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.
