Ingredients & Safety
Our Approach to Ingredients
Every ThermaSun product uses zinc oxide as the sole active UV filter — a naturally occurring mineral that sits on the skin's surface to physically block UV radiation. We don't use any chemical UV filters, synthetic absorbers, or the 12 chemical ingredients that the US FDA has flagged for further safety review.
Our zinc oxide is ZinClear® XP, manufactured by Advance ZincTek (ASX: ANO) in Queensland, Australia. It's pharmaceutical-grade, non-nano (200–700nm particle size), GMP manufactured, and ECOCERT COSMOS approved.

The FDA Position on UV Filters
In September 2021, the US FDA published its comprehensive sunscreen safety review. Of the 16 commonly used UV filters, only zinc oxide and titanium dioxide were recognised as Generally Recognised As Safe and Effective (GRASE). The remaining 12 chemical UV filters were classified as requiring further safety data. ThermaSun uses only zinc oxide — the gold standard.
