Overview
Cypress adds scent, not firmness or skin feel. Its dry, green conifer note can make heavy leather, resin, tobacco, smoky, or sweet blends smell brighter and less dense.
There is no single amount that fits every oil and product. Check the supplier's current usage and allergen guidance and the International Fragrance Association (IFRA) guidance for the exact product type, then adjust only through small test batches. Add it after the base begins to cool, because heat and air can dull the brighter scent.
