Full Review
The first ingredient on the Beplain Greenful Cleansing Foam is glycerin. The second is mung bean extract at 33% concentration. Stop and consider how unusual that is. On the vast majority of foaming cleansers — including many premium ones — glycerin shows up somewhere in the bottom third of the INCI as a token humectant, and the hero botanical sits at well under one percent as a marketing prop. This cleanser inverts both conventions. Glycerin sits at position one because the formulator wanted to make sure the cleanser would not leave skin tight after rinsing. Mung bean sits at 33% because the formulator wanted the antioxidant and soothing fraction of the plant to actually do something during the brief contact window of cleansing. Those two decisions are the reason this product behaves differently from the typical foaming face wash, and they are the reason it has earned its quiet cult following in K-beauty enthusiast circles.
The surfactant system is built on sodium cocoyl glycinate and sodium lauroyl glutamate, two amino-acid-derived surfactants that have become the gentle gold standard for modern foaming cleansers. Both are significantly milder than traditional sulfates like SLS, both produce a softer and more cushioned foam profile, and both have lower irritation potential in patch testing. Together they create the dense, whipped cream-foam texture that distinguishes this cleanser from a thin, airy lather. The foam is the kind that feels like something rather than nothing — substantial enough to massage, soft enough to rinse cleanly, mild enough to use twice a day without stripping. There is no fragrance and no alcohol. The faint herbal note that comes through is from the mung bean and the supporting botanical extracts.
And what a roster of supporting botanicals it is. Beyond the headline mung bean, the formula includes Centella asiatica, Roman chamomile, neem leaf and flower, cocoa seed, ivy gourd, eggplant, aloe flower, fig fruit, holy basil, turmeric root, and corallina algae. This is not a brief flirtation with botanicals — this is a kitchen-sink approach in the genuine sense, with the brand layering small amounts of each into a complementary calming and antioxidant matrix. Critics could fairly point out that the individual contribution of any one of these extracts at the bottom of the INCI is modest, and that is true. The honest framing is that the heavy lifting is done by the mung bean and the surfactant system, while the rest of the botanicals add a soft cumulative layer of soothing support. Allantoin and panthenol round out the calming roster.
The most pleasant surprise in the formula is the ceramide NP near the bottom of the INCI. A ceramide in a foaming cleanser is unusual — most brands save their ceramide budget for creams and serums where the leave-on contact time justifies the inclusion. Beplain has a habit of tucking ceramides into products where competitors would skip them, and the small barrier-supporting boost is consistent with the brand's overall philosophy of using each product as an opportunity to do a little extra rather than a little less. The pH is in the skin-comfortable range as the product name suggests, which means it will not disrupt the barrier in either direction during the few seconds it spends on the face.
The practical limitations are honest and minor. The cleanser will not remove heavy or waterproof makeup on its own — it is not formulated to dissolve film-forming long-wear products, and trying to use it as a one-step makeup remover on a full face is asking the wrong question. As a second cleanse following an oil cleanser, it is excellent. As a single cleanse on bare or lightly tinted-moisturizer skin, it is excellent. As a daily morning cleanser, it is excellent. The 80ml tube is the most common size in international K-beauty distribution, and at sixteen dollars per tube the price is reasonable rather than aggressive. The 160ml size offers slightly better per-milliliter value for committed users. Beplain's US distribution has historically been patchier than the bigger K-beauty exports, but the cleanser is now widely available through international K-beauty retailers and some US Olive Young locations.
Value is where the product lands in genuinely strong territory. Sixteen dollars for an 80ml tube of a formulation this thoughtful would be considered a steal coming from a Western dermatologist-marketed brand at twenty-five to thirty dollars. The K-beauty market in general delivers better formulation value than its Western counterparts at this price point, and Beplain specifically punches above its weight. Combined with the brand's Chamomile Toner and Cicaful Ampoule, the three-product cleanser-toner-ampoule routine sits well under sixty dollars total — a genuinely impressive value position for a sensitive-skin K-beauty routine.

| Ingredient | Function | Evidence |
|---|---|---|
| Mung Bean Extract (Vigna Radiata Seed Extract) (33%) | Sits at position two on the INCI at a labeled 33% concentration — extraordinarily high for a cleanser. Mung bean carries flavonoids and polyphenols including caffeic acid, contributing antioxidant and mild soothing benefits during the brief contact time of cleansing. The position is what makes this a meaningfully different cleanser from the typical mung-bean-flavored marketing exercise. | emerging |
| Glycerin | Sits at position one — extremely unusual for a cleanser, where glycerin is typically buried lower. This position is the reason the foam does not leave skin tight after rinsing; the residual glycerin pulls water back into the surface as the surfactants lift away oil. | well-established |
| Sodium Cocoyl Glycinate & Sodium Lauroyl Glutamate | Two amino-acid-derived surfactants that handle the actual cleansing. Both are gentler alternatives to traditional sulfates, with lower irritation potential and a softer foam profile. Together they create the cushioned cream-foam texture this cleanser is known for. | well-established |
| Ceramide NP | Sits low on the INCI but contributes a small barrier-supporting boost during cleansing — unusual for a foam cleanser and consistent with the brand's habit of tucking ceramides into products where most competitors would skip them. | well-established |

Evidence
Science
The Science
The cleansing science here is built on amino-acid surfactants — sodium cocoyl glycinate and sodium lauroyl glutamate — that have accumulated peer-reviewed evidence supporting their use as gentler alternatives to traditional sulfates. Both compounds have lower critical micelle concentrations and reduced affinity for skin proteins compared to anionic sulfates like SLS, which translates to lower disruption of the stratum corneum lipid bilayer during cleansing. Studies on amino-acid-surfactant cleansers have consistently shown reduced post-wash transepidermal water loss and improved sensory comfort metrics compared to identical formulas built on harsher surfactants.
The position of glycerin at INCI slot one is the most clinically meaningful design choice in this cleanser. Glycerin in a rinse-off product is doing one specific job: leaving a measurable residual humectant load on the skin surface after rinsing, which prevents the post-wash tightness that defines stripped formulations. Studies on glycerin-containing cleansers have shown improved after-wash hydration metrics compared to identical formulas without glycerin, and the position-one slot in this product suggests a high enough concentration to deliver meaningful benefit.
Mung bean extract (Vigna radiata seed extract) is the most novel ingredient in the formula. Mung bean carries flavonoids and polyphenols, including caffeic acid, vitexin, and isovitexin, that have demonstrated antioxidant and mild anti-inflammatory activity in laboratory studies. Clinical work on topical mung bean preparations is more limited than for the better-studied actives in the formula, but at 33% concentration the contribution during the brief cleansing window is more substantial than in fractional-percentage formulations. Centella asiatica, Roman chamomile, and the smaller botanical extracts further down the INCI add complementary calming and antioxidant layers, with the same caveat that individual contributions at low concentrations are modest. The inclusion of ceramide NP at the bottom of the formula is unusual for a foaming cleanser and provides a small barrier-supporting boost consistent with the brand's overall philosophy.
Dermatologist Perspective
Dermatologists generally view amino-acid-surfactant cleansers with humectant-forward formulations as appropriate first-line recommendations for patients with sensitive, acne-prone, or barrier-compromised skin. The combination of sodium cocoyl glycinate, sodium lauroyl glutamate, position-one glycerin, and a fragrance-free base in this product aligns with standard dermatologic guidance for daily cleansing in reactive or inflammatory skin conditions. Korean indie brand cleansers receive less direct dermatologist endorsement than legacy clinical brands, but the formulation principles in this product are consistent with what board-certified dermatologists recommend for daily use in sensitive-skin patients. The most common clinical caveats are around makeup removal expectations and the need for a second-cleanse oil step on heavy makeup days.
Guidance
Usage Guide
How to Use
Squeeze a pea-sized amount onto wet hands, work into a soft, dense lather between the palms, and massage onto damp skin in circular motions for 30-60 seconds. Rinse thoroughly with lukewarm water — hot water will undermine the gentleness of the formula. Pat dry with a clean towel and follow immediately with the rest of your routine. For full makeup days, use an oil cleanser or balm first and follow with this foam as the second cleanse. Suitable for morning and evening use without over-stripping.
Value Assessment
At $16 for 80ml the price is genuinely competitive — among the strongest formulation-to-price ratios in the K-beauty foaming cleanser category. The 160ml size offers slightly better per-milliliter value for committed users. Per month with twice-daily use, the 80ml runs roughly $5-8, which is comparable to drugstore options and significantly less than equivalently formulated dermatologist-marketed Western alternatives. There is no smaller travel size offered. For shoppers building a sensitive-skin routine on a budget, this is one of the most defensible cleanser purchases in the entire K-beauty category, and combining it with the brand's Chamomile Toner and Cicaful Ampoule produces a strong three-step routine well under sixty dollars total.
Who Should Buy
Normal, sensitive, combination, oily, and acne-prone skin types looking for a fragrance-free, amino-acid-surfactant foaming cleanser at an honest price. Especially valuable for shoppers managing acne or sensitivity who want a gentle daily wash with meaningful botanical support, and for anyone building a budget K-beauty sensitive-skin routine.
Who Should Skip
Very dry skin types who would prefer a creamier, non-foaming cleanser, anyone who needs a single cleanser to handle heavy waterproof makeup without an oil-cleanse pre-step, and shoppers in regions where Beplain availability is limited and shipping costs erode the value math.

Background
The Why
Beplain launched the Greenful Cleansing Foam (also sold as the Mung Bean pH-Balanced Cleansing Foam) shortly after the brand's 2017 founding, building it around the same ingredient-led, single-hero philosophy that defines the Chamomile Toner and Cicaful Ampoule. The cleanser became one of the brand's strongest-selling products in international K-beauty channels.
About Be Plain Emerging Brand (2–5 years)

Myth vs. Reality
Myths
Myth
Foaming cleansers always strip the skin.
Reality
The historical reputation of foaming cleansers comes from formulations built on harsh sulfates without humectants. Modern amino-acid-surfactant cleansers with glycerin at position one — like this one — produce a comfortable foam without disrupting the barrier.
FAQ
FAQ
Is Beplain Greenful Cleansing Foam good for sensitive skin?
Yes. The formula is fragrance-free, alcohol-free, and built on two gentle amino-acid surfactants (sodium cocoyl glycinate and sodium lauroyl glutamate) with glycerin at position one. The high mung bean and Centella content adds calming support, making it one of the better foaming options in the K-beauty sensitive-skin category.
Does this cleanser remove makeup?
It will lift sunscreen and lightweight day makeup easily, but heavy or waterproof makeup needs an oil cleanser or balm first. As a second cleanse it works beautifully; as a first cleanse on a full makeup day it falls short.
Is this cleanser fungal acne safe?
Yes. The formula contains no fatty acids, esters, or oils that feed Malassezia, making it appropriate for people managing fungal acne — a real advantage over the brand's Bamboo Hydrating Cream and many competing K-beauty cleansers.
Can I use this cleanser twice a day?
Yes. The amino-acid surfactant system is mild enough for twice-daily use without disrupting the skin barrier. The position-one glycerin prevents the post-wash tightness that would otherwise discourage daily double duty.
Is it pregnancy-safe?
Yes. There are no retinoids, salicylates, or hormone-disrupting ingredients in the formula. Appropriate for use throughout pregnancy and breastfeeding.
What does the mung bean extract actually do?
Mung bean carries flavonoids and polyphenols including caffeic acid, contributing antioxidant and mild soothing benefits. At 33% concentration it is delivering meaningful contact during the brief cleansing window — far more than the typical fractional-percentage botanical-as-marketing approach.
How long does the tube last?
The 80ml tube lasts about six to eight weeks with twice-daily use. The 160ml size is available for committed users at slightly better per-milliliter value.
