Beta-Glucan Does Niacinamide's Job Without the Marketing Budget
It hydrates, calms, and quietly supports the barrier with one of the better safety records in skincare. So why has almost nobody heard of it?
It's the same thoughtfully built Supple Preparation base — MSM, centella, licorice, beta-glucan — with the essential oil blend removed and no substitutes layered in to compensate. Klairs didn't quietly reformulate or add a different fragrance; they stripped the top notes out entirely. For reactive skin, that's a rare kind of honesty in skincare.
The unscented sibling of Klairs' cult toner is arguably the better product — same soothing MSM-and-centella base, none of the essential oils that made the original a gamble for reactive skin. It's become a go-to recommendation in rosacea and sensitive-skin communities for good reason, and at the same price as the scented version, there's very little argument for picking the other one.

Most of the time when a brand releases an unscented version of a popular product, it feels like a hedge. They've gotten enough complaints about fragrance that they put out an apology SKU, usually with slightly inferior performance, sold in a quieter package. Klairs did the opposite here. The Supple Preparation Unscented Toner is the same thoughtful MSM-beta-glucan-centella base as the original, stripped of the lavender-citrus-geranium oil blend and nothing else swapped in. No new preservative, no extra filler, no quiet dilution. You can compare the two INCI lists line by line and see that this is just the better formula for anyone whose skin reacts to fragrance.
That distinction matters because MSM — dimethyl sulfone — is actually a pretty interesting soothing ingredient for reactive skin, and the original Supple Preparation Toner was undermining its own selling point by pairing that soothing story with a bouquet of essential oils known to irritate the exact people MSM was supposed to help. Putting a rosacea sufferer in front of lavender oil is like putting a lactose-intolerant person in front of a cheese board and telling them the salad underneath is dairy-free. Klairs eventually figured this out, and the unscented version is the result.
On skin, it behaves the way the scented version does without any of the sensory cues. There's no scent, no tingle, no temperature change beyond the cool of a room-temperature liquid going onto damp skin. It absorbs in about thirty seconds, leaves the same cushiony non-tacky finish, and slots into a routine as a preparation step before essence or serum. For people who've spent years wondering what a Korean hydrating toner is supposed to feel like but couldn't use any of the popular ones because of fragrance — this is the answer.
The ingredient story is built around a soothing trio that has real mechanistic backing. Dimethyl sulfone sits unusually high on the INCI and delivers organic sulfur that multiple studies have linked to NF-κB pathway modulation, which translates in plain English to 'calms inflammation.' Centella asiatica brings its well-documented madecassoside content, which supports collagen synthesis and barrier repair. Licorice root contributes glabridin, a compound with both anti-inflammatory and mild tyrosinase-inhibiting activity — useful if your reactive skin is also dealing with post-inflammatory marks. Beta-glucan, sodium hyaluronate, panthenol, and a grab bag of amino acids handle the hydration side. Copper tripeptide-1 makes a trace appearance at the tail of the list, more of a bonus than a dose, but its presence is consistent with the thoughtful construction of the rest.
Performance for sensitive skin is where this product earns its reputation. Users with mild rosacea, perioral dermatitis, or post-treatment redness report a consistent calming effect within a week or two of twice-daily use. That's consistent with the soothing actives story and isn't surprising. What's more interesting is how well it holds up as a general hydrating toner for people who don't have sensitive skin — the cushiony finish and the ingredient sophistication make it a perfectly reasonable everyday choice even if fragrance isn't a dealbreaker for you. In fact, knowing what we know about cumulative sensitization, choosing the unscented version when you have the option is a defensible baseline regardless of your current reactivity.
There are a few small gripes worth raising. The packaging is nearly identical to the scented version — same frosted bottle, same flat cap, same silhouette on the shelf — which means if you buy both and store them in the same cabinet, you can grab the wrong one without noticing. The pour cap is also a little imprecise; pumps would be better for controlling dispense, though the workaround is to tilt carefully rather than inverting fully. And while the 180ml bottle is a generous size, there's no larger option for people who want to bulk-buy.
Value is excellent. At around $22 for 180ml — same price as the scented version in most markets — this is one of the most cost-effective hydrating toners you can buy for sensitive skin. A bottle stretches three to four months with twice-daily use on face and neck, which works out to about six dollars a month. For a product that a lot of derm-adjacent voices actively recommend for rosacea and barrier repair, that's a strong value position. Comparable fragrance-free hydrating toners from Western sensitive-skin brands routinely cost more for less interesting formulations.
The recommendation is simple. If you have any degree of fragrance sensitivity, rosacea, eczema, or a history of reacting to popular K-beauty products for unclear reasons, buy this one instead of the scented version. If you have robust skin and love the herbal scent of the original, that one is also fine — but there's no formulation penalty for choosing the unscented as a default. It's the quieter, smarter pick, and it's become a sensitive-skin staple for reasons that hold up to scrutiny.
The hero actives that drive this product's performance.
| Ingredient | Function | Evidence |
|---|---|---|
| Dimethyl Sulfone (MSM) | The same unusually high MSM content as the scented version, providing organic sulfur that calms reactive skin — but here it's free of the essential oils that would irritate the rosacea and fragrance-sensitive users MSM is most useful for. | Not yet assessed |
| Beta-Glucan | Partners with sodium hyaluronate and panthenol to deliver humectant hydration in a form that stays cushiony on the skin — especially important in a fragrance-free product where the comfort factor has to come from texture rather than aromatics. | Not yet assessed |
| Centella Asiatica Extract | Works with licorice root and MSM as the calming core of this formula. In the unscented version, centella's soothing effect is the headline benefit rather than a supporting note, since nothing fragrant is competing for attention. | Limited for Rosacea |
| Licorice Root Extract | Adds anti-inflammatory and subtle brightening activity via glabridin, giving the unscented formula a gentle glow-supporting angle appropriate for post-acne skin that can't tolerate stronger actives. | Limited for Rosacea |
| Sodium Hyaluronate | Provides the water-binding backbone of the preparation step. Paired with the other humectants here, it leaves skin primed to absorb the essence or serum that follows without any tackiness. | Established mechanism for Dehydration · established mechanism |
| Panthenol | Provitamin B5 that supports barrier repair and hydration, reinforcing the formula's sensitive-skin positioning without adding anything that might irritate reactive types. | Established mechanism for Dehydration · established mechanism |

AM & PM
Apply to damp skin after cleansing. Press in with palms and layer the next step while skin is still slightly wet. Safe to use immediately after professional treatments or microneedling.
Soothing effect is immediate on reactive skin. Over 2-3 weeks of consistent use, barrier-compromised skin usually feels calmer and less tight. Full benefits for conditions like mild rosacea typically appear around 6 weeks.
The soothing ingredient story in this toner is built on a stack of ingredients with varying but credible evidence. MSM (dimethyl sulfone) has documented anti-inflammatory activity through the NF-κB pathway, outlined in a 2015 review in Nutrients, with smaller topical studies showing erythema reduction in rosacea-like conditions. Centella asiatica has a robust literature base — a 2012 review in the Indian Journal of Pharmaceutical Sciences summarized its triterpenoid-driven wound healing and barrier repair activity, and more recent dermatology work has validated madecassoside as a post-procedure calming agent.
Licorice root extract contributes glabridin, a compound studied for both anti-inflammatory effects and mild tyrosinase inhibition. Research in the International Journal of Molecular Sciences has documented glabridin's relevance in conditions involving both inflammation and post-inflammatory pigmentation — making it a particularly appropriate addition to a sensitive-skin product that also needs to address the marks left behind after breakouts calm down.
Beta-glucan rounds out the soothing trio with hydration support. Studies in the International Journal of Cosmetic Science have shown oat-derived beta-glucan penetrates the stratum corneum and improves hydration and elasticity measurements. Notably, beta-glucan has also been used in post-laser recovery protocols, which aligns with this product's reputation as a post-procedure-friendly toner.
The real-world significance of these ingredients in this specific formulation is that they're present at meaningful positions on the INCI — MSM, beta-glucan, licorice and centella all appear before most of the functional filler ingredients — suggesting they're contributing more than a label-claim dose. That's what separates this from the many 'calming toners' built around a single headline ingredient surrounded by glycerin and water.
Dermatologists treating rosacea, perioral dermatitis, or post-procedure recovery frequently reach for fragrance-free hydrating toners like this one as gentle interim steps between cleanser and moisturizer. Many dermatologists stress that products combining centella, licorice, and beta-glucan in a fragrance-free base can serve as useful adjuncts alongside prescription treatments like metronidazole or azelaic acid — they don't replace the prescription but they can reduce the discomfort that often leads patients to abandon their regimen. Clinicians commonly recommend this specific product by name in sensitive-skin contexts because of its consistent formulation history, strong safety record, and the absence of fragrance — the single most common source of contact dermatitis in skincare consultations.
After cleansing, dispense three to four drops into clean palms, press evenly onto damp face and neck, and layer the next step while the skin is still slightly wet. Skip cotton pads — they absorb product without adding benefit. For post-procedure use, pat gently without rubbing. Safe to use twice daily, morning and night. Layer before essences, hydrating serums, niacinamide, or low-strength retinoids. If you're using azelaic acid or prescription topicals, apply this first as a soothing base, then follow with the active. Works fine under all moisturizer types including occlusive balms on very dry skin.
At around $22 for 180ml, the unscented Supple Preparation Toner matches the price of the original while removing the main obstacle to recommending it broadly. A bottle lasts three to four months for most users, putting the monthly cost near $6 — competitive with drugstore fragrance-free toners that have much simpler ingredient lists. For comparison, many Western sensitive-skin toners from dermatologist-developed brands cost more for formulations built almost entirely around glycerin and hyaluronic acid, without the MSM or centella layer. The lack of a larger size is the only value knock — if Klairs offered a 300ml bottle at even a 10% discount per milliliter, this would be an automatic repurchase for most heavy users. As it stands, the pricing is still honest and the formulation quality justifies it.
People with sensitive, reactive, rosacea-prone, or post-procedure skin who want a hydrating toner with real soothing actives and no fragrance. Also ideal for anyone who loves the scented version but wants to reduce cumulative sensitization, and pregnant users looking for a pregnancy-safe toner free of essential oils.
Skip if you're looking for an exfoliating, clarifying, or actives-heavy toner — this is purely a hydration and calming product. It is similarly a skip if you've already identified that you need specific treatment ingredients like salicylic acid, glycolic acid, or higher-strength vitamin C in your toner step.

All Year
Released a couple of years after the original Supple Preparation Toner, the Unscented version was Klairs' direct response to users who loved the formula but reacted to the essential oils. Instead of dismissing the feedback or launching a totally new product, the brand simply made a fragrance-free twin — which has since become the version most dermatology-adjacent recommenders point to for sensitive skin.
Dear, Klairs launched in 2010 under Wishtrend and built its reputation on minimalist, sensitive-skin-focused formulas. The unscented version of this toner was released specifically in response to customer feedback from users reacting to essential oils — an unusually transparent move that reinforced the brand's sensitive-skin positioning.
Unscented is always a marketing gimmick and brands just mask the scent
In this case, the INCI is verifiably shorter — the essential oils are genuinely absent, not covered by another fragrance. You can compare the two ingredient lists side by side and see the difference.
Fragrance-free toners don't work as well because they're 'watered down'
The active ingredient positions in this formula are identical to the scented version. What was removed adds irritation potential, not efficacy.
The only difference is the essential oil blend — lavender, ylang ylang, citrus and geranium oils — which is present in the scented version and removed here. Everything else, including MSM, beta-glucan, centella and the hyaluronic acid matrix, is identical in position and concentration.
It's one of the more frequently recommended hydrating toners for rosacea in online communities because it combines soothing actives (MSM, centella, licorice) with zero fragrance. That said, rosacea is individual — patch test on your jawline for a few days before full face use.
Yes — the unscented version is often suggested as a post-procedure hydrator because the formula contains nothing that would sting or trigger inflammation on compromised skin. Apply gently and follow with a barrier moisturizer.
Klairs didn't charge a premium for the sensitive-skin variant, which is why many reviewers default to recommending this one even when scent isn't a concern — you get the same formula minus the risk.
The pH sits around 5.0, which is compatible with layering before niacinamide, azelaic acid, or low-strength retinoids. It won't disturb the acidic environment most actives need to function.
Yes — the formula contains no retinoids, salicylic acid, or pregnancy-flagged actives. The absence of essential oils also makes it a safer choice for pregnant users who've been advised to avoid aromatic compounds.
