What Is Morus Bombycis Stem Extract?
Morus Bombycis Stem Extract comes from the woody stems of the mulberry tree Morus bombycis in the Moraceae family. Those stems are naturally rich in plant compounds such as flavonoids, stilbenes and other polyphenols that help the tree defend itself against stress and microbes. Records show mulberry parts have been valued in East Asian textile dyeing and folk skincare for centuries, which led modern formulators to study the stem for its protective and soothing properties. To obtain the extract, harvested stems are cleaned, dried, milled then steeped in a skin-safe solvent like water or glycerin. The liquid is filtered and concentrated, producing a brownish botanical extract that slots easily into water-based phases of cosmetics. You will spot it in sheet masks, anti-aging serums, brightening essences, lightweight moisturizers, clarifying toners and even scalp tonics where a gentle botanical boost is wanted.
Morus Bombycis Stem Extract’s Cosmetic Benefits/Uses
Formulators choose this multifunctional botanical for several helpful reasons:
- Antimicrobial – helps keep formulas bacteria balanced and supports blemish-prone or flaky skin by limiting surface microbes
- Antioxidant – supplies polyphenols that neutralize free radicals which can contribute to dullness and premature lines, aiding in overall skin vitality
- Astringent – gives a light tightening feel that can reduce the look of enlarged pores and excess oil making it handy in toners and oil-control products
- Emollient – leaves a soft conditioned finish on skin or hair improving comfort and smoothness without a heavy film
Who Can Use Morus Bombycis Stem Extract
This extract suits most skin types including normal, oily and combination complexions thanks to its lightweight texture and antimicrobial antioxidants. Sensitive skin generally tolerates it well because the polyphenols are calming, though the mild astringency could feel tight on very dry or barrier-compromised skin so those users may want to pair it with a richer moisturizer.
The ingredient is plant derived and free of animal by-products so it aligns with vegan and vegetarian values. No common animal-based processing aids are used during extraction.
Current data shows no specific hazards for pregnant or breastfeeding women when the extract is used topically at cosmetic levels, but this is not medical advice. Expectant or nursing mothers should run any new skincare routine past their doctor to stay on the safe side.
Morus Bombycis Stem Extract is not known to cause photosensitivity and can be used in day or night formulas. It blends smoothly with other common actives and does not interfere with mineral or chemical sunscreens.

Comedogenic Rating
Rating: 0 / 5
Morus Bombycis Stem Extract is almost entirely water soluble and contains virtually no heavy oils or waxes so it has little chance of blocking pores. Its polyphenols are lightweight and rinse clean without leaving an occlusive film which is why formulators place it in toners serums and gels rather than thick creams. This makes it well suited for acne-prone or breakout-prone skin.
Keep in mind that overall product composition matters. If the extract sits in a rich balm or oil-heavy formula the finished product could still clog pores even though the extract itself does not.
Summary
Morus Bombycis Stem Extract delivers four key perks: it suppresses unwanted microbes, sweeps up free radicals, gives a mild pore-tightening feel and leaves skin or hair feeling soft. These benefits come from the plant’s natural flavonoids and other polyphenols which neutralize oxidative stress, disturb bacterial membranes and create a light protective film on the surface.
While not a headliner like vitamin C or niacinamide this mulberry stem extract is quietly gaining traction in sheet masks clarifying toners and lightweight moisturizers because it offers several useful actions without heaviness or fragrance issues.
Current research and cosmetic usage levels rate it as a very safe ingredient with low irritation risk. As with any new skincare it is smart to patch test a fresh product first to be sure your skin agrees.
