Ingredient review
Tibouchina Extract
INCI: Tibouchina Lepidota Bark/Flower/Leaf Extract
A gentle, plant-derived antioxidant that may help protect skin from environmental stress, though research is still emerging.
In plain English
Tibouchina extract comes from the bark, flowers, and leaves of the Tibouchina lepidota plant, also known as the princess flower. In skincare, it's used for its antioxidant properties, meaning it can help neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. Think of it as a shield that helps your skin cope with pollution and UV exposure, though it's not a substitute for sunscreen. It's generally very gentle and suitable for most skin types.

What it is
A natural extract derived from the bark, flowers, and leaves of the Tibouchina lepidota plant, a flowering shrub native to South America. It contains polyphenols and flavonoids, which are compounds known for their antioxidant and anti-inflammatory effects.
How it works
The polyphenols in Tibouchina extract donate electrons to neutralize free radicals, preventing them from causing oxidative stress in skin cells. This helps reduce inflammation and supports the skin's natural repair processes. In a formula, it also contributes to the product's overall stability by protecting other ingredients from oxidation.
Pros
Gentle antioxidant
Provides free-radical protection without common irritation, making it suitable for sensitive skin.
Multi-part plant source
Uses bark, flowers, and leaves, which may offer a broader range of beneficial compounds than single-part extracts.
Cons and cautions
Limited research
Most evidence comes from lab studies; there are few human clinical trials confirming its effectiveness in skincare.
Potential allergen
As a botanical extract, it can cause allergic reactions in rare cases, especially in those with plant allergies.
Best for
- Anyone looking to boost their skincare routine's antioxidant defenses
- Those with normal to combination skin seeking a gentle, plant-based ingredient
Use caution if
- Individuals with known allergies to Tibouchina or related plant species
