High-performance zinc sunscreen for active Australians. 25% non-nano zinc oxide, SPF 50, water resistant to 80 minutes, sweat resistant — and because it’s zinc only, it won’t sting your eyes.
Zinc that stays put when you swim, run and sweat

How to use for training and racing

Frequently asked questions
What sunscreen won't sting my eyes when I swim or run?
Zinc-only mineral sunscreens like ThermaSun Sport Pro are far less likely to sting eyes than chemical sunscreens, because there are no chemical UV filters to run into the eyes as you sweat. It's SPF 50, water resistant to 80 minutes, with an anti-perspirant blend for sport.
Is it reef safe for surfing and snorkelling?
Yes. Sport Pro is a zinc-only formula with no oxybenzone or octinoxate, the chemicals most associated with coral harm, so it's a reef-safe choice for surfers, swimmers and snorkellers.
How often should I reapply when swimming?
Reapply at least every 2 hours, and always after 80 minutes in the water or after towel-drying. Water resistance is tested to 80 minutes, after which protection drops, so reapplication matters most during long water sessions.
What is the Natural White Sapphire anti-perspirant for?
It helps the sunscreen film resist being washed away by heavy sweat during intense exercise, so the protection holds up better through a full training session or race.
Is it really SPF50?
Sport Pro is TGA listed (AUST L 525639) and batch SPF tested on every production run, so each batch is verified to its labelled SPF.
Why you can trust the zinc in ThermaSun
ThermaSun is built on ZinClear® XP — a pharmaceutical/cosmetic-grade, non-nano zinc oxide whose underlying technology was originally developed by researchers at the University of Western Australia and commercialised by Advance ZincTek (ASX:ANO), an Australian company formed in 1997. It’s the same Australian-made mineral active trusted by dozens of skincare brands worldwide.
Every ThermaSun sunscreen is then made in Queensland by VeganicSKN, is TGA listed (with its AUST L number printed on the pack and searchable on the ARTG), and is batch SPF tested on every production run. Zinc oxide is the broad-spectrum mineral UV filter the TGA recognises, and our zinc-only formulas contain no oxybenzone or octinoxate, so they’re reef safe.
ThermaSun is Australian made in Queensland by VeganicSKN. Always read the label and use only as directed. Sunscreen is one part of sun protection — combine with shade, clothing, a hat and sunglasses. Reapply at least every 2 hours and after swimming, sweating or towelling.
