Long before sodium lauryl sulfate became the default way to strip a face clean, Korean women were grinding mung beans into a fine powder, mixing it with water, and using it to wash their skin. The practice worked — the saponins in mung beans create a gentle natural lather, while the starch absorbs oil without the scorched-earth approach of modern detergent-based cleansers. Beauty of Joseon took that centuries-old wisdom and built a contemporary cleanser around it, pairing mung bean extract with green plum water to create something that feels distinctly traditional in spirit but entirely modern in execution.
Green plum — maesil in Korean — is a fruit so fundamental to Korean culture that it appears in everything from cooking to medicine cabinets to, now, your bathroom sink. The plum water sits as the second ingredient in the formula, providing a naturally acidic base that helps the cleanser maintain a skin-friendly pH without relying heavily on synthetic pH adjusters. It also carries its own mild astringent and antioxidant properties, which means even the base solvent is doing something useful rather than just filling space.
The surfactant system is where this cleanser really earns its stripes. Cocamidopropyl hydroxysultaine and sodium cocoyl isethionate are among the gentlest cleansing agents available in cosmetic chemistry. Neither is a sulfate. Neither is an aggressive foam-builder. Together, they create a fine, almost reluctant lather — the kind that makes you wonder if anything is happening until you rinse and realize your skin feels thoroughly clean but completely comfortable. This is what modern cleansing science looks like when it prioritizes barrier preservation over dramatic foam.
The botanical supporting cast reads like a tour through a traditional Korean medicinal garden. Houttuynia cordata — known as eoseongcho in Korean herbal medicine — brings antibacterial and anti-inflammatory properties. Lotus flower extract contributes antioxidant and skin-soothing benefits. Rice extract maintains the hanbang thread that runs through all of Beauty of Joseon's products. And green tea extract delivers EGCG, one of the most researched antioxidants in skincare, which provides a brief burst of protective activity during the cleansing step.
Past the headline botanicals, the list trails off into a small orchard: blueberry, pomegranate, mangosteen peel, and butterfly pea flower extracts all make trace appearances near the bottom. In a rinse-off product these are decorative more than functional — a few seconds of contact time limits what any antioxidant can accomplish — but they're consistent with a brand that would rather garnish with fruit than with fragrance.
The texture is a translucent gel with a barely-there green tint — more fluid than you might expect, which can make dispensing a minor adventure if you're not prepared for the thin consistency. It spreads easily across wet skin and builds just enough foam to feel satisfying without crossing into the territory of aggressive surfactant action. The lather is more suggestion than statement.
Rinsing is clean and complete. There's no film, no residue, no sense that you need to wash your face again to get your cleanser off. And critically, there's no tightness. That post-wash feeling of comfortable, balanced skin is the single most important quality a cleanser can have, and this one nails it consistently.
Technique is simple and worth doing properly: thirty to sixty seconds of gentle massage on damp skin, then a lukewarm rinse — hot water undoes the barrier courtesy the surfactants just extended. In the evening it's the second act of a double cleanse, following an oil cleanser that has already dissolved makeup and sunscreen; in the morning it stands alone. The skin-type map is notable for having no exclusions at all — oily skin gets the best match, but dry and sensitive users are explicitly served rather than merely tolerated — and it's flagged pregnancy-safe. The one handling note: the gel runs thin, so start with less than you think you need and let the lather build.
What this cleanser doesn't do is equally important to acknowledge. It won't dissolve a full face of waterproof mascara and heavy foundation — that's a job for an oil cleanser in the first step of a double cleanse. It doesn't contain active exfoliants, so it's not going to chemically clear your pores. And it won't leave oily skin feeling mattified for hours. This is a cleanser that does one thing exceptionally well: it removes daily accumulation of oil, sweat, dust, and light product residue while leaving the skin barrier entirely intact.
The value proposition is particularly strong. At $10.40 for 100ml, it's already affordable, but the 200ml size at $14 is where the math gets genuinely compelling — double the product for a fraction more in price. For a cleanser you'll use twice daily, that kind of value adds up over months.
Four thousand reviews averaging 4.8 make this one of the highest-rated products in its category, and the consensus is nearly unanimous on the core promise: clean skin with zero tightness, day after day. The complaints are all quality-of-life rather than performance — the 100ml tube empties fast, heavy makeup defeats it alone, deeply oily skin occasionally wants more grip, and the runny gel escapes the careless. When a product's worst reviews concede that it works, the formula has done its job.
For anyone using retinoids, acids, or other active treatments, this cleanser deserves serious consideration. The gentlest surfactant system protects a barrier that your treatment products are already challenging, and the botanical extracts provide a layer of soothing that helps keep reactive skin from escalating. It's the kind of cleanser that dermatologists wish more people would use — one that supports the rest of your routine rather than undermining it.
The Green Plum Cleanser isn't flashy. It won't trend on social media for its dramatic foam or its Instagram-worthy application ritual. But it embodies a philosophy that K-beauty does better than almost any other tradition: the best products are the ones that do their job so quietly and competently that you forget they're there. Sometimes the most revolutionary thing a cleanser can do is simply not cause problems.
