What it is
Juniperus virginiana oil is an essential oil obtained from the wood of the eastern red cedar tree, rich in sesquiterpene compounds such as cedrol and cedrenes that give its characteristic warm, woody scent. In cosmetics it is used mainly to fragrance or mask odors in a formula. In sunscreens it is a scent ingredient and has no role in UV protection.
Safety & warnings
As a natural essential oil, cedarwood oil is a fragrance material that can cause irritation or allergic contact dermatitis in sensitive individuals, and fragrance components are a common cause of cosmetic sensitization. People with fragrance sensitivity may prefer fragrance-free options. Oxidized essential oils tend to be more sensitizing, so formula freshness and antioxidant protection matter.
