beplain: The Korean Skincare Brand Built on Mung Bean
A Seoul-founded skincare label that pairs an ancient botanical ingredient with minimalist formulas for sensitive and pore-prone skin.
beplain is a Korean skincare brand founded in 2018 in Seoul, built on the philosophy "From nature, back to nature." According to the brand, it keeps formulas to a handful of plant-based actives, avoids unnecessary additives and uses biodegradable sugarcane-bagasse packaging. Its hero Mung Bean line is its best-known pore-care range.
Who beplain is for
If you have oily, combination, or congestion-prone skin and you are tired of routines that fight your face rather than work with it, beplain is a brand worth knowing. The brand describes its approach as minimalist, avoiding unnecessary additives and choosing ingredients intended to reduce the risk of irritation. Pore care is the territory beplain knows best, and the Mung Bean line is where that focus is sharpest. This beplain Korean skincare brand story starts with a very specific ingredient and follows it all the way through the product shelf.
Origin and philosophy
beplain is operated by the Seoul-based Moments Company, established in 2018. Its parent, Moments Company, is an affiliate of Birdview — the operator of Hwahae, Korea's large crowdsourced cosmetics-review app — and beplain was effectively built on top of that stream of user feedback. Their very first products, the Greenful pH-Balanced Cleansing Foam and the Cicaful Ampoule, were made based on customer data. That origin story matters: beplain did not start with a mood board. It started with real complaints about existing formulas, and it built answers to those complaints.
The word "plain" was chosen, per the founders, to feel ordinary and universal — a brand any age or gender could reach for without a regimen lecture. Guided by the philosophy "From nature, back to nature," the brand says it uses eco-friendly ingredients and sustainable packaging, including biodegradable packaging made from sugarcane bagasse.
What beplain is known for
beplain is a Korean minimalist skincare brand built around single-hero-ingredient formulas with a strict pH philosophy. Its main lines each orbit a core botanical: mung bean for pore and cleansing care, centella asiatica for barrier care in the Cicaful range, and mushroom-derived ingredients for renewal in the Chaga Regen line.
The Mung Bean line is the one that put the brand on the map. Mung bean has been used for cleansing since the Silla Dynasty. Mung bean has long been associated with purifying in Korea — there is even an old Korean saying that mung beans can remove a hundred toxins. Mung bean extract has a long history in Korean beauty rituals: it is mildly astringent, it tightens the appearance of pores without drying the skin out, and it has a soft, slightly earthy scent that signals "this is an ingredient, not a fragrance." beplain takes that ancient material and reformulates it through a modern lens — low-pH bases, peptide technology, and carefully chosen supporting actives.
According to the brand, beplain has received Olive Young Awards for five consecutive years, from 2021 through 2025. That is a meaningful benchmark: Olive Young is Korea's dominant health and beauty retail chain, and its annual awards reflect actual sales performance and shopper sentiment across a field of hundreds of competing brands.
The Mung Bean Pore Tight-Up Serum
The product featured on Kayty from beplain sits at the treatment end of the Mung Bean line. The Mung Bean Pore Tight-Up Serum is a gel-to-water serum designed specifically for pores that have been stretched and slackened — whether from chronic excess oil, heat, or simple aging of the pore walls.
