Ingredient review
Bitter Melon Leaf Powder
INCI: Momordica Charantia Leaf Powder
A gentle plant-based antioxidant that may help calm skin, but research is still early and benefits are not yet proven in human studies.
In plain English
Bitter melon leaf powder is made by drying and grinding the leaves of the bitter melon plant, a vegetable common in Asian cooking. In skincare, it is used as a source of antioxidants—substances that help protect skin from damage caused by pollution and UV rays. It may also have mild soothing effects, making it a nice addition for sensitive or irritated skin. However, most of what we know comes from lab studies, not large human trials, so it's best to see it as a supportive ingredient rather than a star performer.

Research notes
Research on topical bitter melon leaf extract is preliminary. In vitro studies show antioxidant and anti-inflammatory activity, but human clinical trials are needed to confirm efficacy and optimal concentrations for skincare.
Common label clues
- Typical concentration
- 0.1% to 1% in leave-on products; up to 5% in rinse-off products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU when used as a botanical ingredient. No specific restrictions apply.
- Common uses
- Face masks, Cleansers, Serums
- Environmental note
- Bitter melon is widely cultivated in tropical regions and is not considered an endangered species. Sourcing from sustainable farms is recommended.
Good to know
- Bitter melon is also used in traditional medicine for its anti-inflammatory properties, but this does not guarantee the same effects in skincare.
- The powder form may not dissolve completely in water-based formulas, so it is often used in masks or suspended in thicker creams.
