Macadamia Oil – Benefits, Side Effects & Uses

by ThankMeNow Editors on Sep 10, 2025
Macadamia Oil is a unique biological standout in the botanical world due to its exceptionally high concentration of Palmitoleic Acid (Omega-7). While most plant oils are rich in Omega-6 or Omega-9, Macadamia is one of the few concentrated plant sources of Omega-7—a fatty acid that is a natural component of human sebum but decreases significantly as we age. This makes it a "bio-mimetic" replenisher that helps "fill in the gaps" of a maturing or depleted barrier. Its structure allows it to provide a non-greasy, velvet-like finish that feels more like a second skin than a heavy oil coating.
