Radiation & skin
Radiation targets the cancer.
What it does to your skin is different.You're not overreacting to this. The burning. The tightness. Products you've used for years suddenly stinging. That's not ordinary dryness, and more moisturiser won't fix it. Here's why, and what actually will. The goal is skin that holds up through treatment, not just survives it.
What's happening
Your skin stopped producing its own oils.
Omega-7 (palmitoleic acid) in macadamia oil
Radiation damages the glands that make your skin's own oil.
Treatment damages the sebaceous glands in the radiation field. Without the fatty acid those glands produce, the barrier loses its ability to hold itself together. Macadamia oil contains 17-22% omega-7 (palmitoleic acid), the same fatty acid your skin produces naturally.
Mac Pure is also used by people recovering from cosmetic skin treatments including micro-needling, laser resurfacing, and chemical peels, where the skin barrier experiences similar disruption.

Your skin already knows this oil.
Macadamia oil is one of the richest plant sources of omega-7 (palmitoleic acid). Unlike sea buckthorn, it's skin-tone neutral and absorbs cleanly, making it the only practical choice for a daily leave-on formulation. It's the same fatty acid found naturally in the oil your skin produces itself. When radiation stops that production, macadamia oil replenishes exactly what the barrier has lost. Not a coating on the surface. A structural match for what was there.

Barrier replacement
Integrates into the barrier structure, not just the surface
My radiation nurses kept asking what I was using because my skin didn't look as raw as the other patients. My skin didn't crack or break in those seven weeks either. Mac Pure was the only thing that worked for me.
