What it is
Cypress bark extract is a natural plant extract obtained from the bark of Cupressus sempervirens, the Mediterranean cypress. It contains tannins, flavonoids, and essential oils that give it astringent and antioxidant properties.
How it works
The tannins in cypress bark extract bind to proteins in the skin's outer layer, causing a mild tightening effect that can temporarily reduce the look of pores. Its flavonoids help neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging.
Pros
Natural astringent
Provides a gentle tightening effect that can help minimize the appearance of pores without the harshness of alcohol-based astringents.
Antioxidant support
Contains flavonoids that help protect skin from environmental stressors like pollution and UV damage, which can contribute to premature aging.
Cons and cautions
Limited evidence
Most of the supporting research is on the plant's general properties, not specifically on its effects in cosmetic formulations on human skin.
Potential sensitivity
While generally well-tolerated, the tannins and essential oil components may cause irritation or redness in some individuals, especially those with compromised skin barriers.
Best for
- People with oily or combination skin looking for pore-tightening benefits
- Those who prefer natural, plant-based skincare ingredients
Use caution if
- Individuals with very sensitive or reactive skin should patch test first
- Anyone with a known allergy to cypress or related plants
