Ingredient review
Mulberry Leaf & Root Extract
INCI: Morus Bombycis Leaf/Root Extract
A gentle botanical extract that helps protect skin from environmental stress and may support a more even skin tone.
In plain English
Mulberry leaf and root extract is a plant-based ingredient that contains natural compounds called flavonoids and polyphenols. These compounds act as antioxidants, meaning they help neutralize unstable molecules (free radicals) that can damage skin cells and accelerate aging. In skincare, it's often used to help brighten the complexion and reduce the appearance of dark spots, without the harsh side effects of some chemical brighteners.

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

Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
An extract derived from the leaves and roots of the mulberry tree (Morus bombycis), a species native to East Asia. It is rich in antioxidants like resveratrol, quercetin, and mulberroside A.
How it works
The extract works primarily by scavenging free radicals, which reduces oxidative stress on the skin. It also inhibits the activity of tyrosinase, an enzyme involved in melanin production, which can help fade hyperpigmentation and even out skin tone over time.
Pros
Gentle antioxidant
Provides antioxidant protection without the irritation that some stronger actives (like pure vitamin C) can cause, making it suitable for sensitive skin.
Natural brightening support
May help fade dark spots and even out skin tone by gently inhibiting melanin production, offering a milder alternative to hydroquinone.
Cons and cautions
Modest evidence
While lab studies show promise, there are fewer large-scale human trials confirming its brightening and anti-aging effects compared to more established ingredients.
Variable potency
The effectiveness depends heavily on the extraction method and concentration used in a product, so results can vary between brands.
Best for
- Anyone looking for a gentle antioxidant to protect against pollution and UV stress
- Those with mild hyperpigmentation or uneven skin tone seeking a natural brightener
Use caution if
- Individuals with known allergies to mulberry or related plants (rare)
