Ingredient review
Staghorn Sumac Leaf Extract
INCI: Rhus Typhina Leaf Extract
A gentle plant extract with antioxidant potential, but research on its skincare benefits is still limited.
In plain English
Staghorn sumac leaf extract comes from a tree native to North America. In skincare, it's used for its antioxidant properties, meaning it may help protect your skin from damage caused by environmental stressors like pollution and UV rays. It's also thought to have soothing qualities, making it a nice addition for sensitive skin types. However, most of the evidence comes from lab studies, not large human trials, so its effects are not as well-documented as more common antioxidants like vitamin C or green tea.

What it is
An extract derived from the leaves of Rhus typhina, commonly known as staghorn sumac. The leaves are rich in polyphenols, tannins, and flavonoids, which are natural compounds known for their antioxidant and anti-inflammatory activities.
How it works
The polyphenols in the extract help neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. By scavenging these free radicals, the extract may reduce oxidative stress and support the skin's natural repair processes. Its tannins also provide mild astringent and soothing effects, which can help calm irritated skin.
Pros
Natural antioxidant source
Rich in polyphenols that help fight free radicals, potentially reducing signs of aging and environmental damage.
Gentle for sensitive skin
Low irritation and comedogenic risk make it suitable for reactive or acne-prone skin types.
Cons and cautions
Limited human evidence
Most studies are lab-based; there are few clinical trials confirming its effectiveness on human skin.
Potential allergen risk
People allergic to plants in the Anacardiaceae family (poison ivy, mango) may experience a reaction.
Best for
- People looking for a gentle, natural antioxidant
- Those with sensitive or easily irritated skin who want extra protection
Use caution if
- Individuals with known allergies to sumac or related plants (e.g., poison ivy, mango)
- Those seeking a proven, high-efficacy antioxidant with strong clinical backing
Usage tips
Safety summary
Generally regarded as safe for topical use in cosmetics at typical concentrations. Rare allergic reactions may occur in individuals sensitive to the Anacardiaceae family. Always patch test if you have known plant allergies.
Research notes
Preliminary lab studies show antioxidant and anti-inflammatory activity, but clinical evidence on human skin is sparse. More research is needed to confirm its efficacy and optimal use in skincare.
Common label clues
- Typical concentration
- 0.1% to 2% in leave-on products
- Regulatory status
- Approved for cosmetic use in the EU, US, and most major markets as a botanical ingredient. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Serums, Moisturizers, Toning products
- Environmental note
- Staghorn sumac is a hardy, fast-growing plant often considered invasive in some regions. Sourcing from cultivated or wild-harvested populations can vary in sustainability.
Good to know
