Hydrolyzed White Mulberry Leaf Extract
INCI: Hydrolyzed Morus Alba Leaf Extract
A gentle, antioxidant-rich botanical extract that helps calm skin and defend against environmental stress, though research on its hydrolyzed form is still emerging.
In plain English
This is an extract from white mulberry leaves that has been hydrolyzed, meaning it's broken down into smaller pieces so your skin can absorb it more easily. It's known for providing antioxidant protection (helping to fight damage from pollution and UV exposure) and for its soothing properties, making it a nice addition to products for sensitive or stressed skin.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk

Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Hydrolyzed Morus Alba Leaf Extract is derived from the leaves of the white mulberry tree (Morus alba). The hydrolysis process uses water and enzymes to break down larger molecules like proteins and polysaccharides into smaller, more skin-absorbable peptides and sugars.
How it works
Once applied, the hydrolyzed extract delivers antioxidant compounds (such as flavonoids and phenolic acids) that help neutralize free radicals, reducing oxidative stress on the skin. It also has mild anti-inflammatory effects, which can help calm redness and irritation.
Pros
Gentle antioxidant
Provides free-radical defense without the irritation potential of some stronger antioxidants, making it suitable for sensitive skin types.
Soothing properties
Helps calm redness and inflammation, which can improve overall skin comfort and appearance over time.
Cons and cautions
Limited research on hydrolyzed form
Most studies focus on non-hydrolyzed mulberry leaf extract, so the specific benefits of the hydrolyzed version are less well-documented.
Variable potency
The concentration of active compounds can vary between batches, leading to inconsistent results in finished products.
Best for
- People with sensitive or easily irritated skin looking for a gentle antioxidant
- Those wanting to add a soothing, brightening botanical to their routine
Use caution if
- Individuals with known allergies to mulberry or related plants (rare)
Usage tips
Safety summary
Hydrolyzed Morus Alba Leaf Extract is considered safe for topical use with a low risk of irritation or allergic reaction. Patch testing is recommended for those with plant allergies.
Research notes
While mulberry leaf extract has demonstrated antioxidant and anti-inflammatory activity in lab studies, direct clinical evidence for the hydrolyzed form in human skin is limited. Most support comes from traditional use and in vitro research.
