How South Korea Is Changing Tweakments: Even Derms Are Going There For Tweaks!

I was sitting in a North London pub when a man in his late 30s walked in with some of the most radiant skin I’ve ever seen. I couldn’t resist asking him what his secret was (I’m a noisy journalist after all), and his answer might surprise you. He’d just got back from South Korea…

No, this isn’t a story about booking a great holiday to Asia. His serious glow – and that of many dermatologists and skin experts in the beauty industry itself, I’ve since discovered – is, in fact, due to South Korea’s booming tweakment industry.

But, before you jump on a plane, here’s what you need to know (and how to achieve similar results here in the UK)…

South Korea: the silent tweakment powerhouse

As the licensed esthetician (and social media educator) Charlotte Parler shared on Instagram (after her own trip to Korea), Seoul is considered the global cosmetic surgery capital of the world, currently performing 24% of all cosmetic surgeries, according to the Society of Aesthetic Plastic Surgeons. As of 2018, an estimated one in five South Korean women had had cosmetic surgery, with that figure rising to nearly 50% among women in their 20s in Seoul, according to Parler.

With demand comes innovation (and vice versa), so, according to Dr Christine Hall, who is known as the UK’s Korean skincare doctor, South Korea is widely considered to be around 10–12 years ahead of Britain in aesthetic medicine – not just in terms of new treatments, but in how those treatments are approached.

“It’s an industry that’s really growing, and they’re definitely ahead when it comes to innovation and ingredients development,” Dr Hall explained at BCAM’s Conference 2026 which Alice attended. “Perhaps because I’m half Korean myself, I see a lot of patients come to the clinic curious about South Korean treatments…and what’s good for us [in the UK] is that they are so far ahead, we can almost look to see what they’re doing and then select the good bits and bring those over. The UK K-Beauty sector alone is set to grow to $855 million by 2032.”

Why are tweakment insiders heading to South Korea?

But there’s something even more notable happening. The UK beauty market isn’t just taking inspiration from South Korea. Instead, insiders are actively travelling there to have tweaks, too.

“I get a lot of queries about people who are actually going to travel to South Korea to get their treatments done,” affirms Dr Hall.

What’s causing that interest? Social media, of course, is playing a role. As more people document their treatment journeys, South Korea’s reputation for high-quality results is fuelling a surge in medical tourism.

Cost is a major factor as well, as South Korean prices for tweakments are a lot more affordable. Toxin injections, for example, are roughly 40% cheaper in Seoul than in the US, with some clinics advertising treatments for under $100. (Throw in the fact that South Korea is a great place to visit for a taste of a very different culture, and you could argue that you have quite the holiday.

“Tweakment tourism is a growing trend, and I understand the appeal,” says the award-winning aesthetic doctor, Dr Sabika Karim. “Treatments can be more cost-effective, and some patients like the idea of having multiple procedures done in a short space of time while they are away.”

What’s particularly interesting, though, is that it’s not just trend-chasing consumers driving this movement. Respected industry experts are making the trip. Parler herself has visited, as has Dr Ewoma Ukeleghe, who returned after a successful first experience and recommends “using a beauty concierge if you’re looking for the best clinics in Korea.”

The dermatologist Dr Aamna Adel even went viral for sharing her experience, which involved 10 procedures in 24 hours, including facial analysis, a Vampire facial, Theramage Skin tightening, Pico Laser treatment, ‘Baby Botox’, the ‘Rejuran’ salmon sperm facial, and LED light therapy.

She described the experience as ‘painful’, but as with the multitude of other videos you can find on social media, this ‘tweakment stacking’ approach is seriously taking off…

What is tweakment stacking?

First things first, using multiple modalities rather than a single intervention to treat skin concerns is nothing new – and in the UK, experienced aesthetic doctors have been using the technique for years. (We tend to call it a combination treatment).

However, the South Korean market has turned things up a notch. They are now famous for having clients spend not just an hour or two in the clinic, but a full day, so that they can have 5, 10, or even 15 treatments one after another.

In Seoul, it’s particularly common to find many different procedures combined in treatment packages, such as laser for pigment, radiofrequency for tightening, and injectables for texture, meaning you can address a whole range of skin concerns in one sitting.

That does have benefits: “When done correctly, treatment stacking is one of the most effective ways to achieve optimal results,” says Dr Karim. “We age in multiple layers, from the skin itself through to the soft tissues and down to the underlying bone, so treating just one layer rarely gives the best outcome.”

However, stacking works best when it’s strategic, not excessive, and, with the South Korean trend especially, there is a risk of slipping into a routine that’s better for your social media than for your skin.

“Combination treatments, when they’re done properly, are one of the most effective ways of getting really natural, balanced results, and they’re something I use all the time,” agrees clinical nurse director Jen Vittanuova. “But properly usually means they’re planned, sometimes staged and based on a thorough assessment of the person in front of you, rather than being compressed into one appointment for convenience or because it makes good content. For me, it always comes back to the same thing: it’s not about how many treatments you can do, it’s about whether each one has a clear purpose and a clear benefit for that particular patient.”

What tweakments are South Koreans having?

Curious to know exactly what South Koreans are booking in for (tweakment stacking or not)? Here are four tweakment trends that Dr Hall predicts we’ll be seeing more and more of in the UK, too.

1. Micro-tox

Micro-tox is the tweakment that’s often credited with creating the ‘glass skin’ look that everyone seems to be after right now. “Micro-tox is one of the most popular treatments in South Korea,” says Dr Hall. “Rather than injecting into the muscle itself, you are injecting the toxin very superficially, and that helps the skin to glide smoothly over the muscle. We normally double dilute the Botulinum toxin, and sometimes can double dilute with a skin booster, so you are getting a dual treatment at the same time.”

The aim: as well as providing that glowing skin effect that’s so popular, micro-tox helps reduce oil production, makes pores appear smaller, and can help with acne and with rosacea, with some good research to support it, says Dr Hall. It has also been used successfully for fine lines and slight laxity on the neck, with just one session, although you do need to commit to regular maintenance appointments.

2. Rejuran salmon sperm facial 

Polynucleotides – aka the ‘salmon sperm facial’ – have become a global skincare trend, but keep an eye out for one brand in particular, Rejuran. Rejuran is the product you are most likely to find in Korean clinics (and a growing number of UK ones too), and it’s celebrated for getting you the best of the best polynucleotide-based results. That includes banishing dark circles and improving overall skin quality over time,

3. Liquid microneedling 

Liquid microneedling is a K Beauty trend we have actually already covered on the Tweakments Guide – and Dr Hall calls it a treatment to watch. As a quick refresher, liquid microneedling uses spicules normally derived from silica or sea sponges to create micro-channels in your skin; a process that allows active ingredients to penetrate more effectively.

“Liquid micro needling has become very widespread in Korea, and there are in-clinic treatments with higher concentrations of needles and different ingredients, as well as treatments that you can do at home,” explains Dr Hall. “It’s usually a course of five sessions, and you can see improvements very quickly for pigmentation, as well as improvements in texture and tone.”

4. Skin tightening devices like Onda 

It isn’t just treatments for the face that are triggering excitement in South Korea and beyond. Onda, is a body tightening device that Dr Hall is seeing a lot of renewed interest in.

“This is not new technology, particularly, but it’s something that’s becoming extremely popular in South Korea at the moment,” she reveals. “It’s a treatment that can help with excess fat, and it also tightens the skin. So that’s a combination that’s quite unusual. It also demonstrates this shift towards treatments that don’t really give you downtime, that are not too expensive, and that focus on the body too.”

So, what the UK can learn from South Korea about tweakments

It’s not just what South Koreans are having in clinic that matters though – how they approach tweaks in general is going to have a big impact on gloabl approaches, say the experts:

1. A prevention-first mindset

“The overriding thing about aesthetic medicine in South Korea is that it’s definitely more preventative and regenerative, rather than treating the signs,” explains Dr Hall. “So people in South Korea start thinking about treatments in their 20s. Now, personally, I’m not so sure how healthy that is, but certainly, as they get older, the treatments that they have done when they are younger have helped them to stay looking young.”

“What Korea has done exceptionally well is shift the focus from correction to optimisation, investing in skin health early, rather than waiting to treat ageing later,” agrees Dr Karim.

2. Skin quality above all else

Arguably, South Korea’s biggest impact on the UK market is its obsession with skin quality. “South Korea has become hugely influential in both skincare and tweakment approaches, particularly driven by social media trends such as ‘glass skin’ and now the emerging ‘mono skin’ movement, which focuses on clarity, uniform tone and overall skin quality rather than heavy coverage,” says Dr Karim.

That’s feeding hugely into the UK market, as Vittanuova highlights: “You can really see the South Korean influence coming through at the moment, especially on social media, and I think the ‘glass skin’ trend is probably the clearest example of that. Everyone suddenly wants this completely smooth, poreless, almost reflective skin. You only have to walk into somewhere like Boots or Space NK, and you’ll see how quickly Korean skincare has become part of the mainstream. Some of it is genuinely excellent, and I think the focus on skin quality and prevention has been a really positive shift for the industry, but there are doubts about how achievable this actually is!”

Are there reasons to be concerned about the South Korean tweakment boom?

Unfortunately, while there are a lot of positives and innovations coming out of South Korea, there are reasons to be cautious.

1. Body image concerns 

In particular, South Korea’s aesthetic industry exists within a culture of intense beauty standards, and cosmetic procedures are normalised to a degree that can blur the line between choice and expectation.

“There is a huge pressure on Korean culture and society to look good,” says Dr Hall. In fact, “there was something recently called Escape the Corset movement, which is where a lot of young women threw out all of their makeup, refused to do any treatments, and cut their hair very short, saying that they are not going to comply with the societal pressure anymore.”

“I do think we need to acknowledge the wider context that these trends are coming from,” agrees Vittanuova. “South Korea has a very normalised culture around aesthetic intervention and, at the same time, it also reports some of the highest suicide rates among developed nations. That doesn’t mean aesthetics is the cause, but it does reflect a level of societal pressure around appearance and perfection that sits underneath a lot of what we’re seeing.”

2. More isn’t always more

As alluded to above, tweakment stacking can be effective, but there’s also a big risk of taking things too far. A good treatment plan should always be clear on ‘why’ you are having a treatment, ‘what’ it exactly does for you, and ‘how’ it can add to what you are having already.

“The ‘I had ten treatments in one day’ narrative sounds impressive, but from a clinical perspective it raises questions about appropriateness, timing and whether each of those treatments was genuinely indicated,” says Vittanuova. “There’s a difference between a well-planned combination approach and simply layering treatments because they’re trending.”

“Having multiple treatments in one day can also increase the risk of overtreatment, where procedures are performed that may not be necessary or appropriate for that individual,” further warns Dr Karim. “There is also the potential for complications, particularly when combining treatments that may interact.”

3. Beware the marketing

Equally, while these ‘exciting Korean treatments’ might feel new, the reality is that some of that is marketing. “Things like liquid microneedling and microtox are being presented as though they’re entirely new, when in reality they’re often a repackaging or a slight evolution of techniques that have been around for a while,” says Vittanuova. “That’s not necessarily a problem in itself, but it does mean the marketing can sometimes run ahead of the clinical explanation, and patients aren’t always getting the full picture of what those treatments are actually doing in the skin.”

4. You don’t have to get on a plane!

Finally, choosing to have tweakments in South Korea isn’t a problem in itself, but you do have to be careful about continuity of care with any type of tweakment tourism. “If something goes wrong, it can be difficult to access follow-up treatment or manage complications once you are back in the UK,” warns Dr Karim.

And ultimately, despite what social media might say, you really don’t have to go to South Korean itself to get great tweakment results!

“Patients can absolutely achieve comparable results in the UK by seeing the right practitioner, someone who can assess their individual needs and create a tailored, medically led treatment plan,” continues Dr Karim. “You don’t need to travel, you just need the right expertise and a thoughtful, layered approach to treatment.”
