Ingredient review
Tithonia Extract
INCI: Tithonia Diversifolia Flower/Leaf/Stem Extract
A gentle plant extract with antioxidant potential, but research is still early and benefits are not yet proven in human skin.
In plain English
Tithonia extract comes from the Mexican sunflower, a bright yellow flower. In skincare, it is used to help protect skin from environmental stress and calm minor irritation. Think of it as a mild helper ingredient that may support your skin's defenses, but it's not a powerhouse like vitamin C or niacinamide.

What it is
Tithonia Diversifolia is a flowering plant native to Mexico and Central America. The extract is made from its flowers, leaves, and stems, and contains natural compounds like flavonoids and sesquiterpene lactones that have antioxidant and anti-inflammatory properties.
How it works
The flavonoids in Tithonia extract can neutralize free radicals, which are unstable molecules that can damage skin cells. Its anti-inflammatory compounds may help reduce redness and calm irritation. In a formula, it works alongside other antioxidants to support overall skin health.
Pros
Natural antioxidant source
Contains flavonoids that can help protect skin from free radical damage caused by UV and pollution.
Gentle soothing potential
Early research suggests anti-inflammatory activity that may help calm mild redness or irritation.
Cons and cautions
Limited skin research
Most studies are lab-based or on animals; there are very few human trials confirming its benefits on skin.
Potential allergen for some
As a member of the Asteraceae family, it may cause contact dermatitis in people allergic to ragweed or daisies.
