New Zealand has some of the highest UV levels in the world, and our clear air means you can burn quickly, even on cooler or cloudy days. Sunscreen is one part of good sun protection, alongside shade, hats, sunglasses and covering up - the classic slip, slop, slap and wrap.
How sunscreen works
Sunscreens protect skin from ultraviolet radiation: UVB, which mainly causes burning, and UVA, which penetrates deeper and contributes to skin ageing. Look for a product labelled broad spectrum, which means it covers both.
Mineral vs chemical sunscreen
Mineral (physical) sunscreens
- Primarily use zinc oxide as the sun-protective factor
- Sit on the skin's surface and reflect and scatter UV
- Work as soon as they're applied
- Often preferred for sensitive skin, children and anyone avoiding synthetic chemicals
Chemical (synthetic) sunscreens
- Use synthetic chemicals that absorb UV and convert it to heat
- Not reef-safe
Both types protect when used correctly, however many people who want a low-tox option will prefer mineral sunscreens, especially for daily wear and for kids.
What SPF50+ means
SPF measures protection from UVB. SPF50+ filters roughly 98% of UVB when applied at the tested amount. Most of us apply far less than that, so a generous layer matters more than chasing a higher number.
How to choose a natural sunscreen
- Broad spectrum, SPF50+ for New Zealand conditions
- Tested to the Australian/New Zealand standard (look for AS/NZS 2604 on the label)
- Zinc oxide as the active if you prefer mineral protection
- Nourishing ingredients that suit your skin type
- Water resistance if you're swimming or sweating

How to apply your sunblock properly
- Apply it 15–20 minutes before going outside.
- Use about a teaspoon for your face and neck, and a shot-glass amount for the body.
- Don't forget your ears, the back of the neck, feet and the parting in your hair.
- Reapply every two hours, and after swimming, towelling or heavy sweating.
- Keep it out of hot cars as heat can break down the formula making it less effective.
Sunscreen is only one part of sun safety
Careful and considered exposure is key! Especially between 10am and 4pm from September to April. Build your summer beach kit with our Soothe Skin Aloe Gel and Bug Repellent Spray.
