Where Should You Open Next? Three Findings From Data on 2,600+ Aesthetic Clinics Across Bangkok

"Where should the next branch go?" is a question that eventually lands on the desk of almost every clinic owner who has already gotten the hard parts right: built a service people want, and found the marketing that brings new faces through the door. Opening another branch is often the only way to actually meet the demand that is already showing up. So to help clinic owners think it through, we pulled together and analyzed location data on more than 2,600 aesthetic clinics across Bangkok.

Interactive map: every aesthetic clinic in our Bangkok dataset. Zoom in and click a cluster to explore individual clinics.

We wanted to see where clinics actually cluster, which districts are crowded, which are thin, and, most importantly, where the brands that have genuinely managed to expand have chosen to plant themselves. This is not us telling anyone how to run a clinic. But the dataset reflects something quite valuable: a picture of how thousands of clinic owners, people who put their own money on the line, have already made their location decisions. Out of all of it, three findings stood out enough that we wanted to share them.

Finding 1 — Bangkok isn't one market. It's two worlds.

The first thing the data tells us is that the aesthetic clinic market in Bangkok is spread wide. It is not packed into the city center the way many people assume. Across all 49 districts, the single most clinic-dense district still holds only about 3.5% of the market, and you have to combine the twenty largest districts just to account for half the clinics in the city. In plain terms, demand for aesthetic services in Bangkok is everywhere, not tied to a handful of central neighborhoods.

But when you look closer at who sets up where, two very different worlds come into focus. The cleanest way to tell them apart is the share of clinics that belong to a chain (a brand with three or more branches) in each district.

The first world is the brand-name city center. Pathum Wan, Dusit, Bang Rak, Bang Na, Bang Kho Laem: the neighborhoods where the big chains cluster tightly. In Dusit, roughly one in three (33%) clinics is a chain. Pathum Wan sits at 24%, and Bang Rak and Bang Na are around 19%. This is the world of clinics on mall floors, prime spots next to the BTS, and competition fought on brand name against customers who are looking for premium-tier credibility.

The second world is the outer ring of residential neighborhoods. Lat Krabang, Min Buri, Bang Khen, Bang Phlat, Sai Mai, Don Muang. This is where it gets counterintuitive, because these districts actually hold the highest number of clinics in Bangkok. Lat Krabang alone has around 93 clinics, more than the Siam area in Pathum Wan (85). Yet the chain share is tiny: Lat Krabang at 6%, Min Buri at 7.5%, Sai Mai and Don Muang at just 3%. Almost all of them are independent clinics serving their immediate community.

What is striking is how sharp the line between the two worlds is. Among the most clinic-heavy districts, almost none sit in the middle. They split cleanly into a "chains above 15%" group and a "chains below 10%" group. These are two entirely different games. The city center is a contest of brand and image on turf the big players already own. The outer ring is a market built on the residential community, on convenience and familiarity, and it favors clinics that genuinely understand the people in that neighborhood.

So the question a clinic owner should ask first is not simply "which district is good," but "which world is my clinic built for." Taking a clinic designed for one world and dropping it into the other is a risk you cannot see with the naked eye, but the data makes it visible.

And within that outer world, the data points to one gap worth watching especially closely: the Min Buri district.

Min Buri is one of the most clinic-dense districts in Bangkok, ranking 4th out of 49 (around 80 clinics), which tells you it is a large market. But what jumps out is that the average review score in Min Buri is the lowest among the major districts, sitting at about 4.47 (across 74 rated clinics), noticeably below its peers. Bang Na is at 4.80, Chatuchak at 4.82, and even Lat Krabang, the district with the most clinics, holds 4.74. In a market where scores are bunched up near the ceiling (over 40% of clinics citywide sit at a perfect 5.0), a district averaging 4.47 stands out clearly.

What makes the signal more credible is that review manipulation usually pushes scores up, not down. So an average that stays low despite that upward pressure, together with a couple of other large districts showing a milder version of the same pattern (Thung Khru at 4.54, Chom Thong at 4.51), suggests this is not a one-district fluke.

Translated into opportunity, Min Buri is a market that is large and crowded, but where the average standard of service is still soft. That is exactly the kind of gap an operator who genuinely delivers on quality and customer experience can step into and stand apart. (In the interest of being straight with you: two smaller districts, Nong Chok and Bang Bon, score slightly below Min Buri, but with only about 19 clinics each, the sample is too small to draw as firm a conclusion as Min Buri offers.)

Finding 2 — The chains that can expand have already voted on the best locations.

If you want to know which locations the market considers high-potential, the most direct method is to see where the operators who have expanded the most, the ones who put real money at risk again and again, have chosen to open. Because every branch they open is a bet they have already run the numbers on.

Rank the districts by chain share and a clear concentration appears: Ratchathewi (51%) leads, followed by Dusit (33%), Bang Kapi (30%), Bang Khae (25%), Pathum Wan (24%), and the Bang Rak, Chatuchak, Bang Na cluster around 19%. These are the neighborhoods chains have decided to enter time and time again. On the flip side, several districts are almost untouched by chains, including Chom Thong, Huai Khwang, and Bang Sue at 0%, even though some of them have plenty of clinics.

But the most interesting part of this finding is that "where the chains go" is not "where the clinics are." Ratchathewi has the highest chain share at 51%, yet only 45 clinics, because it is a cluster of head offices and BTS-adjacent locations. Meanwhile the districts with the most clinics, Lat Krabang and Min Buri, have very few chains. That means chains and independents are working from two different definitions of "a good location." Chains pick strategic points that serve the brand and access, while independents follow the customer base in the community they already live in.

And the chains do not all play the same game. Some go wide, spreading across the city, like Gangnam and Apex, each with branches in roughly 14 to 15 districts. Others go deep in just a few locations, like Rajdhevee with 28 branches concentrated in only 7 districts, or Masterpiece with 10 branches focused on just 2. Both strategies have their logic, and both show that grown-up clinics think seriously about how they lay out their branch network.

You can read this two ways. For a cautious owner, chain concentration is a signal that a location has been validated and the risk is lower, because the big players have already invested to confirm it. But the same data also says that the dense outer-ring districts with no chains yet are open ground where you do not have to fight the big brands at all. Which game you want to play is up to you.

One closing note that matters: when you compare chains to independents, the average review scores are almost identical (chains 4.80 vs independents 4.71), but chains have roughly 8x more reviews. What makes a chain a chain is reach, not a better rating.

All of this confirms that the beauty market is fiercely competitive. Whichever game you play, who leads it comes down to your product, service, marketing, location, and, critically, how fast your admin replies. Getting information to an interested customer as quickly as possible, and moving them toward a decision as quickly as possible, is where success is won or lost. An admin that answers 24 hours a day, 7 days a week, in multiple languages, to meet every kind of need, is not optional.

That is why Aira built an AI chatbot specifically for aesthetic clinics: one that helps close the sale, goes beyond a typical chatbot, answers around the clock, and speaks 50+ languages. You can test what Aira's AI chatbot can do right here: airaagent.co

Finding 3 — Running multiple branches is anything but easy.

The last finding may be the one that shifts your perspective the most. Looking at the whole market, we found that more than 9 in 10 clinics in Bangkok operate a single branch. Of roughly 2,359 brands, 2,257 (95.7%) have never opened the door to a second location.

And the higher you climb, the thinner the numbers get, fast, like a funnel narrowing to almost nothing.

The concentration is surprisingly low, too. The 10 largest chains combined hold just 6.2% of the market, and the biggest brand of all, Rajdhevee with 28 branches, accounts for only about 1%. Unlike convenience stores or restaurant chains, where a few brands own nearly everything, Bangkok's aesthetic clinic market is still highly fragmented, with no one dominating.

This matters because it changes the meaning of the original question. Expanding is not the normal path of a successful clinic. It is a rare and deliberate step. Most people who run a good clinic still choose to stay at one location. So when a clinic decides to cross that line, especially when it can expand again and again, that is a meaningful bet. And that small group of clinics that pulled it off is the closest thing this market has to an answer about which locations, and which ways of expanding, actually work.

From the Right Location to a Real Customer

These three findings help answer where to set up and how the market thinks about each location. But they leave the other half of the question unanswered, the half a map cannot solve: once you open in the right neighborhood, how much of that neighborhood do you actually convert into paying customers? Especially when every branch you open carries a high cost and is a bet you do not make often.

There is one fact the citywide data keeps confirming. When nearly every clinic earns a similarly high rating (over 40% sit at a perfect 5.0), your review score no longer makes you stand out. What decides whether a new branch fills up has moved to the experience and the speed of care from the very first message. Because in reality, a customer who is deciding rarely walks in first. They message you first: asking the price, asking which doctor, asking if this Saturday is free. The clinic that replies faster, at any hour, and in the customer's own language is the clinic that turns local opportunity into a real booking.

This is where Aira comes in: an AI assistant that handles customer conversations specifically for aesthetic clinics. It answers every incoming message the second it arrives, 24 hours a day, with no days off, in multiple languages, and it carries that conversation all the way to a booked doctor's consultation. Put simply, once the data helps you choose the right location, Aira is what keeps every opportunity that location creates from slipping away in between, whether your team is busy, it is after hours, or the customer is from abroad.

Deciding where to expand does not have to start with a guess. The market has already sketched much of the answer: the two worlds you have to choose between, the locations the chains have validated for you, and the reality that running multiple branches is rare and deliberate. What is left is to choose the path that fits what your clinic actually is, and then make sure every opportunity a new branch creates gets turned into a real customer.
