Benzene in Skincare, Explained — And Why We List All 15 Ingredients
Share
Benzene's been in the skincare headlines lately. Here's the honest version — and what it means for what you put on your skin.
If you've seen "benzene" and "skincare" in the same sentence recently and felt a bit uneasy, you're not alone. It's a scary word — benzene is a known carcinogen — so it's worth understanding what's actually being talked about, without the panic.
What's actually going on
The concern centres on benzoyl peroxide — a common active ingredient in acne treatments. Research from an independent lab in 2024 found that benzoyl peroxide can break down and form benzene over time, especially when products are stored somewhere warm (think a steamy bathroom or a hot car).
It's important to be fair about where this landed: when the regulator (the FDA) tested a wide range of these products, the large majority showed undetectable or very low levels of benzene, and only a small number were recalled. The science is still being debated. But the headline takeaway is reasonable enough: some active ingredients can degrade into things you didn't sign up for.
Two things worth knowing:
- This was about acne products with benzoyl peroxide — not moisturisers.
- Benzene wasn't an ingredient anyone added. It's a by-product of an ingredient breaking down.
The real lesson: know what's in the bottle
You shouldn't need a chemistry degree to understand your moisturiser. The more ingredients on a label — and the more of them you can't pronounce — the harder it is to know what's actually going on in there, and what might happen to it over months on your shelf.
That's the whole reason Koa Shore exists.
Why we keep it to 15
Daily Defence has fifteen ingredients. That's it — and every one is printed on the bottle.
- Two heroes: grass-fed tallow (sourced from New Zealand) and non-nano zinc oxide
- Three supporting: MCT oil, vitamin E, olive oil
- The technical bits: water, a plant-derived emulsifier system and a coconut-derived preservative — the chemistry that keeps an emulsion stable, nothing hidden
No benzoyl peroxide. No synthetic fragrance base. No long tail of mystery actives. We list all of them — not just the ones we'd like to talk about — because you deserve to know exactly what you're putting on your skin every morning.
Simple isn't a marketing angle for us. It's the point.
Made small, made here
Daily Defence is made in Australia in small batches, with grass-fed tallow from New Zealand. Small batches mean we can actually stand behind every bottle.
