Ingredient review
Mung Bean Starch
INCI: Phaseolus Radiatus Seed Starch
A gentle, plant-based starch that helps absorb excess oil and improve product texture without clogging pores.
In plain English
Mung bean starch is a fine powder made from ground mung beans. In skincare, it works like a sponge to soak up extra oil and moisture on your skin, leaving a smooth, matte finish. It's often used in face powders, dry shampoos, and masks to give a silky feel without being heavy or greasy. Because it's natural and mild, it's a popular choice for sensitive or oily skin types.

What it is
A natural starch extracted from the seeds of the mung bean plant (Phaseolus radiatus, also known as Vigna radiata). It is a fine, white powder composed mainly of polysaccharides.
How it works
When applied to the skin, mung bean starch acts as an absorbent, drawing in excess sebum and moisture. It also helps thicken and stabilize product formulas, giving them a smooth, non-sticky texture. In powders, it provides a soft-focus effect by scattering light.
Pros
Gentle oil control
Mung bean starch soaks up excess sebum without stripping the skin, making it ideal for shine-prone areas.
Natural and skin-friendly
As a plant-derived starch, it is generally well-tolerated and less likely to cause irritation compared to some synthetic powders.
Cons and cautions
Can be drying for dry skin
Because it absorbs moisture, those with dry skin may find it too mattifying or dehydrating if used in large amounts.
Texture sensitivity in formulas
If not finely milled or properly combined, it can clump or feel gritty, affecting the user experience.
Best for
- People with oily or combination skin looking for a natural oil absorber
- Those who prefer plant-based, gentle ingredients in their powders and masks
Use caution if
- Individuals with very dry or dehydrated skin may find it too absorbent
