the faces were; the front-to-back measurements were pretty much the same for both groups.
The researchers also looked at the angles of the face. They found that the attractive group had a sharper, more pointed angle at the jaw (the bigonial angle) and a different angle for how the lower lip projected forward. But here is the most important part of the story: the authors are very clear that they are not saying these measurements are the only way to be beautiful. They aren't rewriting the rules of beauty for the whole world. Instead, they are saying, "Hey, in this specific group of Thai women, these are the features that the experts noticed." They explicitly argue against the idea that there is one universal "Golden Ratio" that applies to everyone. They suggest that beauty is local, and what looks great in one culture might not be the target in another.
The study also peeked inside the "Thai" group to see if there were differences between Thai-Indian, Thai-Thai, and Thai-Chinese women. They found that while the width of the face didn't change much between these subgroups, the vertical heights did. For example, the Thai-Indian women in the attractive group had slightly different vertical measurements for their cheekbones and chins compared to the Thai-Thai and Thai-Chinese women. This reinforces the idea that even within a single country, there is a lot of variety, and a "one-size-fits-all" beauty standard just doesn't fit.
So, what's the takeaway? This paper doesn't give us a magic formula to make everyone beautiful. Instead, it gives doctors and artists a new set of reference points. It suggests that when planning treatments or surgeries for Thai women, aiming for a narrower nose and a slimmer lower face might align better with what is considered attractive in that specific community. But the authors warn that these are just observations from a specific group of women who visited a clinic, not a law of nature. They remind us that beauty is complex, influenced by culture and individual taste, and that the best approach is to understand the unique features of the person in front of you, rather than trying to force them into a generic mold.
