What it is
An extract derived from the leaves and stems of Calocedrus decurrens, also known as incense cedar. It contains natural compounds like flavonoids and essential oils that give it antioxidant and anti-inflammatory properties.
How it works
The extract provides antioxidants that neutralize free radicals (unstable molecules that can damage skin cells). It also has mild anti-inflammatory effects that may help reduce redness and soothe sensitive skin. In a formula, it works alongside other ingredients to support overall skin health.
Pros
Gentle antioxidant
Provides free-radical protection without the irritation that some stronger antioxidants can cause, making it suitable for sensitive skin.
Soothing potential
May help calm redness and irritation, offering a dual benefit of protection and comfort in one ingredient.
Cons and cautions
Limited research
Most evidence comes from traditional use and lab studies, not large-scale human trials, so its effectiveness is not as well-documented as more studied antioxidants.
Rare allergy risk
As a plant extract, it can cause allergic reactions in people sensitive to cedar or conifer species, though this is uncommon.
Best for
- Anyone looking for a gentle, natural antioxidant in their routine
- People with normal to combination skin who want extra environmental protection
Use caution if
- Those with known allergies to cedar or conifer plants should patch test first
