What Is Morus Bombycis Leaf/Root Extract?
Morus Bombycis Leaf/Root Extract is a botanical ingredient obtained from the leaves and roots of the mulberry tree Morus bombycis, a member of the Moraceae family. The raw plant parts are rich in phenolic compounds, flavonoids and mild organic acids that give the extract its skin friendly properties. Mulberry has long featured in traditional East Asian skincare rituals for brightening and refining the complexion, which led formulators to explore a standardized extract suitable for modern cosmetics.
To create the extract, harvested leaves and roots are cleaned, dried then macerated in a solvent such as water or a water-glycol mixture. The liquid is filtered to remove plant solids, concentrated under low heat to preserve active molecules then stabilized for use in finished products. This gentle process keeps the beneficial polyphenols intact while removing unwanted impurities.
Today you will commonly find Morus Bombycis Leaf/Root Extract in hydrating masks, daily moisturizers, toners, anti aging serums and targeted treatments aimed at refining skin texture or reducing the look of enlarged pores.
Morus Bombycis Leaf/Root Extract’s Cosmetic Benefits/Uses
Formulators turn to this extract for two primary reasons
- Astringent – Its natural tannin content helps tighten the appearance of pores and reduce excess surface oil giving skin a smoother more refined finish. This makes the extract useful in toners, clarifying lotions and lightweight gels designed for combination or oily complexions.
- Skin Conditioning – The flavonoids and sugars in the plant deliver a mild soothing effect and support the skin’s moisture balance. When used in creams masks or serums the extract can leave skin feeling softer and looking refreshed.
Who Can Use Morus Bombycis Leaf/Root Extract
This extract suits most skin types. Oily and combination complexions tend to benefit most thanks to its pore tightening effect, while normal and dry skin can also enjoy its soothing properties as long as it is paired with a good moisturizer. Very sensitive skin usually tolerates it, though the natural tannins may cause a slight tightening feel for some users.
The ingredient is plant based with no animal derivatives, so it is appropriate for vegans and vegetarians. The solvents typically used in its preparation are also non animal sourced in reputable formulations.
Current research shows no specific risks for pregnant or breastfeeding women when the extract is applied topically in cosmetic amounts. This is not medical advice; anyone who is expecting or nursing should show the full product list to a healthcare professional before adding it to a routine.
The extract is not known to cause photosensitivity, so it can be worn both day and night without raising sun sensitivity. As with any astringent, pairing it with a daily sunscreen remains a smart habit for overall skin health.
Potential Side Effects/Adverse Reactions
Reactions to topical Morus Bombycis Leaf/Root Extract differ from person to person. The following points outline potential side effects that could occur, though most users experience none of them when the ingredient is formulated and used correctly.
- Temporary dryness or tightness
- Mild redness or warmth right after application
- Stinging sensation on compromised or freshly exfoliated skin
- Allergic contact dermatitis in those sensitive to mulberry or related plants
- Increased irritation if layered with high strength acids or alcohol heavy products
If any of the above effects develop and persist stop use and consult a medical professional.
Comedogenic Rating
Rating: 1/5
Morus Bombycis Leaf/Root Extract is mostly composed of water-soluble polyphenols and sugars with very little lipid content, so it does not readily clog pores. Its mild astringent action can even help reduce surface oil, further lowering the chance of buildup inside follicles. Because of this it is generally considered safe for acne-prone or breakout-prone skin.
No large-scale studies link the extract to comedones, though final product texture and the presence of other heavier ingredients will influence overall pore-clogging potential.
Summary
Morus Bombycis Leaf/Root Extract acts as an astringent and skin conditioner. Tannins tighten the appearance of pores and curb excess sebum while flavonoids and natural sugars calm skin and support hydration. These combined actions leave the complexion looking smoother and feeling refreshed.
The extract is moderately popular in modern formulations, showing up most often in toners masks and lightweight moisturizers aimed at oily or combination skin. It is not yet a headline star like green tea or niacinamide but its gentle nature keeps it on the ingredient list of many K-beauty inspired products.
Overall safety is high with few reported reactions. Still, individual sensitivities vary, so it is wise to patch test any new product containing Morus Bombycis Leaf/Root Extract before full-face use.
