Plant extract

What is Mung bean extract?

Mung bean extract is a water based extract of the mung bean, which Korean labels call nokdu. It goes into the water phase as a botanical additive. Like other plant extracts it is a mixture rather than one defined compound, so what is in it depends on how the supplier made it.

What does the research actually show?

Two lists, taken from published studies on this ingredient. The first is what those studies support. The second is what they do not, which is where advertising most often runs ahead of the evidence.

Was this exact ingredient the one tested?

No source located tests a plain Vigna Radiata (Mung Bean) Extract on human skin for a cosmetic efficacy endpoint.

MUN-S1 exposes human skin to a mung bean sprout extract but its human component is a safety patch test, not an efficacy measurement.

What the evidence supports

Antioxidant activity of mung bean sprout water extract, in chemical assays.
DPPH scavenging above 85% at every tested shoot length, total antioxidant capacity above 4.0, and ferrous chelation near 80% at day one of sprouting (MUN-S1).
Sources: 1
Protection of human skin cells against oxidative injury, in vitro.
Hull phenolic extracts and their isolated compounds protected HaCaT and human skin fibroblast viability under H2O2 stress (MUN-S2).
Sources: 2
Human skin tolerance of a mung bean sprout extract.
The red blood cell hemolysis test, chick chorioallantoic membrane assay and human skin patch test together led the authors to conclude that "extracts of mung bean sprouts are safe" (MUN-S1, 7 words) and usable as additives in antiaging cosmetic products.
Sources: 1

What the evidence does not support

Claim: mung bean extract brightens skin, evens tone, or reduces pigmentation.
The tyrosinase and melanogenesis work belongs to Pracparatum mungo, a fermented preparation of mung bean mixed with other Chinese medicines (MUN-S3), so the effect cannot be attributed to mung bean.
Sources: 3
Claim: mung bean is proven for skin by research.
Directly contradicted by an explicit source statement.
Claim: mung bean calms or purifies pores and clears blemishes.
Sources: 4
Claim: mung bean's vitexin content delivers an anti-aging benefit in a finished product.
Isovitexin and vitexin were the most protective of eight isolated compounds against H2O2 damage in cultured cells (MUN-S2), but they were tested as isolated compounds from a hull extract, not as constituents of a cosmetic mung bean extract at whatever level such an extract contains.
Sources: 2
Claim: mung bean is antioxidant, therefore it is anti-aging on skin.
The antioxidant measurements are chemical assays and cell viability endpoints (MUN-S1, MUN-S2).
Sources: 1, 2
Claim: mung bean extract is confirmed safe by an expert panel.
No CIR safety assessment covering Vigna Radiata (Mung Bean) Extract was located.
