The K-beauty trend everyone is buying into right now is centuries older than snail mucin or glass skin. It’s called hanbang, the tradition of Korean herbal medicine, and it quietly sits behind some of the most loved products on the shelf, from Sulwhasoo’s luxury ginseng line to the Beauty of Joseon serum that seems to live in half the routines online. Our read is that hanbang is neither ancient magic nor empty marketing. It’s a group of really interesting plant ingredients, like ginseng, mugwort, rice, licorice root and heartleaf, wrapped in a heritage story brands love to tell. A few of those herbs have solid research behind them, while others lean more on tradition and a pleasant feel, and knowing which is which helps you shop smart.
What makes a product hanbang
Hanbang means traditional Korean herbal medicine, a system of plant remedies going back centuries and written down in texts like the Donguibogam, an old Korean medical encyclopedia that brands love to mention. In skincare, it means formulas built around medicinal herbs that were traditionally brewed, simmered or fermented, such as ginseng for vitality, mugwort for calming and licorice root for a clearer-looking complexion.
It isn’t a regulated term, though, and there’s no certification that makes a product “real” hanbang. A brand can steep a single herb in a watery essence and print a Korean character on the bottle. The established houses, like Sulwhasoo, Hanyul and The History of Whoo, put real money into herbal research and traditional processing, while smaller brands borrow the look to different degrees. Neither approach promises better skin, but it helps to know the difference when you’re wondering whether a high price is paying for the formula or the story.
Ginseng, mugwort and the other signature herbs
Here’s a quick tour of the herbs you’ll see most, along with a fair sense of how much evidence each one has.
Ginseng. This is the star, especially red ginseng, which is steamed before it’s dried. Its active compounds, called ginsenosides, show antioxidant activity and may support firmer-looking skin and better circulation. Most of the exciting data comes from lab work and small human studies, often paid for by the brands selling it, so file it under promising rather than proven. What ginseng products reliably give you is a rich, cushiony feel that dry and mature skin tends to love.
Mugwort. This is the soothing one, and our favorite of the group. Mugwort extracts, also called artemisia, appear to calm inflammation and fight oxidative stress, and the herb has become a go-to for stressed, reactive skin that’s been over-exfoliated. If your skin is angry from too many acids, a mugwort essence is one of the gentlest ways to settle it down. Our mugwort skincare guide has the full story.
Rice. The traditional story is a sweet one, since women at the Korean royal court reportedly washed their faces with rice water, and the modern case is decent too. Rice bran carries ferulic acid and other antioxidants, and rice extracts may help with brightness and hydration. It won’t outdo a dedicated vitamin C, but as a gentle glow ingredient for sensitive skin, it does its part.
Licorice root. Of all these herbs, this one probably has the best support for brightening. A compound in it called glabridin has been studied for slowing the enzyme that makes extra pigment, and over time it can gently fade post-breakout marks and even out tone. Dermatologists often suggest it for sensitive skin that can’t handle stronger brighteners, which is a better endorsement than most plant extracts get.
Heartleaf. The newest favorite, also known by its Latin name Houttuynia cordata, shows up everywhere in products for oily and breakout-prone skin. Tradition treats it as a purifying herb, and modern research points to soothing, anti-inflammatory effects. The human data is thin, but people’s experience with it is consistent: heartleaf toners like Anua Heartleaf 77% Soothing Toner are light, calming and very unlikely to irritate, which makes one an easy first hanbang step for oily skin. Expect low risk and a modest payoff.
You’ll notice most of these land in the same place, offering antioxidant support, soothing and a little brightening. Hanbang herbs play a supporting role rather than the lead. None of them will resurface skin like a retinoid or clear acne like benzoyl peroxide, and no trustworthy brand claims they will. They aren’t medicines, whatever the tradition suggests, so if you have an actual skin condition, a dermatologist is the right call rather than an essence.
Why fermented herbs feel different
If hanbang has one signature technique, it’s fermentation. Traditional Korean herbal preparation often involved fermenting plants, and modern brands have run with it, putting fermented ginseng, fermented rice and yeast ferments like galactomyces and bifida into everything from essences to creams.
The reasoning holds up better than most heritage claims. Fermentation breaks compounds into smaller pieces, which may help skin make use of them, and the process can create amino acids and peptides that weren’t in the original plant. It’s a bit like how yogurt can be easier on the stomach than plain milk. Skin isn’t a stomach, of course, and the absorption angle gets overstated in ads, but fermented extracts do tend to be gentler and richer than their raw versions. Missha Time Revolution First Treatment Essence is a good way to try one without luxury prices, since it’s over 90 percent fermented yeast extract. Our fermented skincare guide covers the science and the standout products.
Four houses behind the hanbang revival
Four names come up again and again, and they sit on very different shelves.
Sulwhasoo is the prestige house, the ginseng-focused flagship of Amorepacific, with decades of ginseng research behind it and prices to match. Its First Care Activating Serum is the icon, a silky, faintly herbal essence you smooth onto bare skin before anything else. It isn’t six times better than a drugstore essence, but it’s one of the most pleasant products we can think of.
Beauty of Joseon made the tradition affordable. It took old Joseon-era beauty lore, like rice water, ginseng and herbal remedies, and paired those heritage ingredients with well-known modern actives, such as rice with arbutin and ginseng with retinal. The Beauty of Joseon Glow Deep Serum pairs rice bran water with alpha arbutin for under $20, which makes it the smartest hanbang buy around, and the Beauty of Joseon Glow Serum uses propolis and niacinamide for a calm, honeyed glow on dehydrated combination skin that still breaks out. That mix is clever, and it’s a big reason the brand won over so many skeptics.
Hanyul stays closer to its apothecary roots, with lines built around single herbs like artemisia and rice at a mid-range price. It’s less famous in the West and really good at what it does, and its Hanyul Pure Artemisia Calming Essence is a touch more elegant in texture than the purist mugwort options.
I’m From is the purist of the group. Its whole idea is a high concentration of one Korean-grown ingredient, and the I’m From Mugwort Essence is 100 percent artemisia extract from Ganghwa Island, with nothing else hiding in the bottle.
How hanbang feels next to retinol and acids
You’ll notice the difference in the first week. Western actives make themselves known, since retinoids can cause a purge, acids tingle and vitamin C can sting on irritated skin. Hanbang products mostly don’t do any of that. They come as essences, watery serums and cushiony creams made for layering, and the whole approach is comfort that builds over time rather than a quick shock.
That makes them very easy to fit into a routine. Heartleaf and mugwort sit happily under a retinoid, and a fermented essence slips right in between cleanser and vitamin C. The only real clash is in expectations. If you want every product to show a clear before-and-after in four weeks, hanbang may test your patience, because its promise is that calm, well-cared-for skin looks better over months. Both ideas can live in the same routine, and modern Korean routines do exactly that.
Adding a single herbal step
After discovering hanbang, it’s tempting to rebuild your whole routine around it, but there’s no need. Keep your cleanser, your sunscreen and the actives that already work for you, and add one hanbang step wherever your routine has a gap.
If your skin is reactive or over-exfoliated, that gap is soothing, so try a mugwort or heartleaf essence right after cleansing. If your skin looks dull but tolerates just about anything, a rice or fermented essence can add some glow. And if you’re dry and everything feels too thin, a ginseng cream as your last step is the coziest way into the category. Give one product two to three months before you decide, which is a fair and fairly cheap trial.
The heritage and the hype
Hanbang is a bit of both, and that’s okay. The heritage is real, since these herbs have centuries of recorded traditional use and the fermentation methods are distinctive. The hype is real too, because “royal court secrets” is a story rather than evidence, and some brands price their products like the story is the main ingredient. Where research exists, it points to modest, pleasant benefits like antioxidant support, soothing and gentle brightening, delivered in some of the nicest textures in skincare.
That’s still a compliment. Most of us don’t need one more harsh active so much as calmer skin and a routine we enjoy doing every night, and hanbang is unusually good at both. Plant-based doesn’t mean allergy-free, though, so patch-test anything new and see a dermatologist if irritation sticks around.
