What Is Morus Bombycis Extract?
Morus Bombycis Extract is a botanical ingredient derived from the whole mulberry plant Morus bombycis, a member of the Moraceae family. The plant naturally contains flavonoids, phenolic acids, stilbenes and trace minerals that give it soothing and protective qualities. Mulberry leaves were famously cultivated to feed silkworms, and the plant has been used in traditional beauty rinses for centuries. Modern cosmetic chemists capture its benefits by macerating the fresh or dried plant in water, glycerin or a mild alcohol blend, then filtering and concentrating the liquid to yield a stable extract that retains its active compounds.
You will most often spot Morus Bombycis Extract in lightweight serums, brightening masks, pore-refining toners, anti-aging moisturizers, scalp tonics and leave-in hair conditioners where it lends calming, protective and balancing properties.
Morus Bombycis Extract’s Cosmetic Benefits/Uses
Formulators value this extract for the multitasking boost it gives to skin and hair products.
- Anti-Seborrheic: Helps regulate excess oil on skin and scalp which can reduce shine, clogged pores and greasy roots
- Antimicrobial: Limits the growth of blemish-causing or odor-causing microbes supporting clearer skin and a fresher scalp
- Antioxidant: Neutralizes free radicals from pollution and UV exposure helping to protect skin proteins and preserve overall skin tone
- Astringent: Provides a gentle tightening effect that can minimize the look of enlarged pores and improve skin smoothness
- Hair Conditioning: Leaves strands softer and more manageable while soothing the scalp which can enhance overall hair appearance
Who Can Use Morus Bombycis Extract
Morus Bombycis Extract is generally well tolerated by most skin types. Its oil-balancing yet soothing nature makes it especially helpful for oily, combination and acne-prone skin while the antioxidant content supports normal and mature skin. Sensitive skin tends to accept the extract thanks to its gentle profile though very dry complexions may prefer it paired with richer moisturizers to avoid a tight feeling.
The ingredient is entirely plant derived with no animal by-products so it fits vegan and vegetarian preferences.
No data indicate a direct risk for pregnant or breastfeeding women when the extract is used topically at customary cosmetic levels. This is not medical advice and anyone who is pregnant or nursing should review all skincare products with a qualified health professional to be sure they are comfortable with every ingredient.
Morus Bombycis Extract does not make skin more prone to sunburn and is considered non-photosensitizing. It can be layered under sunscreen without issue. The extract also plays nicely with common actives like niacinamide, hyaluronic acid and most peptides so it is easy to slot into existing routines.
Potential Side Effects/Adverse Reactions
Responses to topical Morus Bombycis Extract vary from person to person. The following are potential side effects that could occur although they are uncommon when the ingredient is properly formulated and used as directed.
- Mild stinging or burning: Most likely when applied to compromised or freshly exfoliated skin
- Temporary redness: Usually subsides quickly once the product is removed
- Possible in very dry skin if the formula lacks sufficient emollients
- Allergic contact dermatitis: Itching, rash or swelling in individuals allergic to mulberry or related plants
- Eye irritation: Watering or discomfort if the product accidentally gets into the eyes
Discontinue use and seek advice from a healthcare professional if any persistent discomfort or adverse reaction occurs.
Comedogenic Rating
Rating: 1 (very low)
Morus Bombycis Extract is largely composed of water soluble polyphenols and sugars that do not leave an occlusive film on skin. It contains only trace amounts of fatty or waxy constituents so the likelihood of pore blockage is minimal. This makes the extract a comfortable option for people who are prone to acne or breakouts.
As with any formula, the overall comedogenicity depends on the full ingredient deck. If Morus Bombycis Extract is blended into an oily balm or heavy cream the finished product could still clog pores even though the extract itself is low risk.
Summary
Morus Bombycis Extract delivers five key functions: it helps control excess oil, discourages blemish causing microbes, scavenges damaging free radicals, provides a mild pore tightening effect and leaves hair softer and calmer. These benefits stem from its natural mix of flavonoids, phenolic acids, stilbenes and minerals that offer antioxidant power, gentle astringency and soothing support.
The extract is a quiet achiever rather than a headline act. You will see it pop up in select K-beauty toners and indie serums but it has not reached the mainstream popularity of ingredients like niacinamide or vitamin C. Still formulators appreciate its multitasking profile and clean plant origin which is nudging its use upward.
Overall safety is considered high when the extract is used at typical cosmetic levels. Most users experience no irritation yet it is always smart to patch test a new product to check personal tolerance before applying it to a larger area.
