Intro: The Oompa Loompa Effect
You apply foundation.
It matches perfectly.
You look great.
Two hours later…
Orange.
This isn’t bad luck.
It’s chemistry.
What Oxidation Really Is
Oxidation happens when foundation ingredients react with:
oxygen
skin oils
sweat
heat
skin pH
This chemical reaction darkens pigments.
Why Iron Oxides Change Color
Most foundations use iron oxides for pigment.
Iron oxides are stable — but they react with oils on the skin.
More oil = more oxidation.
The Nut Oil Problem
Nut oils oxidize easily.
They:
break down in heat
react with pigments
accelerate color changes
Foundations with almond, argan, or shea are more likely to oxidize.
Why Oily & Sensitive Skin Oxidize Faster
Oily skin produces more lipids.
Sensitive skin often has barrier disruption.
Both increase chemical reactions on the skin.
How Modern Formulas Prevent Oxidation
Advanced formulations use:
silicone elastomers
stable esters
antioxidant systems
nut-free oils
Better chemistry = color stays true.
How to Prevent Oxidation
✔ choose nut-free foundations
✔ prep skin with lightweight hydration
✔ avoid heavy oils underneath makeup
✔ set gently
Final Thought
Orange foundation isn’t your fault.
It’s chemistry.
And good chemistry matters.
