What Is Calocedrus Decurrens Leaf/Stem Extract?
Calocedrus Decurrens Leaf/Stem Extract is a plant-based ingredient derived from the leaves and stems of the incense cedar, a conifer native to the western United States. The tree’s aromatic foliage contains a mix of volatile oils, terpenes, and phenolic compounds that give the extract its skin friendly profile. Indigenous communities valued incense cedar for its fragrant wood and soothing foliage long before modern formulators took notice. Interest from the cosmetics world grew as brands searched for botanical alternatives to synthetic conditioning agents.
To create the extract leaves and small stems are harvested, dried, then subjected to gentle solvent or supercritical CO2 extraction. The process concentrates the beneficial molecules while removing excess resin and wax. The resulting liquid or powdered extract is filtered and standardized so each batch delivers consistent performance in a formula.
You will most often see Calocedrus Decurrens Leaf/Stem Extract listed on the back of moisturizers, soothing masks, after-sun gels, lightweight lotions, anti-aging serums and even beard oils where its conditioning touch helps soften both skin and hair.

Comedogenic Rating
Rating: 1 / 5

Its quick-absorbing nature and minimal residue mean it rarely traps debris inside follicles. For this reason it is generally considered suitable for people who are prone to acne or breakouts.
As with any botanical, the final comedogenicity of a finished product depends on the other ingredients and the overall formula so always check the full ingredient list if congestion is a concern.
