The full review.
Brands often release unscented versions as a hedge, offering inferior performance in quieter packaging to address fragrance complaints. Klairs did the opposite. The Supple Preparation Unscented Toner uses the same MSM-beta-glucan-centella base as the original, removing only the lavender-citrus-geranium oil blend. No new preservative, extra filler, or dilution was added. Comparing the two INCI lists shows this is simply a better formula for those reactive to fragrance.
This distinction matters because MSM — dimethyl sulfone — is a potent soothing ingredient for reactive skin. The original Supple Preparation Toner undermined this by pairing soothing actives with irritating essential oils. Putting a rosacea sufferer near lavender oil is like giving a lactose-intolerant person a cheese board and claiming the salad is dairy-free. Klairs fixed this with the unscented version.
On skin, it behaves like the scented version without the sensory cues. It has no scent, no tingle, and no temperature change beyond the coolness of room-temperature liquid on damp skin. It absorbs in about thirty seconds, leaves a cushiony non-tacky finish, and works as a preparation step before essence or serum. This is the answer for people who want a Korean hydrating toner but cannot use fragrant versions.
The ingredients rely on a soothing trio with mechanistic backing. Dimethyl sulfone sits high on the INCI; it delivers organic sulfur that studies link to NF-κB pathway modulation, which calms inflammation. Centella asiatica provides madecassoside to support collagen synthesis and barrier repair. Licorice root adds glabridin, which has anti-inflammatory and mild tyrosinase-inhibiting activity—useful for post-inflammatory marks on reactive skin. Beta-glucan, sodium hyaluronate, panthenol, and amino acids handle hydration. Copper tripeptide-1 appears at the end of the list; the dose is a bonus, but its presence fits the formula’s construction.
The product earns its reputation through performance on sensitive skin. Users with mild rosacea, perioral dermatitis, or post-treatment redness report consistent calming within one to two weeks of twice-daily use. This matches the soothing actives. It also works well as a general hydrating toner for non-sensitive skin; the cushiony finish and ingredient profile make it a reasonable everyday choice. Given cumulative sensitization risks, choosing the unscented version is a defensible baseline regardless of current reactivity.
A few small issues exist. The packaging is nearly identical to the scented version—same frosted bottle, flat cap, and silhouette—so you might grab the wrong one if stored together. The pour cap is imprecise; pumps would control dispensing better, though you can tilt the bottle carefully instead of inverting it. While the 180ml bottle is large, no larger size exists for bulk buying.
Value is excellent. At around $22 for 180ml—the same price as the scented version in most markets—this is a cost-effective hydrating toner for sensitive skin. One bottle lasts three to four months with twice-daily use on face and neck, costing about six dollars a month. Many derm-adjacent voices recommend this for rosacea and barrier repair, making the value strong. Western fragrance-free hydrating toners often cost more for less interesting formulations.
The recommendation is simple. If you have fragrance sensitivity, rosacea, eczema, or react to K-beauty products, buy this instead of the scented version. If you have robust skin and like the original herbal scent, that version is fine—but there is no formulation penalty for choosing the unscented version as a default. It is the smarter pick and a sensitive-skin staple that holds up to scrutiny.

The science.
The Science
This toner uses a stack of ingredients with credible evidence. A 2015 review in Nutrients shows MSM (dimethyl sulfone) has anti-inflammatory activity through the NF-κB pathway, while smaller topical studies show erythema reduction in rosacea-like conditions. Centella asiatica has a large literature base; a 2012 review in the Indian Journal of Pharmaceutical Sciences summarized its triterpenoid-driven wound healing and barrier repair, and recent dermatology work validates madecassoside as a post-procedure calming agent.
Licorice root extract provides glabridin, a compound studied for anti-inflammatory effects and mild tyrosinase inhibition. Research in the International Journal of Molecular Sciences documents glabridin's relevance in conditions involving inflammation and post-inflammatory pigmentation. This makes it an appropriate addition to a sensitive-skin product that also addresses marks left after breakouts calm down.
Beta-glucan completes the soothing trio by supporting hydration. Studies in the International Journal of Cosmetic Science show oat-derived beta-glucan penetrates the stratum corneum and improves hydration and elasticity. Beta-glucan also works in post-laser recovery protocols, which fits this product's reputation as a post-procedure-friendly toner.
In this specific formulation, these ingredients appear at meaningful positions on the INCI. MSM, beta-glucan, licorice, and centella all appear before most functional filler ingredients, suggesting they provide more than a label-claim dose. This separates it from many 'calming toners' built around one headline ingredient surrounded by glycerin and water.
Dermatologist Perspective
Dermatologists treating rosacea, perioral dermatitis, or post-procedure recovery often use fragrance-free hydrating toners like this one as gentle steps between cleanser and moisturizer. Board-certified dermatologists note that products combining centella, licorice, and beta-glucan in a fragrance-free base work as useful adjuncts to prescription treatments like metronidazole or azelaic acid. They do not replace the prescription, but they reduce the discomfort that often leads patients to stop their regimen. Clinicians commonly recommend this specific product by name for sensitive skin because of its consistent formulation history, strong safety record, and the absence of fragrance—the most common source of contact dermatitis in skincare consultations.
Where it fits in your routine.
After cleansing, dispense three to four drops into clean palms. Press evenly onto a damp face and neck, then layer the next step while skin stays slightly wet. Skip cotton pads; they absorb product without benefit. For post-procedure use, pat gently instead of rubbing. Use twice daily, morning and night. Layer before essences, hydrating serums, niacinamide, or low-strength retinoids. If you use azelaic acid or prescription topicals, apply this first as a soothing base, then follow with the active. It works under all moisturizer types, including occlusive balms on very dry skin.
At about $22 for 180ml, the unscented Supple Preparation Toner matches the original price but removes the main barrier to broad recommendation. Most users finish a bottle in three to four months, making the monthly cost near $6 — similar to drugstore fragrance-free toners with simpler ingredient lists. Many Western sensitive-skin toners from dermatologist-developed brands cost more for formulas built mostly on glycerin and hyaluronic acid, lacking the MSM or centella layer. The lack of a larger size is the only value drawback — if Klairs offered a 300ml bottle with even a 10% discount per milliliter, most heavy users would repurchase it automatically. The pricing remains honest and the formulation quality justifies it.
This toner suits sensitive, reactive, rosacea-prone, or post-procedure skin needing hydration, soothing actives, and no fragrance. It also works for users who like the scented version but want to reduce cumulative sensitization, or pregnant users seeking a pregnancy-safe toner without essential oils.
Skip this if you want an exfoliating, clarifying, or actives-heavy toner; this product only hydrates and calms. Skip this too if you already need specific treatment ingredients like salicylic acid, glycolic acid, or higher-strength vitamin C in your toner step.

The backstory.
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.

FAQ.
Is this good for rosacea?
Online communities frequently recommend this hydrating toner for rosacea. It combines soothing actives (MSM, centella, licorice) and has zero fragrance. Rosacea affects everyone differently—patch test on your jawline for a few days before full face use.
Can I use this right after microneedling or a peel?
Yes — the unscented version works as a post-procedure hydrator because the formula lacks ingredients that sting or trigger inflammation on compromised skin. Apply gently and follow with a barrier moisturizer.
Why does it cost the same as the scented version?
Klairs charges no premium for the sensitive-skin variant. Many reviewers recommend this version even when scent isn't a concern because you get the same formula without the risk.
Does it have a pH suitable for layering with actives?
The pH is about 5.0. This works for layering before niacinamide, azelaic acid, or low-strength retinoids. It does not disturb the acidic environment most actives need.
Is it safe during pregnancy?
Yes — the formula lacks retinoids, salicylic acid, or pregnancy-flagged actives. It contains no essential oils, making it a safer choice for pregnant users advised to avoid aromatic compounds.
