The 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 analysis.

Ingredient Role Evidence Flag
Mung Bean Extract (Vigna Radiata Seed Extract)](/ingredients/mung-bean-extract) (33%) FLAGGED
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
Caution
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
OK
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.

The science.

The Science

This cleanser uses amino-acid surfactants — sodium cocoyl glycinate and sodium lauroyl glutamate — which peer-reviewed evidence shows are gentler than traditional sulfates. Both compounds have lower critical micelle concentrations and less affinity for skin proteins than anionic sulfates like SLS. This means they disrupt the stratum corneum lipid bilayer less during cleansing. Studies on amino-acid-surfactant cleansers show reduced post-wash transepidermal water loss and better sensory comfort metrics than identical formulas using harsher surfactants.

Placing glycerin at INCI slot one is the most clinically meaningful design choice. Glycerin in a rinse-off product does one job: it leaves a measurable residual humectant load on the skin surface after rinsing to prevent the post-wash tightness found in stripped formulations. Studies on glycerin-containing cleansers show improved after-wash hydration metrics compared to identical formulas without glycerin. 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. Mung bean contains flavonoids and polyphenols, including caffeic acid, vitexin, and isovitexin, which show antioxidant and mild anti-inflammatory activity in laboratory studies. Clinical work on topical mung bean preparations is more limited than for the other actives in the formula, but at 33% concentration, its 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; however, individual contributions at low concentrations are modest. Including 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 philosophy.

Dermatologist Perspective

Dermatologists generally recommend amino-acid-surfactant cleansers with humectant-forward formulations as first-line options 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 of reactive or inflammatory skin. Korean indie brand cleansers receive less direct dermatologist endorsement than legacy clinical brands, but this product's formulation principles match what board-certified dermatologists recommend for daily use in sensitive-skin patients. Common clinical caveats involve makeup removal expectations and the need for a second-cleanse oil step on heavy makeup days.

How to use

Apply a pea-sized amount to wet hands. Rub between palms to create a soft, dense lather, then massage onto damp skin in circles for 30-60 seconds. Rinse with lukewarm water; hot water reduces the formula's gentleness. Pat dry with a clean towel and apply your next steps immediately. On full makeup days, use an oil cleanser or balm first, then use this foam as the second cleanse. Use in the morning and evening without over-stripping.

Value assessment

At $16 for 80ml, the price is competitive and offers one of the best formulation-to-price ratios in the K-beauty foaming cleanser category. The 160ml size has better per-milliliter value for frequent users. Using it twice daily costs roughly $5-8 per month, matching drugstore prices and undercutting Western dermatologist-marketed alternatives with similar formulations. No smaller travel size exists. For budget-conscious sensitive-skin routines, this is a top cleanser choice in the K-beauty category. Pairing it with the brand's Chamomile Toner and Cicaful Ampoule creates a three-step routine for well under sixty dollars total.

Who should buy

Normal, sensitive, combination, oily, and acne-prone skin types want a fragrance-free, amino-acid-surfactant foaming cleanser at an honest price. This cleanser works well for acne or sensitivity management and provides botanical support. It fits budget K-beauty sensitive-skin routines.

Who should skip

Users with very dry skin who want a creamier, non-foaming cleanser, anyone needing one cleanser to remove heavy waterproof makeup without an oil-cleanse pre-step, and shoppers in regions where Beplain availability is limited and shipping costs reduce the value.

The backstory.

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

Common myths.

Myth

Foaming cleansers always strip the skin.

Reality

Foaming cleansers historically rely on harsh sulfates and lack humectants. Modern amino-acid-surfactant cleansers use glycerin at position one — like this one — to produce comfortable foam without disrupting the barrier.

10 · Common questions

FAQ.

Is Beplain Greenful Cleansing Foam good for sensitive skin?

Yes. The formula is fragrance-free, alcohol-free, and uses two gentle amino-acid surfactants (sodium cocoyl glycinate and sodium lauroyl glutamate) with glycerin at position one. High mung bean and Centella content calms skin, making it a top foaming option in the K-beauty sensitive-skin category.

Does this cleanser remove makeup?

It lifts sunscreen and lightweight day makeup easily. Heavy or waterproof makeup requires an oil cleanser or balm first. It works well as a second cleanse, but falls short as a first cleanse on a full makeup day.

Is this cleanser fungal acne safe?

Yes. The formula lacks fatty acids, esters, or oils that feed Malassezia. This makes it safe for fungal acne, giving it an 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 and does not disrupt the skin barrier. The position-one glycerin prevents post-wash tightness that would otherwise stop daily double duty.

Is it pregnancy-safe?

Yes. The formula has no retinoids, salicylates, or hormone-disrupting ingredients. It is safe for use during pregnancy and breastfeeding.

What does the mung bean extract actually do?

Mung bean has flavonoids and polyphenols like caffeic acid, which provide antioxidant and mild soothing benefits. At 33% concentration, it makes meaningful contact during the brief cleansing window—much more than the typical fractional-percentage botanical-as-marketing approach.

How long does the tube last?

The 80ml tube lasts six to eight weeks if used twice daily. The 160ml size offers better per-milliliter value for committed users.
