What it is
Mulberry leaf extract is a plant-derived ingredient obtained from the leaves of the mulberry tree (Morus species). It contains flavonoids, phenolic acids, and other bioactive compounds that give it antioxidant and soothing properties.
How it works
In a cosmetic product, mulberry leaf extract works primarily as an antioxidant, neutralizing free radicals that can cause premature aging. It also has anti-inflammatory effects, helping to reduce redness and calm sensitive skin. Some compounds in the extract may also inhibit tyrosinase, an enzyme involved in melanin production, which can help with brightening and evening out skin tone.
Pros
Gentle antioxidant
Provides protection against free radicals without causing irritation, making it suitable for sensitive skin.
Soothing properties
Helps calm redness and inflammation, which can be beneficial for conditions like mild rosacea or post-acne irritation.
Cons and cautions
Modest brightening effect
While it may help with skin tone, its brightening action is milder than dedicated brighteners like vitamin C or kojic acid.
Variable potency
The concentration and quality of active compounds can differ between products, leading to inconsistent results.
Best for
- Anyone looking for a gentle antioxidant to protect skin from daily pollution and UV stress
- People with sensitive or reactive skin who want a soothing, brightening ingredient
Use caution if
- Individuals with a known allergy to mulberry or related plants should patch test first
Usage tips
Safety summary
