Dermatologist vs Influencer Skincare in Singapore: Whose Recommendation Actually Gets Bought?
A participant in her late thirties brought her bathroom shelf to a session in a canvas tote. We ask for this sometimes, and most people bring three or four favourites. She brought everything. Before anyone prompted her, she split the bottles into two piles on the table, one for "things I saw on Instagram" and one for "things the doctor said can use". The Instagram pile was bigger, and much fuller. The doctor pile was smaller and almost empty, because she had actually used those bottles to the bottom (two of them were on their third refill). That table seems to hold the whole argument of this post in two piles of plastic.
Here's the tension. Skincare marketing budgets in Singapore flow heavily toward creators, and for good reason, because creators are where people first meet a product. But the recommendation that keeps a bottle in someone's routine, the one that turns a trial into a refill, appears to come from somewhere else. Across our skincare focus groups on why Singaporeans trust one serum over another, women past their early thirties in particular describe influencer content as a shop window and a doctor's word as permission. This post looks at why that split exists, where each voice actually earns its keep, and how a brand can find out which one its own category runs on.
Where trust starts, according to the numbers
Discovery is where influencers are strong. YouGov's 2025 report on Singapore skincare shoppers found that 52 per cent of skincare consumers discover new products through Instagram. Nobody in our sessions disputes it. What they dispute is what happens next.
Now look at how many people in Singapore have a reason to see skin as a medical matter. HealthHub's eczema guidance says about 20 per cent of school children in Singapore have eczema, and that 30 to 40 per cent of them may still have symptoms as adults. I read that twice. A large share of adult shoppers grew up with a GP or a skin specialist telling their mothers which moisturiser to buy, and which ones to avoid (usually anything with fragrance). That early training does not disappear when a creator posts a glass-skin routine. And households are spending more on health generally. The SingStat Household Expenditure Survey 2023 reports that health spending had the largest increase of any category, 8.1 per cent a year between 2017/18 and 2023, rising from $320 to $474 a month on average, mainly from outpatient care. Skincare is not in that line (and I don't want to over-read it), but it points to a population used to paying for professional advice about its body.
So why does a doctor's word outlast a creator's, once the bottle is open?
Why a white coat carries extra weight in Singapore
Part of the answer is regulation, and consumers here understand more of it than brands assume. HSA's regulatory overview of cosmetic products explains that a cosmetic usually needs a product notification before sale, and that it cannot claim to prevent or treat a disease or change a physiological process. More than one participant has put this to us in plainer words. "Cream is cream. If it can really cure, it's medicine already." So the moment a skin concern feels medical (a flare, pigmentation that won't fade, acne that leaves marks), a shopper knows the jar is legally not allowed to promise the fix she wants. Somebody else has to make that promise, and in her mind that somebody is a doctor.
The second part is fear, and it is well founded. HSA's May 2026 advisory on whitening and anti-ageing products describes cosmetics sold through e-commerce platforms, shops, and social media that turned out to contain mercury (one at nearly 50,000 times the permissible limit), a potent steroid, hydroquinone, and tretinoin. A 2024 case reported by Mothership started when a woman grew suspicious because an underarm cream worked too well, too fast. I think that story circulates in group chats for a reason. It teaches people that dramatic results on camera can be a warning sign, which is exactly the kind of proof an influencer is best at supplying.
The third part is disclosure. The ASAS guidelines for interactive marketing and social media require that a connection between an endorser and a marketer, where it could affect the credibility of the endorsement, be fully disclosed. That is good practice. It also means every sponsored post carries a small label telling the viewer she is being sold to. Doctors, by contrast, are boxed in from the other side. The Ministry of Health explains that paid testimonials and endorsements for licensed healthcare services are prohibited, because readers treat reviews as genuine personal opinion. Consumers may not know the rule. They do sense the scarcity it creates. A dermatologist's recommendation feels hard to buy, and so it feels worth more.
Mapping recommendations by what is at stake on the face
We went in expecting the line to fall between generations, creators for the young and doctors for everyone else. The shelf exercise never drew that line. Actually, the product matters more than the birth year. The same woman who buys a lip tint off a TikTok video will refuse a retinol serum until someone with a medical licence says yes. What changes is how much she thinks could go wrong, and whether the result is something other people will see. The Skin Stakes Matrix below plots exactly that, though I suspect the axes will need adjusting as we test it in more categories.
The Skin Stakes Matrix
White-Coat Territory is where the pharmacy brands live, and their Singapore sites say so openly. CeraVe's Singapore page leads with "developed with dermatologists", and La Roche-Posay's Singapore site cites an IQVIA survey of dermatologists in 43 countries for its "N°1 dermatologist recommended" line. You can find both on Guardian's La Roche-Posay shelf, which matters (a pharmacy chain carries a faint clinical halo that a beauty hall does not). This is also where our in-home research on what "sensitive skin" means in Singapore's climate keeps landing.
Contested Ground is the interesting quadrant, and probably the most profitable. Here a creator's before-and-after is persuasive and suspicious at the same time. Brands that do well here tend to borrow a coat. Sephora Singapore describes Dr.Jart+ as a skin barrier brand "inspired by Korean dermatologists", sold in a store built for discovery. It sits at the seam between the two voices, and I think that is deliberate. Creator Territory and the Habit Shelf matter less to this argument, though the Habit Shelf is where the splurge-or-save calculation for everyday products quietly does most of the work.
What people say about recommendations, and what their shelves show
Ask directly and most participants give a tidy answer. Watch what they have actually kept, finished, and repurchased, and the answer gets more interesting.
| What participants say | What the shelf and the story show |
|---|---|
| "I don't really trust influencers" | Most of the products they tried this year were first seen on a creator's feed |
| "I only use what my dermatologist recommends" | The recommended moisturiser is used faithfully, while serums and masks come from everywhere else |
| "Reviews help me decide" | Reviews decide the shade or texture, a professional decides whether it goes on problem skin |
| "I buy whatever is on promotion" | True for cleansers and body care, rarely true for anything used on a flare or pigmentation |
| "Doctor brands are too expensive" | Price is forgiven once a doctor names the product, especially after a bad reaction |
That last row matters for pricing. Once a professional has named a product, the shopper stops comparing it against cheaper options (at least, that's my reading of how people describe it), which is a very different purchase from the one we traced in what drives a $200 serum purchase. It is also why the gap between stated and actual behaviour runs so wide here. People are telling the truth about their values. They are just describing the moment of commitment and forgetting the moment of discovery, a pattern we see well beyond skincare, and one I wrote about in why Singapore consumer research keeps misleading brands.
The doctor who is also an influencer
Of course the two voices are merging. The Singapore Women's Weekly list of TikTok dermatologists included Dr Teo Wan Lin, who runs a skin clinic here, and plenty of Singapore shoppers now get their "doctor's opinion" from a phone. A 2024 paper by physicians at the National University Hospital, "The rise of medical influencers", argues that doctors on social media can improve health literacy and correct misinformation, and also warns that some use their platforms to advertise private practice or medical products. And the misinformation cuts the other way too. An aesthetic doctor told Vogue Singapore that teens come into her clinic asking for botox, mostly influenced by TikTok videos.
So does the doctor-influencer get the best of both? I assumed so. Let me rethink that, because it holds only some of the time. Participants rate a dermatologist's educational content highly and then discount the same dermatologist the moment a product link appears, especially when the product is the clinic's own line. "Then she also selling what," one woman said, and the room laughed and nodded. Trust seems to attach to independence more than to the credential itself. A doctor who sells becomes, in the shopper's mind, a better-qualified influencer. Useful, sometimes persuasive, but no longer a second opinion. I'm still working through what that means for brands that pay for professional partnerships, and I suspect the answer differs sharply between Contested Ground and White-Coat Territory.
How to research trust without asking about trust
If you ask Singaporeans whom they trust, you get the answer that sounds responsible. So we rarely ask. In focus groups (built on the same Singapore consumer research expertise we apply across categories) we work from objects and histories instead. The shelf exercise above is one version. Another is a product obituary, where each participant tells the story of a product she stopped using, who introduced it, and who (or what reaction) ended it. The endings are where the doctor shows up.
Worth stealing for your own discussion guide: "Pick up the product you would replace last if money got tight. Tell me who first told you about it, and who told you it was safe to keep using." The two answers are often different people, and the gap between them shows you which voice opens the door and which one keeps it open.
The sensitive stories (a steroid cream that thinned the skin, a reaction before a wedding, acne that affected someone's confidence at work) come out better one to one, which is why we pair groups with in-depth interviews. And when a brand wants to know what dermatologists themselves think of its claims, the method changes again. Getting doctors to say what they actually think requires a different recruitment approach and a far more careful discussion guide. Younger shoppers need their own sample too, since Gen Z skincare behaviour leans harder on creators across more of the matrix. And imported brands face a version of this with a head start working against them, as our work on why K-beauty dominates Singapore suggests.
Creators open the door, and the doctor decides who stays
Let me put that more plainly for anyone setting a marketing budget. Influencer spend is probably not wasted, because it fills the trial pile, and a product nobody has heard of cannot be recommended by anybody. But if your product sits in White-Coat Territory or on Contested Ground, the refill depends on a quieter signal that no campaign can fully buy, a professional's permission, a pharmacy shelf, a reaction that never happened. Brands that treat those two jobs as one tend to over-spend on discovery and then wonder why repurchase sags. I doubt the matrix above is the final shape of this (it will shift by skin concern and life stage). That tote bag on the table made the point better than any chart could, with its half-empty bottles that someone, at some point, had been told were safe.
