What it is
An extract derived from the young buds of the Cryptomeria japonica tree, native to Japan. It contains compounds like flavonoids and terpenoids that have antioxidant and anti-inflammatory activity.
How it works
The extract provides antioxidant compounds that neutralize free radicals generated by UV rays and pollution. It also may calm redness by reducing the activity of inflammatory messengers in the skin, helping to maintain a balanced, comfortable complexion.
Pros
Gentle antioxidant
Helps protect skin from free radical damage without irritation, making it suitable for daily use in serums or moisturizers.
Soothing potential
May reduce redness and calm sensitive skin, offering a mild anti-inflammatory effect for reactive complexions.
Cons and cautions
Limited research
Most evidence comes from lab studies, not large human trials, so its real-world benefits are less certain than more studied antioxidants like vitamin C.
Allergy risk
As a plant extract, it can cause contact dermatitis in rare cases, especially in those allergic to tree pollens or conifers.
Best for
- Anyone looking for a gentle antioxidant boost
- Those with normal to oily skin who want a lightweight, non-greasy ingredient
Use caution if
- Individuals with known allergies to cedar or conifer plants should patch test first
