It is a cream-textured foaming cleanser built on the syndet trio of sodium cocoyl isethionate, lauryl betaine and a taurate at a declared pH of 5.5, with ceramide NP, cholesterol and stearic acid at the end of the list and the line's black soybean and panthenol for identity, fragrance-free and sulfate-free. Against the gel cleansers that dominate Korean skincare it is the lotion-like, dry-skin option, and against the brand's own Soybean Nourishing Cleanser it drops the sulfonate and the adzuki grains.
A fragrance-free, sulfate-free cream-foam cleanser at a declared pH of 5.5, built on the syndet trio of isethionate, lauryl betaine and a taurate, with a trace of ceramide, cholesterol and stearic acid at the end of the list; it foams densely, rinses clean and leaves dry, sensitive and retinoid-stressed skin soft rather than tight. The soybean and panthenol are the line's name rather than a function in a thirty-second wash, it is new and unreviewed, and at $17 it is the sort of quiet, well-made cleanser that does its job and asks for no attention.
Two months on the US site, no reviews and no published testing leave the cleanser without a record of its own. The assessment rests on a twenty-four-ingredient syndet formula at a declared pH, whose behaviour is well characterised, and on the brand's consistent record with gentle cleansers rather than on any user outcome.

The studies behind the evidence row
Excellent at the jobDoes what a cleanser is for, on every measure we can take from the label: pH match to skin, surfactant mildness.
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
Cleansers are the category where the ingredient list tells almost the whole story, and Round Lab's Soybean Panthenol Cleanser has a list of twenty-four that reads like a textbook example of a mild syndet cream. Sodium cocoyl isethionate second, lauryl betaine fourth, sodium methyl cocoyl taurate seventh: an anionic isethionate, an amphoteric betaine and a taurate, the three-surfactant combination that lowers the free-monomer fraction that irritates and produces a dense, creamy foam without a sulfate, at a pH the brand declares as 5.5, which is where skin sits. Glycerin is third, and glyceryl stearate with stearyl alcohol turn the whole thing from a gel into a lotion-textured cream that feels cushioned on the face. There is no fragrance, no alcohol, no essential oil, no dye, and the last three ingredients are ceramide NP, cholesterol and stearic acid, the barrier trio, placed where a rinse-off can deposit a trace before the water takes the rest. It is the same logic as a dermatologist's syndet bar, in a tube, with a Korean brand's finish, and it is the logic that makes a foaming cleanser safe for skin that other foaming cleansers strip.
On the face it behaves exactly as that list predicts. A pea-sized amount whips into more foam than a cream usually gives, fine-bubbled and dense; it glides rather than drags, removes sebum, sweat and everyday sunscreen, and rinses completely, leaving the skin soft, calm and, the important part, not tight. Dry and sensitive skin notices the absence of squeak in the first wash, which is the moment most people decide whether a cleanser stays, and retinoid or acid users get the bland, non-stripping cleanse those routines need. Heavy makeup and waterproof sunscreen need an oil first, as with every water-based wash however gentle, and the brand sells this bundled with its cleansing oil for exactly that. The soybean, tenth, and the panthenol, fifteenth, undeclared here where the line's toner declares them, are the identity of the range and cannot do much in thirty seconds of contact beyond a faint conditioning note; a buyer who chooses this for the B5 is choosing it for the wrong reason and will still be pleased, because the surfactants are right. That is the pattern across this line, a good formula carrying a name that credits the wrong ingredient, and it is a harmless pattern in a cleanser.
The record is empty, the cleanser having reached the US site in July 2025 with no reviews and no published testing, and it matters less than usual: a syndet cream at pH 5.5 with these three surfactants is a well-characterised thing, and the brand's older Soybean Nourishing Cleanser, which uses a rougher isethionate-sulfonate base with adzuki grains, shows the direction of travel, this being the softer, grain-free, dry-skin sibling rather than a rename; the two share a word and a bean and little else. The two sit side by side in the range, and the Panthenol version is the one to reach for when the skin is tight or the routine is full of actives.
The limits are honest and small. It cleans and does nothing else; the ceramides mostly rinse away, the soybean is a word, and no cleanser repairs a barrier, which is the job of the toner and cream that follow and the reason the line sells all three together. The triglyceride, cholesterol and fatty esters near the end make it marginally less than ideal for fungal-acne-prone skin, though in a rinse-off the concern is slight and the brand's Dokdo cleansers exist for that face. And it is unglamorous, which is the point; a cleanser that draws attention to itself is usually doing so by stinging.
On price, $17 for 150 millilitres lasts three to four months at a pea-sized amount twice a day, in line with the brand's other cleansers and fair for a fragrance-free, pH-declared syndet cream from an established name; it is neither the cheapest gentle cleanser on the market nor overpriced for its formulation, and the double-cleansing bundle with the cleansing oil is the thriftier way to buy it for anyone taking the whole line.
So the recommendation is easy. Dry, sensitive, normal or combination skin that wants a fragrance-free cream wash that foams properly and leaves nothing tight, especially under a retinoid or in winter, will find this one of the better-built cleansers in K-beauty and will forget it is there, which is the highest compliment a cleanser earns. It will not change anyone's skin, and it will not damage anyone's either, and the second of those is rarer than it should be. Oily skin can use it but may prefer a gel that leaves even less behind; fungal-acne-prone skin has the Dokdo range; and anyone reading the name for the panthenol should read the second, fourth and seventh ingredients instead.
The hero actives that drive this product's performance.
| Ingredient | Function | Evidence |
|---|---|---|
| Sodium Cocoyl Isethionate with Lauryl Betaine and Sodium Methyl Cocoyl Taurate | The cleansing system, and the whole point: isethionate second, a betaine fourth and a taurate seventh, the three mild surfactants that make a dense, creamy foam at a declared pH of 5.5 and rinse without the tight, squeaky after-feel of a sulfate; it is the same 'syndet' logic as a dermatologist's bar, in a cream. | Not yet assessed |
| Glycerin with Glyceryl Stearate and Stearyl Alcohol | Glycerin third and two fatty structurants after it, which turn the surfactants into a cream rather than a gel and leave a faint softness after rinsing; the reason the cleanser feels like a lotion in the hand and cushions dry skin during the wash. | Established mechanism for Dryness · established mechanism |
| Ceramide NP, Cholesterol and Stearic Acid | The barrier trio in the last three positions of a rinse-off, where they can deposit a trace of lipid on the skin before the water carries most of it away; they make the cleanser the least stripping in the brand's range and justify the barrier language only modestly. | Established mechanism for Dryness · established mechanism |
| Fermented Black Soybean Extract with Panthenol | The line's two named ingredients, the Jeongseon black soybean tenth and panthenol fifteenth, at undeclared levels in a product on the skin for thirty seconds; they are the identity, and neither can do much in a wash beyond a faint conditioning note. | Not yet assessed |

cleanser
AM & PM
Use it as the morning wash or the second step of an evening double cleanse after the line's cleansing oil has taken off sunscreen and makeup; a pea-sized amount lathered in wet hands is enough, and it rinses clean. It leaves skin calm enough to go straight to a toner and any acid or retinoid, and on dry skin it is the cleanser to pair with those actives.
Immediate: a dense, creamy foam that rinses to soft, non-tight skin with no squeak. Short-term (1-2 weeks): less post-wash tightness and redness than a stronger foaming cleanser. Long-term: a barrier left alone twice a day; the ceramides and soybean add a faint conditioning note and treat nothing.
The cleanser is a synthetic-detergent cream formulated at skin-compatible pH. Sodium cocoyl isethionate, an anionic acyl isethionate, is among the mildest primary surfactants in patch and in-use testing, with low protein denaturation and barrier-lipid extraction relative to sulfates; lauryl betaine, an amphoteric surfactant, and sodium methyl cocoyl taurate, an acyl taurate, combine with it to reduce the critical micelle concentration and the free-monomer fraction responsible for irritation, a standard mild-surfactant strategy that permits dense foam without harshness. The declared pH of 5.5 matches the stratum corneum's acid mantle, and low-pH cleansing is associated in controlled studies with less post-wash barrier disruption and less transient alkalinisation than alkaline soaps. Glycerin at the third position provides humectancy during the wash; glyceryl stearate and stearyl alcohol structure the cream and leave a faint residual emolliency, with cetearyl olivate, sorbitan olivate and polyglyceryl-10 stearate as gentle co-emulsifiers.
The barrier and botanical components are present at low levels in a rinse-off. Ceramide NP, cholesterol and stearic acid occupy the final three positions; rinse-off deposition of lipids is limited and dose-dependent, so their contribution is modest, and the barrier-lipid benefit documented for ceramide-cholesterol-fatty-acid mixtures applies to leave-on formulations. Glycine max (soybean) seed extract supplies isoflavones and amino acids with antioxidant activity that cannot act meaningfully in thirty seconds of contact; panthenol, at an undeclared level, has established leave-on evidence for barrier recovery that likewise does not transfer to a wash. Caprylic/capric triglyceride, hydrogenated lecithin and the fatty esters add slip and are Malassezia substrates at low levels. Sodium polyacrylate thickens, citric acid sets the pH, sodium phytate chelates, and preservation uses 1,2-hexanediol and ethylhexylglycerin with dipropylene and butylene glycols. The formula contains no fragrance, sulfates, alcohol, essential oils or dyes, and its irritation potential is expected to be among the lowest in the foaming-cleanser category; soy extract is a consideration for soy-allergic individuals. It is vegan and suitable in pregnancy. No study of the product exists.
For daily cleansing, dermatologists recommend a mild synthetic-detergent cleanser at a pH close to the skin's, without fragrance, for patients with dry, sensitive or atopic skin and for anyone on retinoids, benzoyl peroxide or acids, since harsh or alkaline cleansing compounds the barrier disruption those treatments cause; a cream-foam syndet on isethionate, betaine and taurate at a declared pH of 5.5 meets that standard as well as any cleanser sold, and clinicians would expect it to be tolerated by nearly all skin. They would regard the ceramides, soybean and panthenol as marketing in a rinse-off, note that barrier repair comes from what is applied afterwards, and advise patients wearing heavy or waterproof makeup to precede it with an oil cleanser. Patients with Malassezia folliculitis might be pointed to an ester-free gel, though the risk from a rinse-off at these levels is small.
Wet the face with lukewarm water, squeeze a pea-sized amount into wet palms and rub briefly to build a dense foam, then massage it over the face for twenty to thirty seconds, avoiding the eyes, and rinse thoroughly. In the morning it is the only cleanse needed; in the evening, use it after an oil or balm cleanser has dissolved sunscreen and makeup, or alone on a no-makeup day. Pat dry and apply toner while the skin is still slightly damp. Twice daily suits all skin types, and there is nothing in it to patch test for beyond ordinary caution; soy-allergic users should note the extract.
Seventeen dollars for 150 ml is about $3.35 an ounce, in line with the brand's other cleansers and fair for a fragrance-free syndet cream with a declared pH from an established name; a tube lasts three to four months at a pea-sized amount twice a day, so the monthly cost is low. The money buys the right surfactant system for dry and sensitive skin, a cushioned cream texture and the Soybean Panthenol branding; it does not buy any barrier repair beyond what a non-stripping wash allows, and the double-cleansing bundle with the line's cleansing oil is the cheaper way to own it. Good, unexciting value.
Dry, sensitive, normal or combination skin that wants a fragrance-free, sulfate-free cream cleanser that foams properly and leaves no tightness, particularly anyone on a retinoid or acid routine or cleansing through a dry winter. It suits Soybean Panthenol line users and people who found the older Soybean Nourishing Cleanser's grains too much.
Anyone buying it for the panthenol or ceramides will find them nominal in a rinse-off, and fungal-acne-prone skin may prefer the ester-free Dokdo cleansers. Heavy or waterproof makeup wearers need an oil cleanser first, and very oily skin may prefer a lighter gel.

The first wash is quietly reassuring: a lotion-like cream that foams more than expected, feels cushioned rather than slippery, and rinses to a face that is clean, soft and not tight. Dry and sensitive skin notices the absence of squeak at once. There is no scent and nothing to adjust to; the only decision is how little to use, since a pea-sized amount is plenty.

All Year
Round Lab's Soybean Panthenol line launched in 2024 as a barrier-repair range beside the older Soybean Nourishing products, and the cleanser followed in July 2025 as its water-based wash, formulated at pH 5.5 on mild surfactants with a barrier-lipid trio, and sold in a double-cleansing bundle with the line's cleansing oil and sheet mask.
Founded in 2017, ROUND LAB is one of the K-beauty brands with genuine US retail footing, sold at Sephora and Amazon and best known for gentle, unscented cleansers and toners. The Soybean Panthenol Cleanser, added in July 2025 to the brand's barrier-repair sub-line, is a pH 5.5 cream-foam wash distinct from the older Soybean Nourishing Cleanser; it has no US reviews yet and the brand publishes no testing.
Ceramides in a cleanser repair the skin barrier
Ceramide NP, cholesterol and stearic acid sit in the last three positions of a rinse-off that is on the skin for thirty seconds; a trace may deposit, most rinses away. Their real value is signalling a formula that avoids stripping; barrier repair comes from the leave-on toner and cream that follow.
A cream cleanser cannot foam or clean properly
This one is a syndet cream: isethionate, a betaine and a taurate whip into a dense foam that removes sebum, sweat and light sunscreen thoroughly, while the glyceryl stearate and stearyl alcohol give the lotion texture. Heavy makeup and waterproof sunscreen still need an oil cleanser first, as with any water-based wash.
Different formulas from two sub-lines. The Nourishing Cleanser uses an isethionate-glycinate base with a sulfonate and adzuki bean grains for a gentle scrub; the Panthenol Cleanser is a cream-foam syndet on isethionate, lauryl betaine and a taurate at pH 5.5, with ceramide NP, cholesterol and stearic acid and no grains. The Panthenol version is the softer, dry-skin one; the Nourishing is the lightly exfoliating one.
Yes, it is built for it: fragrance-free, sulfate-free, alcohol-free, a declared pH of 5.5, a lotion-like cream that foams without squeak and a trace of barrier lipids. It leaves dry, sensitive and retinoid-stressed skin soft rather than tight, and there is nothing in the twenty-four ingredients that commonly sensitises beyond the soy extract.
Light makeup and everyday sunscreen, yes; waterproof mascara and heavy foundation need an oil or balm first. The brand sells it as the second step after its Soybean Panthenol Cleansing Oil and as a standalone morning wash.
Very little directly. Ceramide NP, cholesterol and stearic acid are the last three ingredients in a rinse-off, so most goes down the drain; their presence mainly signals a formula designed not to strip. The barrier work is done by the leave-on toner and cream in the same line.
Acne-prone skin, yes; it is fragrance-free, non-stripping and rinses clean. Fungal-acne-prone skin should note the caprylic/capric triglyceride, cholesterol and fatty esters near the end of the list, which are Malassezia substrates; in a rinse-off the risk is small but the brand's Dokdo cleansers avoid them altogether.
It is fairly priced for a fragrance-free, pH-5.5 syndet cream cleanser from an established brand, lasting three to four months at a pea-sized amount twice a day, and in line with the brand's other cleansers. It is unglamorous and new, and the soybean and panthenol are identity rather than function in a wash, but the surfactant system is the right one for dry faces.
