Beplain Mung Bean Cleanser Review 2026: Genuinely Gentle?

Most foaming cleansers force a trade. You either get a squeaky clean face or you keep your moisture barrier intact. Rarely both.

That tight, papery feeling after washing is not a sign of cleanliness. It is a sign your skin barrier just took a hit.

Beplain built its Mung Bean pH-Balanced Cleansing Foam around that exact complaint. The brand promises a sub-acidic wash that clears sebum and fine dust without the post-rinse tightness.

I used it twice daily for four weeks, cross-checked the current ingredient list, and read through hundreds of buyer comments. Here is what actually holds up.

In a Nutshell

• A genuinely low-pH formula. The cleanser sits in the sub-acidic range close to skin’s own 4.5 to 5.5, so it rinses clean without wrecking your acid mantle. This is the single biggest reason it earns repeat purchases.
• Amino acid surfactants replace sulfates. Sodium Cocoyl Glycinate and Sodium Lauroyl Glutamate do the cleansing work. Both are mild, foam beautifully, and are used in baby washes.
• Mung bean does double duty. Vigna Radiata Seed Extract handles pore purification while Phaseolus Radiatus Seed Powder at roughly 9,000ppm adds a whisper of physical polish. You feel the grit only if you look for it.
• Barrier support is real, not decorative. Ceramide NP, Sodium Hyaluronate, Centella Asiatica, and Allantoin sit low on the list but soften the finish measurably.
• Best for oily, combination, and normal skin. Dry and dehydrated types report tightness. This is the most consistent complaint across every review platform.
• It will not remove sunscreen alone. Plan on an oil cleanser first at night. Multiple long-term users confirm this.

Beplain is a Korean brand built on short, purposeful ingredient lists. This cleanser is its flagship and its bestseller.

The credentials are not invented. It took awards at the 2020 and 2021 Olive Young Beauty Awards and ranked number one in the cleansing foam category at the Hwahae Beauty Awards.

The core pitch is simple. Korean-grown mung bean from Ochang, milled into powder and pressed into extract, cleans pores while the surrounding formula keeps water in the skin.

You get 80ml in the standard tube and 160ml in the value size. Pricing typically lands near thirteen dollars for the smaller tube.

It is fragrance-free, which matters more than most people realize. Added fragrance in a rinse-off product delivers almost no benefit and plenty of reactivity risk.

The formula was quietly reformulated. The current version includes Alcohol and Sodium Benzoate that earlier batches did not list. More on that later, because the internet has strong opinions about it.

Unboxing And First Impressions

There is no ceremony here. A slim green carton, a soft-touch tube inside, an insert with Korean and English directions.

The tube is matte sage green with white type. It looks quiet next to louder K-beauty packaging, which I count as a plus.

The nozzle is narrow. That sounds trivial until you use a cleanser with a wide opening and waste half a tube in a month.

A pea-sized amount is genuinely enough. I squeezed too much on day one out of habit and spent an extra thirty seconds rinsing.

The tube stands on its cap. Small design decision, real daily benefit, especially in a crowded shower caddy.

The 80ml size is TSA-friendly and fits a dopp kit without argument. The 160ml is better value but needs shelf space.

Squeeze resistance is moderate. Near the end of the tube you can flatten and roll it cleanly, so waste is minimal.

Nothing about the presentation feels premium. Nothing feels cheap either. It reads like a product spending its budget on the formula rather than the box.

The Ingredient List Decoded

Glycerin takes the first slot. That is unusual and deliberate, since most cleansers lead with water.

Then come the surfactants. Sodium Cocoyl Glycinate, Sodium Lauroyl Glutamate, and Lauryl Betaine are amino acid and betaine derived, not sulfates.

Mung bean appears twice. The seed powder sits around 9,000ppm and the seed extract near 3,300ppm, so these are functional amounts rather than label decoration.

The soothing cast is deep. Centella Asiatica Extract, Allantoin, Chamomilla Recutita, and Phellodendron Amurense Bark Extract all appear.

That last one deserves attention. Amur cork tree bark has documented anti-inflammatory activity and antibacterial effect against acne-causing bacteria.

Barrier ingredients close out the list. Ceramide NP, Sodium Hyaluronate, and Hydrogenated Lecithin sit near the bottom.

Be honest about that placement. Ingredients in the final third of a rinse-off product contribute a softer after-feel, not clinical barrier repair.

Camellia Sinensis Leaf Powder and Curcuma Longa Root Extract add antioxidant value. Again, contact time is under a minute, so temper expectations.

COSRX Low pH Good Morning Gel Cleanser

Texture, Scent, And How It Lathers

Out of the tube it is a thick, pale cream. Denser than a gel, lighter than a balm cleanser.

Add warm water and it transforms fast. Two or three seconds of rubbing produces a dense, small-bubble foam that holds its shape.

The lather quality is the strongest sensory feature. It feels cushioned rather than squeaky, closer to a whipped cream than a soap suds.

Scent is essentially absent. Get close and you catch a faint, starchy bean smell that fades the moment water hits it.

Fragrance-sensitive users will appreciate that. There is nothing floral, citrus, or synthetic happening here.

You can feel the mung bean powder if you press your fingers together. On the face it is imperceptible during a normal thirty-second wash.

Rinsing takes slightly longer than a gel cleanser. Several users note this, and I agree, especially around the hairline.

The finish is soft and slightly cushioned. Not slippery, not stripped. My skin felt comfortable for roughly two minutes before I applied toner.

My Four Week Test

I have combination skin with an oily T-zone and dry cheeks in winter. I tested morning and evening.

Mornings were the standout. Used alone on bare skin, it removed overnight oil and left nothing behind.

Evenings needed help. Used over sunscreen without an oil cleanse first, it left a faint film across my nose and jaw.

That film is a recurring theme in user reports. It disappears entirely if you double cleanse.

By week two my T-zone oil production felt more even. Not dramatically reduced, just less frantic by mid-afternoon.

Blackheads on my nose looked marginally softer. I credit the mild physical polish from the powder rather than any pore-clearing magic.

No breakouts, no stinging, no redness across twenty-eight days. My skin tolerates most things, so read that as a low irritation signal rather than proof.

Around week three my cheeks felt slightly tight after evening washes. Following immediately with toner solved it completely.

Who This Cleanser Is Not For

I want to be direct here, because the marketing says all skin types and the reviews say something more specific.

Very dry or dehydrated skin should approach carefully. The most common negative review describes tightness and, in a few cases, flaking after twice-daily use.

One reviewer with dry, sensitive skin reported active irritation from morning and evening use. Evening only would be the smarter starting point.

Anyone wanting a one-step routine should skip it. It does not reliably dissolve modern sunscreens or long-wear base makeup.

If you have a known chamomile allergy, check the list. Chamomile is soothing for most people and a genuine allergen for a small group.

Users on strong actives like tretinoin have mixed results. Some find it calming, others find the light exfoliation unwelcome on compromised skin.

If you dislike any grit whatsoever, the powder may bother you. It is subtle, but it exists.

Finally, if you want visible acne treatment, this is not that product. It is a supporting cleanser, not a spot treatment.

The Alcohol Question

This comes up constantly in forums, so let me address it plainly.

The reformulated version lists Alcohol around the fourteenth position. That placement suggests a concentration near or below one percent.

At that level, in a product you rinse off in under a minute, the drying risk is negligible. Alcohol in low amounts often acts as a solvent for plant extracts.

Users with dry, dehydrated skin have reported no issue with the current formula. That tracks with the chemistry.

The bigger flaw is different. This is a cleanser marketed on barrier support that still leaves some people feeling tight.

The cause is likely the combination of a thorough surfactant blend plus mild physical exfoliation, not the alcohol.

Sodium Benzoate also joined the list. It is a standard preservative and only functions properly at acidic pH, which incidentally confirms the low-pH claim.

My honest read: the reformulation is a minor step sideways, not a downgrade. The internet reaction outpaced the actual change.

Judge it by how your skin feels at day fourteen, not by ingredient list anxiety.

Pros And Cons

Here is the balance sheet after a month of daily use.

Pros

• Sub-acidic pH that respects the acid mantle, verified by both the brand and the preservative system used.
• Amino acid surfactants foam richly without the stripping feel of sulfate-based washes.
• Completely fragrance-free, which lowers reactivity risk for sensitive types.
• Meaningful concentrations of mung bean powder and extract, not trace amounts.
• Excellent value per milliliter, particularly in the 160ml size.
• Efficient nozzle and a pea-sized dose mean a tube lasts months.
• Genuine soothing cast from Centella Asiatica, Allantoin, and Phellodendron Amurense.

Cons

• Leaves a faint film if used over sunscreen without an oil cleanse first.
• Dry and dehydrated skin frequently reports post-wash tightness.
• Requires more rinsing time than a typical gel cleanser.
• Barrier ingredients like Ceramide NP sit too low to do heavy lifting in a rinse-off.
• Contains chamomile, a known allergen for a small subset of users.
• The exact pH figure is not printed on the packaging.
• Light physical exfoliation may not suit reactive or actively inflamed skin.

Where To Buy The Beplain Mung Bean Cleansing Foam

The 160ml tube is the better buy if you already know the formula agrees with you. Cost per use drops significantly.

Start with the 80ml if this is your first Beplain purchase. Two months of testing is enough to know.

Buy from the official brand storefront or an authorized K-beauty retailer. Counterfeit Korean cleansers are a documented problem on marketplace listings.

Check the batch code and expiry on the crimp seal when it arrives. Legitimate stock has clear printing, not smudged ink.

Prices fluctuate. The 80ml commonly sits near thirteen dollars and the 160ml near twenty, though retailer promotions move both.

Beplain also sells this in bundles with the mung bean cleansing oil. That pairing solves the sunscreen removal gap directly.

Shelf life after opening is typically twelve months. You will finish it well before that.

Store it out of direct shower steam if possible. Not critical, but heat cycling does no formula any favors.

Final Verdict

Is it genuinely gentle? Yes, with an asterisk.

The pH is right, the surfactants are mild, and the soothing ingredients are present in real terms. That is more than most cleansers at this price can claim.

The asterisk is skin type. Oily, combination, and normal skin will likely love it. Dry and dehydrated skin should test cautiously and follow with hydration immediately.

It is not a one-step solution. Treat it as the second step of an evening double cleanse and the only step of your morning routine.

What impresses me most is the restraint. There is no fragrance, no essential oil, no color, no gimmick.

What frustrates me is the gap between the marketing language and the lived experience. All skin types is optimistic. Most skin types is accurate.

I would repurchase the 160ml size. It has replaced two more expensive cleansers in my rotation.

For anyone rebuilding a barrier after harsh washes, this is a sensible, affordable, low-drama place to land.

Frequently Asked Questions

What is the actual pH of the Beplain Mung Bean cleanser?

Beplain describes it as sub-acidic without printing an exact figure. Independent testing by users consistently places it between 5.0 and 5.5, matching healthy skin.

The presence of Sodium Benzoate supports this, since that preservative only works reliably below pH 5.5.

Can it remove sunscreen and makeup on its own?

Not dependably. Users with oily skin repeatedly report residue after washing off modern sunscreens with this alone.

Use a cleansing oil or balm first at night. Reserve this as your morning wash and your second cleanse.

Is it safe for acne-prone skin?

Generally yes. Phellodendron Amurense Bark Extract has documented antibacterial activity against acne bacteria, and the formula is fragrance-free.

Several users with oily, acne-prone skin report improvement in blackheads. It supports acne care rather than treating it.

Does the mung bean powder exfoliate too aggressively?

No. The particles are finely milled and the concentration sits under one percent.

You feel a faint texture between your fingers, not on your face. Users with reactive skin should still limit use to once daily.

Will it work for dry skin?

It can, with adjustments. Use it in the evening only, keep the water lukewarm, and apply toner within thirty seconds of patting dry.

If tightness persists past two weeks, a cream or milk cleanser suits dry skin better.

Was the formula changed recently?

Yes. The current list includes Alcohol, Sodium Benzoate, Tocopherol, and Anthemis Nobilis that older versions did not.

Alcohol sits fourteenth, implying roughly one percent or less. The practical impact in a rinse-off product is minimal.

How does it compare to COSRX Low pH Good Morning Gel Cleanser?

The COSRX option is a lighter gel with tea tree and BHA, better suited to a fast morning rinse.

Beplain foams more richly and cleans more thoroughly. Choose Beplain for a fuller cleanse, COSRX for minimal morning contact.

How long does one tube last?

The 80ml tube lasted me roughly ten weeks at twice-daily use. The 160ml should comfortably cover four to five months.

A pea-sized amount is sufficient. Using more slows rinsing without improving the cleanse.
