Hyaluronic Acid Gets the Ad Budget. Glycerin Does the Work.
The cheapest humectant on the ingredient list is also the best-studied, the most reliable in dry air, and the one your favorite moisturizer is quietly built around.
It is seventy percent double-fermented Artemisia annua extract with a humectant gel and nothing else: no fragrance, no oil, no essential oils, no extra actives, fifteen ingredients in all. Most calming serums are a soothing extract added to a base; this one is the extract, which is why it has become the product other mugwort serums are measured against.
Seventy percent fermented mugwort, a humectant gel and nothing else: fifteen ingredients, no fragrance, no oil, no gimmick. It calms a flushed face within minutes, hydrates without heaviness, and pairs with every active in the cabinet, which is why it has been the reference calming ampoule since 2019 under two names. Its evidence is preclinical and its ambition stops at soothing, and that is precisely why it works.

Also listed for Rosacea and Acne — the actives here (Mugwort (Artemisia) are in our research queue for those concerns; there is no verdict until their evidence rows are written. That is a gap in our table, not a mark against the product.
A verdict is DermApproved’s assessment of how well a product’s ingredients fit a concern — never a claim about what the product treats. Evidence dots and collected reviews sit beside it and are never blended in. Rules 0.5.1 · evidence table ev-2026.09-r228 · how we decide
Read the list and it is over in fifteen words. Artemisia annua extract first, at a stated seventy percent; then glycerin and butylene glycol, both ahead of the water; then hexanediol, betaine, trehalose, a seaweed extract, sugarcane extract, a carbomer gel, a crosspolymer, tromethamine, a phosphorylcholine polymer, a preservative booster and EDTA. That is the entire Artemisia Calming Ampoule, and it is worth pausing on how unusual it is. Most calming serums are a base with a soothing extract added at a few percent; this one is the extract, fermented and thickened into a gel, and the decision to leave everything else out, no fragrance, no essential oils, no oil at all, no niacinamide or centella or peptides to broaden the claim, is what has made it, since 2019, the product other mugwort serums are compared with. Missha launched it under the Time Revolution umbrella at the height of Korea's mugwort moment, with a story about triple fermentation in urns and low-temperature extraction of artemisia grown on Ganghwa island, and in 2024 it moved the formula unchanged into a standalone Artemisia Calming line with a frosted dropper bottle and a lower price, while continuing to sell the older 75ml Time Revolution bottle beside it for more money. Same fifteen ingredients in both; buy the new one. What it does is narrow and reliable. On a face that is flushed, hot, tight or stinging, from an acid, a retinoid, a shave, a wind, a bad week, a dropperful of the cool amber gel takes the heat down within a few minutes and leaves the skin hydrated and quiet for hours. Used twice daily for a few weeks, reactive skin tends to flush less readily and feel less fragile, which is the cumulative version of the same effect. Oily and combination skin get hydration with no oil and no shine; dry skin gets a humectant layer that wants a cream over it; sensitive skin gets a serum with nothing in it to react to except, in principle, the artemisia itself, which sits in the same plant family as ragweed and can occasionally trouble people with that pollen allergy. The texture is a bouncy water-gel that spreads thin and goes slightly tacky for a minute before setting, and a faint green herbal smell is the only scent. Living with it for a season shows where it fits. In summer it is a morning serum for oily skin that wants hydration without a film, and it disappears under sunscreen; in winter it is the layer under a cream on the nights a retinoid is skipped, and the layer over a face that a cold wind has left raw. It makes an oddly good post-shave step, and a good aftersun on the shoulders as well as the face, where a thicker layer left for ten minutes takes the heat out of a burn faster than aloe gels that cost less and contain more. It has never, in this writer's experience or in the broad record, made anything worse, which is the highest compliment a calming product can receive. The science is honest about its limits. Artemisia annua, the sweet wormwood that gave the world artemisinin, has a growing preclinical literature on skin: a 2025 study in a three-dimensional epidermal model found its extract reduced inflammatory signalling and supported barrier proteins in an atopic-dermatitis-like setting, and 2024 mouse work showed topical artemisia oil calming induced dermatitis. None of that is a human trial of this ampoule, and the brand does not offer one; what the seven-year record offers instead is an enormous body of consistent user experience saying that it calms, which for a fragrance-free soothing gel is the evidence that matters most and the kind a sceptic can reasonably accept. What it does not do is anything else. It will not fade a mark, treat a breakout, firm, brighten or exfoliate, and a buyer who wants a serum that multitasks should look at a different bottle; this one is the calm step, and its value comes from being unarguably that. There are two small annoyances. The tackiness on drying is real and a thin layer minimises it, and the coexistence of two packagings with two prices for one formula is the brand's confusion, not the customer's. At thirty-two dollars list and regularly around twenty-five on the brand's own site for 50ml, two months of twice-daily use, it is fairly priced for a single-purpose serum with a formula this clean and a reputation this earned, and it is cheaper per millilitre than most of the mugwort serums that followed it. Missha has been making affordable Korean skincare for twenty-six years and has produced its share of hopeful, over-named products; this is the opposite kind, a bottle that promises less than it could and delivers all of it, and it deserves the reference status it has held since the first bottle.
The hero actives that drive this product's performance.
| Ingredient | Function | Evidence |
|---|---|---|
| Artemisia Annua (Mugwort) Extract, double-fermented (70%) | The first ingredient, ahead of the water, at a brand-stated 70 percent: the ampoule is essentially a fermented mugwort infusion thickened into a gel, and everything the product does, the calming, the mild antioxidant and anti-itch activity, rests on this one extract and on the fermentation Missha says breaks it into smaller, more available compounds. | Not yet assessed |
| Glycerin & Butylene Glycol | Second and third, listed above the water, which makes this a heavily humectant gel; they are what give a fifteen-ingredient calming ampoule its lasting hydration and its slightly tacky, cushioned feel before it sets. | Established mechanism for Dehydration · established mechanism |
| Betaine & Trehalose | Sixth and seventh, two osmolyte humectants that help skin cells hold water under stress; in a product aimed at irritated, dehydrated skin they add a comfort that plain glycerin does not, and they keep the gel from feeling stripped as it dries. | Established mechanism for Dehydration · established mechanism |
| Chondrus Crispus (Carrageenan) Extract | Eighth, the red seaweed extract that adds a film-forming slip and a little water-binding on top of the carbomer gel, softening the after-feel and helping the ampoule spread thinly over a flushed face. | Not yet assessed |
| Polyquaternium-51 | Thirteenth, a phosphorylcholine polymer used in Japanese and Korean formulas as a moisture-retaining film; it is the quiet reason the ampoule leaves skin feeling hydrated hours later despite containing no oil at all. | Not yet assessed |

serum
AM & PM
After toner and before moisturizer, morning and night; a dropper's worth smoothed over the whole face, or a thicker layer left on a flushed area for ten minutes as a wash-off mask. It sits under any active without conflict and is the serum to keep using on the nights a retinoid or acid is skipped.
Redness and heat ease within minutes of application and the calm lasts for hours; with twice-daily use over two to four weeks, reactive skin tends to flush less readily and feel less tight, while any effect on blemishes is indirect, through lower inflammation, and slow.
With a single active, the science is a single question: what does topical Artemisia annua extract do to skin, and how much of it is here. The concentration question is answered by the label, seventy percent, and by the extract's first position ahead of the water; the fermentation Missha describes, a low-temperature, multi-stage process, is claimed to break the extract's polyphenols and terpenoids into smaller, more soluble fractions, which is plausible but not independently verified. The activity question has a preclinical answer. Artemisia annua contains artemisinin, flavonoids such as quercetin and luteolin derivatives, and chlorogenic acids, with documented antioxidant and anti-inflammatory activity in vitro; a 2025 study in the Journal of Experimental Pharmacology using an atopic-dermatitis-like three-dimensional epidermal model found that Artemisia annua extract at 0.1 to 1 percent reduced inflammatory cytokine signalling, including TSLP, and increased filaggrin expression, a barrier protein, without cytotoxicity, and a 2024 paper in the Journal of Ethnopharmacology reported that topical Artemisia annua essential oil suppressed dermatitis and restored barrier function in a mouse model. Those results support the mechanism behind the calming users describe, reduced inflammatory signalling and barrier support, while stopping short of human trial evidence, and none of them involves this product. The rest of the formula is a humectant delivery system: glycerin and butylene glycol above the water, betaine and trehalose as osmolytes that help cells retain water under stress, carrageenan for slip, and polyquaternium-51, a phosphorylcholine polymer with good data for moisture retention on skin. The absence of fragrance, alcohol, oil and additional actives means the formula has essentially one sensitisation pathway, Asteraceae cross-reactivity, and no comedogenic content, which is consistent with its reputation for tolerance.
Dermatology commentary tends to treat mugwort serums as well-tolerated cosmetic soothers rather than treatments, and this one is the clearest example of the type: a fragrance-free, oil-free, alcohol-free humectant gel whose single botanical has preclinical anti-inflammatory and barrier data and a long record of tolerance. For rosacea-prone, acne-prone and generally reactive skin it is a reasonable daily step, and it is often suggested as a buffer alongside retinoids, benzoyl peroxide and exfoliating acids, since it contains nothing that interacts with them. The cautions are narrow: Artemisia belongs to the Asteraceae family, so patients with ragweed, chrysanthemum or mugwort allergies should patch test, and any product should be stopped if it stings rather than soothes. It is not a treatment for rosacea, eczema or acne, and persistent inflammation or breakouts still need a proper regimen and, where warranted, prescription therapy; a calming serum is the adjunct, not the plan.
After cleansing and toner, morning and evening, dispense a dropper's worth into the palm and smooth a thin layer over the face and neck, pressing rather than rubbing so the gel sets quickly and stays less tacky; follow with moisturizer, and with sunscreen in the morning. Under a retinoid or after an acid, apply it first as the buffer. On a flushed, stinging or sunburned area, a thicker layer left for ten minutes and then patted in or rinsed works as a rescue mask. Patch test on the inner arm if you have a ragweed or mugwort pollen allergy, and keep the bottle out of direct sun.
Thirty-two dollars list, and routinely around twenty-five on the brand's own site, for 50ml that lasts two months at twice-daily use is a fair price for a single-purpose calming serum, and a good one given how much of the bottle is the fermented extract rather than a base. It undercuts most of the mugwort serums that followed it per millilitre and compares well with Western soothing serums that carry fragrance and more filler. The one value trap is the brand's own: the older 75ml Time Revolution pump, still sold, costs more for an identical formula, so the per-millilitre maths favours the new 50ml pack. For anyone whose skin needs calming regularly, it is one of the better-value bottles in Missha's range; for anyone wanting a serum that also brightens or firms, the money buys only soothing, which is the point.
Sensitive, rosacea-prone, acne-prone and combination skin that wants a fragrance-free, oil-free calming serum with a genuine track record, and anyone running retinoids or acids who needs a buffer step with nothing in it to conflict, will find this one of the most dependable bottles in Korean skincare.
Anyone with a known ragweed or mugwort allergy should patch test first, and anyone wanting a serum that brightens, firms or treats breakouts should know this does only one thing. Dry skin will need a proper moisturizer over it, and buyers should choose the 50ml pack over the older 75ml one, which costs more for the same formula.

No added fragrance; a faint green, herbal mugwort note that is gone once the gel sets.
A 50ml frosted glass dropper bottle with a printed sprig of mugwort; the older Time Revolution 75ml bottle is still sold alongside it at a higher price, with the same formula inside.
The first application is unremarkable in the best way: a cool gel, a faint herbal smell, no tingle, and a visible drop in redness within a few minutes on skin that was flushed; there is no purging or adjustment, and the only thing to learn is that a thin layer sets faster than a generous one.
About two months at a dropper twice daily; longer used once a day or as an occasional rescue treatment.
All Year
Missha launched the Artemisia line in 2019, at the peak of Korea's mugwort moment, with a treatment essence and this ampoule built on a triple-fermented, low-temperature extraction of Artemisia annua grown in Ganghwa. The line became a global calming reference within a year, and in 2024 the brand moved it out of the Time Revolution umbrella into a standalone Artemisia Calming range, keeping the formula unchanged and adding a cream and a mist.
Missha, the Seoul brand Able C&C launched in 2000, built its Artemisia line in 2019 on a double-fermented mugwort extract that quickly became one of Korean skincare's reference calming products. The formula has stayed unchanged through a 2024 rebrand from Time Revolution to the standalone Artemisia Calming line; the brand publishes no trial for it, and the mugwort evidence is preclinical.
Mugwort treats acne.
Artemisia annua has anti-inflammatory activity in cell and animal studies, which is why the ampoule calms the redness around blemishes; it has no antibacterial or keratolytic evidence at cosmetic doses and does not treat the breakouts themselves, so it belongs beside an acne treatment, not in place of one.
Because it is a plant extract with nothing else in it, nobody can react to it.
Artemisia is in the Asteraceae family, and people with ragweed or mugwort pollen allergy occasionally react to it on skin; the ampoule is about as low-risk as a botanical serum gets, but a patch test is still sensible for anyone with that history.
Yes. The ingredient lists are identical, fifteen ingredients led by 70 percent fermented Artemisia annua extract; Missha moved the product into a standalone Artemisia Calming line in 2024 and now sells the 50ml new pack alongside the older 75ml Time Revolution pump, which costs more for the same formula.
A dropper's worth after toner and before moisturizer, morning and evening, smoothed over the whole face. On a flushed or irritated area, a thicker layer left for ten minutes and then patted in or rinsed works as a rescue mask; it layers under any active without conflict.
It calms the redness and heat around breakouts, which makes acne-prone skin look and feel better, but it has no antibacterial or exfoliating action and does not treat the acne itself. Use it alongside a salicylic acid, benzoyl peroxide or azelaic acid routine as the soothing step.
Yes, and oil-free, alcohol-free and essential-oil-free too. The faint green herbal smell is the fermented mugwort extract itself and disappears once the gel sets; there is nothing else in the formula to react to.
Yes, it is one of the best serums to pair with them: apply it under a retinoid or after an acid toner to buffer irritation, and keep using it on the nights those actives are skipped. It contains nothing that conflicts with any common active.
For rosacea-prone skin it is among the better-tolerated serums available, fragrance-free and oil-free with a genuinely calming extract. Eczema-prone skin usually does well too, though anyone with a ragweed or mugwort pollen allergy should patch test, since Artemisia is in the same plant family.
