Hyaluronic Acid Can Actually Dehydrate Your Skin (Here's When)
The internet's favorite hydrator has a counterintuitive dark side — in dry air, a humectant with nothing to seal it can pull water out of your skin instead of into it.
It takes Pyunkang Yul's cult astragalus Essence Toner — a 1%-root, water-light hydrator with a devoted following — and delivers it in a dual-textured pad, adding gentle physical wiping and a touch of willow-bark decongesting to the same soothing, ceramide-supported base. It's the hero toner reimagined as a convenient prep-exfoliate-hydrate step.
The pad form of Pyunkang Yul's cult astragalus Essence Toner: the same deeply hydrating, soothing base, now with gentle dual-textured wiping and a touch of willow-bark decongesting. Fragrance-free, ceramide-supported and around $19 for 70 pads, it's a convenient prep-exfoliate-hydrate step for most skin — though the bottled toner is the better value if you don't need the wiping.

Some skincare products earn a quiet, devoted following not by doing many things, but by doing one thing exceptionally well. Pyunkang Yul's Essence Toner is one of those: a minimalist, water-light hydrator built around a single hero ingredient, astragalus root, that K-beauty enthusiasts have championed for years as one of the best gentle hydration steps you can buy. This product is that beloved toner reimagined as a pre-soaked pad — and the interesting question is what the pad format adds, what it costs, and whether the trade is worth it for you.
Start with what stays the same, because it's the best part. The pads are soaked in essentially the brand's signature formula, anchored by Astragalus membranaceus root extract at a meaningful 1% (10,000 ppm), sitting high enough to replace most of the plain water rather than garnish the bottom of the list. Astragalus — milk vetch root — is a traditional Korean-medicine herb rich in antioxidant and skin-conditioning compounds, and it gives the formula a hydrating, soothing, faintly nourishing character that's the whole reason the original toner developed its cult. Hyaluronic acid and glycerin reinforce the hydration, drawing and holding water so skin reads plump and dewy. It's a genuinely good hydrating base, and the pads deliver it faithfully.
What the pad format adds is twofold. First, gentle physical action: each dual-textured pad — one side smooth, one lightly textured — sweeps away leftover cleanser residue and loose dead cells while depositing the essence, a small mechanical exfoliation the liquid simply can't provide. Second, the formula folds in a few clarifying-and-soothing extras: willow bark for a mild, salicin-based pore-decongesting nudge, houttuynia (heartleaf) for a purifying, calming note suited to congestion-prone skin, and centella for soothing. Crucially, it also includes ceramide NP, a barrier-replenishing lipid that offsets any disruption from the wiping — a thoughtful touch that keeps this exfoliation-adjacent step gentle enough for daily, sensitive-skin use. The result is a single step that preps, lightly exfoliates and hydrates all at once.
In practice it's a pleasure and genuinely low-effort. After cleansing, you sweep a pad over the face and it leaves skin soft, damp and freshly prepped, ready for serums and moisturizer. There's no sting, the exfoliation is subtle rather than scrubby, and the fragrance-free, essential-oil-free formula keeps it friendly to reactive skin. For people who like the ritual and convenience of a pad — or who want that built-in residue-removal and gentle smoothing — it's an easy, pleasant addition to a routine, and it works morning or night.
Its limitations are mostly about value and format rather than performance. Pads inherently use more material per use than a bottle, which makes them less economical and less eco-friendly — and the bottled Essence Toner gives you the same hydrating astragalus base for a lower cost per use and far less waste. So if you don't specifically want the wiping action, the liquid is the smarter buy. The exfoliation, while nice, is mild — this won't tackle stubborn texture or congestion on its own. It's not fungal-acne safe, as the lecithin and triglyceride components may not be malassezia-friendly. And while 70 pads sounds generous, daily-or-twice-daily use works through them in a couple of months.
On value, around nineteen dollars for 70 pads is reasonable rather than remarkable — fair for the convenience and the quality of the underlying formula, but a step down in cost-efficiency from the bottle. The people who'll love it are anyone who wants a convenient, multitasking hydration-and-prep step and likes the gentle smoothing a pad provides, especially normal, combination, dry and sensitive skin types drawn to Pyunkang Yul's minimalist, soothing approach. The ones who should stick with the bottled toner are cost- and sustainability-focused shoppers who just want the hydration. Either way, the astragalus base underneath is the same quietly excellent hydrator that built the brand's reputation — and getting it in pad form, with gentle exfoliation and ceramide support folded in, is a genuinely useful option for the routines that suit it. A final practical thought on whether pads suit your particular routine. The convenience is real — for travel, for mornings when you're rushing, or for anyone who finds the ritual of sweeping a pad more satisfying than splashing a liquid, the format genuinely earns its place. But it's worth being honest with yourself about waste and cost: if you're the kind of person who'll happily use the bottled toner every day without the pad's prompt, you'll save money and packaging by doing so. Where the pads shine is for people who otherwise skip toner entirely, or who want that small extra step of physical residue-removal after cleansing. Matched to the right habit, they're a pleasant, effective addition; bought out of pure novelty, they may sit half-used in a drawer. Know which kind of user you are, and the value question answers itself.
The hero actives that drive this product's performance.
| Ingredient | Function | Evidence |
|---|---|---|
| Astragalus Membranaceus Root Extract (10,000 ppm) (1%) | The brand's signature active and the soul of its hero toner: a 1% dose of astragalus (milk vetch) root, a traditional Korean-medicine herb rich in antioxidant and skin-conditioning compounds. Replacing most of the plain water in the original toner, it gives the pads a hydrating, soothing, antioxidant base that defines the whole product rather than acting as a filler extract. | Not yet assessed |
| Sodium Hyaluronate + Glycerin | The hydration core: hyaluronic acid and glycerin draw and hold water to plump and soften, turning each pad into a quick hydration-and-prep step. They keep the gentle physical wiping from feeling drying, so skin reads dewy rather than stripped after use. | Established mechanism for Dehydration · established mechanism |
| Willow Bark + Houttuynia + Centella | A clarifying-and-soothing trio: willow bark adds a mild salicin-based decongesting note, houttuynia (heartleaf) purifies and calms congestion-prone skin, and centella soothes. Together with the pad's wiping action they gently lift dead cells and debris while keeping the formula calming rather than aggressive. | Not yet assessed |
| Ceramide NP | A barrier-replenishing lipid that offsets any disruption from wiping, helping the pads support rather than compromise the skin barrier — a thoughtful inclusion that keeps an exfoliating-adjacent step gentle enough for daily, sensitive-skin use. | Established mechanism for Dryness · established mechanism |

After cleansing, gently sweep one pad over the face to hydrate, prep and lightly wipe away residue, then follow with serums and moisturizer while skin is damp. Use the textured side for a touch more exfoliation or the smooth side for pure hydration. Avoid pairing with strong leave-on acids on the same wipe to keep it gentle.
Immediate: skin feels hydrated, soft and freshly prepped. Short-term (1-2 weeks): smoother texture and a brighter, more even surface with daily wiping. Full benefit (4-8 weeks): consistently soft, well-hydrated and calm skin, with the gentle exfoliation keeping texture refined over time.
The pads' core benefit is hydration, well supported by the humectant base. Sodium hyaluronate and glycerin are benchmark humectants that bind water in the stratum corneum to plump and soften skin, and the high-placed astragalus (Astragalus membranaceus) root extract is the brand's signature: astragalus contains polysaccharides, flavonoids and saponins with antioxidant and skin-conditioning evidence, though robust clinical data for topical cosmetic use is limited, placing it in the promising category. The added actives have reasonable support: willow bark (Salix alba) provides salicin, a mild natural precursor toward salicylic acid with gentle keratolytic and anti-inflammatory effects, useful for light decongesting; houttuynia cordata and centella asiatica have anti-inflammatory and soothing evidence; and ceramide NP is part of the well-validated lipid-replacement approach to barrier support, sensibly included to offset any disruption from physical wiping. The mechanical exfoliation from the textured pad is gentle and surface-level. The honest synthesis: this product's hydration and soothing claims rest on solid humectant and barrier science plus a promising signature botanical, while its exfoliation is mild by design — a multitasking prep step rather than a potent resurfacing treatment.
Hydrating toner pads occupy a practical niche in clinical terms: they combine light physical cleansing-residue removal with humectant delivery, which can be a convenient prep step, though dermatologists generally note that physical exfoliation should be gentle and infrequent enough to avoid barrier irritation. This formulation's inclusion of ceramide, centella and a fragrance-free base reflects a sensible, barrier-conscious approach that limits that risk, and the willow bark offers only a mild clarifying effect rather than aggressive exfoliation. Humectants like hyaluronic acid and glycerin are broadly endorsed for hydration. Standard guidance would frame a product like this as a pleasant, low-risk hydration-and-prep step rather than a treatment, suitable for daily use on most skin types including sensitive, with the caveat that those prone to fungal acne should review the ingredient list and that pads are used in addition to, not as a replacement for, core actives and sun protection.
After cleansing, take one pad and gently sweep it across the face and neck, using the textured side for a little extra exfoliation and residue removal or the smooth side for pure hydration. Don't scrub — light passes are enough. While skin is still damp from the essence, follow with your serums and moisturizer to lock in hydration. Use it morning and/or night; for sensitive skin, once daily is plenty. In the morning, finish with sunscreen. Avoid combining it on the same pass with strong leave-on acids to keep the step gentle.
At around nineteen dollars for 70 pads, the value is reasonable but not exceptional, and it hinges on whether you want the pad format. You're paying a convenience premium over the bottled Essence Toner, which delivers the same hydrating astragalus base at a lower cost per use and with far less waste. What the pads add — gentle exfoliation, residue removal and a tidy one-step ritual — is worth the difference if you'll use those features, but redundant if you just want hydration. Used once daily, the tub lasts a couple of months. For fans of the brand's hero toner who specifically want a multitasking wipe, it's a fair buy; for the cost- and sustainability-minded, the liquid version is the better-value way to get the same beloved formula.
This suits anyone wanting a convenient, multitasking hydration-and-prep step with gentle built-in exfoliation — especially normal, combination, dry and sensitive skin drawn to Pyunkang Yul's soothing, minimalist approach. It's a natural pick for fans of the brand's cult Essence Toner who'd like that same astragalus hydration in a quick, wipeable pad format.
Cost- and sustainability-focused shoppers who just want the hydration should choose the bottled Essence Toner, which delivers the same base more economically and with less waste. Those needing strong exfoliation for stubborn texture should look to a dedicated chemical exfoliant, and anyone rigorously managing fungal acne should check the INCI first.

Pyunkang Yul's Essence Toner became a K-beauty cult object for doing one thing exceptionally — deep, gentle hydration from astragalus root in a minimalist formula. This pad version answers fans who wanted that same essence in a quick, wipeable format, folding in light exfoliation and clarifying botanicals for a more multitasking daily step.
Pyunkang Yul grew out of South Korea's Pyunkang Korean Medicine Hospital and launched in 2010, earning a cult following for minimalist, low-irritant formulas — its astragalus-based Essence Toner is the brand's signature hero. This is the pre-soaked pad version of that famous toner, adding gentle physical wiping to the same hydrating base.
Toner pads are just pre-soaked wipes that work the same as splashing on a liquid toner.
The pad adds gentle physical exfoliation and residue removal the liquid can't, lifting dead cells and leftover cleanser while depositing the essence. It's a genuinely different step — prep, light exfoliate and hydrate in one — though it does use more material per use than a bottle.
They share the same hydrating astragalus-based formula, but the pad adds gentle physical wiping that lifts dead cells and leftover residue while depositing the essence, plus a touch of willow bark and ceramide. The liquid is more economical and eco-friendly; the pads are a convenient prep-exfoliate-hydrate step in one.
Lightly. The dual-textured pad provides gentle physical exfoliation and willow bark adds a mild salicin-based decongesting effect, but it's subtle, not a strong chemical or scrub exfoliation. That makes it safe for daily use, including on sensitive skin, without over-exfoliating.
Yes — it's fragrance-free and essential-oil-free, built on a soothing astragalus, centella and ceramide base, with gentle wiping rather than harsh scrubbing. Most sensitive skin tolerates it well as a calming hydration-and-prep step.
After cleansing, sweep one pad gently over the face to hydrate and lift away residue, then follow with serums and moisturizer while skin is still damp. Use the textured side for a little more exfoliation or the smooth side for pure hydration, morning and/or night.
It depends on what you value. If you want convenience and a built-in gentle exfoliation-and-residue-removal step, the pads are worth it. If you prioritize cost-per-use and sustainability, the bottled Essence Toner delivers the same hydrating astragalus base for less waste.
Not strictly — the formula contains components like lecithin and caprylic/capric triglyceride that may not be malassezia-safe. Those rigorously managing fungal acne should review the full INCI against their triggers.
