MG Naturals · Evidence-based resource
Why does MG Naturals refuse to formulate with titanium dioxide?
Quick answer
Because the peer-reviewed evidence on photocatalytic free-radical generation, DNA damage in lab and animal studies, and the EU's 2022 food ban convinced our founder that the ingredient does not belong in products designed for daily use on facial skin — particularly for sensitive skin, compromised barriers, and children. Going TiO₂-free is the single biggest formulation choice we have made, and the most expensive one.
We didn't build the brand around titanium dioxide and then quietly remove it for marketing.
We refused to start with it.
The moment everything changed
Our original formulas had titanium dioxide in them. They were almost ready to launch.
Then a passing comment in a lecture stopped me cold. One of those throwaway lines that turns out not to be throwaway at all. I went home, pulled my formulation notes apart, and looked properly at what I'd been building.
I couldn't unsee it. So I started again.
That meant binning months of work. Reformulating from scratch. Sourcing different pigments. More testing. More expense. A harder, slower path to launch.
I chose it because I was never going to put my name on something I wouldn't put on my daughters' skin.

What this choice actually costs
Going titanium dioxide-free is not a labelling decision. It changes how every formula in the range has to be built.
Going titanium dioxide-free means
- More complex pigment systems
- Harder shade matching
- Longer R&D cycles
- Higher ingredient costs
- More batch-to-batch consistency work
- Less of the "instant blank canvas" finish customers have been trained to want
We do all of it. Every single time.
Because that's the brand.
Sensitive skin changes the standard
MG Naturals exists for people whose skin doesn't tolerate "probably fine." Reactive skin, compromised barriers, daily wearers, sensitive teens, mums buying for daughters with eczema. For these people, "industry standard" still feels heavy, irritating, or wrong.
A foundation built on titanium dioxide can end up contributing to the very thing it is meant to be covering.
We didn't want to participate in that loop. So we stepped out of it.
Peer-reviewed evidence
What we know — and what stays unanswered
Most studies on healthy, intact skin show TiO₂ particles stay in the outer layer and don't penetrate to deeper, living cells in any meaningful way. We say that plainly, because it's true, and because a library that only reports the findings that suit us isn't a library.
Here is where it gets uncomfortable. Compromised skin — eczema, dermatitis, post-procedure, micro-abrasions — behaves differently. And facial skin is more absorbent than most other sites on the body.
The "doesn't penetrate intact skin" line assumes everyone has perfect, intact skin every day. People with rosacea, eczema, sensitive skin, freshly exfoliated skin, or children with thinner barriers don't.

If an ingredient raises enough questions, and we can formulate beautifully without it, we take the harder path. Every time.
Titanium dioxide-free isn't a feature on our list. It's the line we won't cross.
