How to Make Oil Serums
For Body, Face & Hair
An oil serum is a blend of carrier oils, active oils, and sometimes essential oils designed to nourish and treat skin or hair. Unlike solid balms, oil serums are 100% liquid and absorb directly into the skin without any wax barrier. Oil serums can target specific concerns like aging, dryness, acne, or dull hair, making them highly customizable for individual needs.
