Klairs Supple Preparation Unscented Toner Review (2026)

By Margaret Wojewoda, Founder & Editor Last updated June 29, 2026

Klairs Supple Preparation Unscented Toner is the classic fragrance-free hydrating “prep” toner — alcohol- and essential-oil-free, built on hyaluronic acid, beta-glucan, centella and panthenol to flood skin with comfortable hydration and prep it for everything that follows. It hydrates and soothes rather than exfoliating, so treat it as a barrier-friendly first layer, not a treatment.

Is it worth it? (the short answer)

For sensitive, dehydrated or layering-focused skin, yes — it’s one of the most reliable, widely-tolerated hydrating toners out there.

• Buy it if you want gentle, fragrance-free hydration, you “skin flood”/layer, or you’re oily/acne-prone but still need hydration.
• Skip it if you want an exfoliating toner, or you expect a toner to moisturise dry skin on its own.

What it is and how it works

This is the unscented, essential-oil-free version of Klairs’ famous prep toner, made for fragrance-sensitive skin. It’s a slightly thicker, hydration-forward formula: hyaluronic acid and beta-glucan (humectants that hold water), centella and panthenol (soothing, barrier-supporting), plus licorice, aloe and amino acids, all alcohol-free and pH-balanced. The job is “preparation” — soften and hydrate skin so the rest of your routine absorbs and spreads better.

What it is not: an exfoliating or active toner. There are no acids; it won’t treat acne or texture. It’s a comfort-and-prep step that needs a moisturizer after it.

Formulation and flags

What the internet really says

It’s one of the most-recommended “gentle hydrating toner” buys in skincare, praised as soothing, non-irritating and genuinely hydrating — reviewers with oily, dehydrated and acne-prone skin repeatedly note it hydrates without breakouts or a heavy feel.

The honest negatives:

• Not a treatment. People expecting it to “do” something active are underwhelmed — it preps and hydrates.
• Slightly thick. Fans of watery toners may find it a touch viscous (it’s intentional).
• Needs a moisturizer. It’s a layer, not a standalone for dry skin.

Our read: the safe, fragrance-free default hydrating toner — especially for sensitive or layering-focused routines. (User reports, not guarantees — your skin may differ.)

How to use it (and where it fits)

After cleansing, pat a layer (or several, for “skin flooding”) into damp skin before serums and moisturizer, morning and night. It pairs naturally with the rest of a fragrance-free Korean routine and under a barrier cream.

FAQ

Is Klairs Supple Preparation Unscented Toner worth it?

For sensitive, dehydrated or layering-focused skin, yes — it’s a gentle, fragrance-free, alcohol-free hydrating toner that’s widely tolerated, even by acne-prone skin. It preps and hydrates rather than exfoliating, so it’s a first layer, not a treatment.

What’s the difference between the unscented and original Klairs toner?

The unscented version drops the essential oils and added scent of the original Supple Preparation Facial Toner, making it the safer pick for fragrance-sensitive or very reactive skin. The hydrating base is otherwise similar.

Is Klairs Supple Preparation toner good for oily or acne-prone skin?

Yes — despite being hydrating it’s lightweight and widely reported not to cause comedones, so oily and acne-prone skin generally do well with it. It hydrates without a heavy or greasy feel.

Does it exfoliate?

No — there are no AHAs or BHAs. It’s a hydrating, soothing prep toner, so use your exfoliating acids separately if you need them.

How do you use Klairs Supple Preparation toner?

After cleansing, pat a layer (or several, for “skin flooding”) into damp skin before serums and moisturizer. Use morning and night; it layers well under the rest of a routine.
