Sebum is the body's natural oil produced by the sebaceous gland. Hormonal imbalance causes the sebum secretion to go up or down. This causes our skin to become oily or dry.
Our blends here are created to balance the sebum secretion, hence are suitable for all skin types. The magic here is that the oils have the ability to understand the phenomenon which is called the human body and work with it to create balance. Nature!
