Frequently Asked Questions ❓
How long before snorkelling should I apply reef-safe sunscreen?
You should apply sunscreen at least 15 to 20 minutes before entering the water. This allows the product to form an even protective layer on your skin and improves its effectiveness.
Is a rash vest better than relying only on sunscreen?
Yes. A rash vest provides physical sun protection and reduces the amount of sunscreen you need to apply. Many experienced snorkellers use both for maximum protection.
Do reef-safe sunscreens expire?
Yes. Sunscreens lose effectiveness over time. Always check the expiry date before your trip and replace any product that has expired.
Can reef-safe sunscreen prevent sunburn completely?
No sunscreen can guarantee complete protection. Proper application, regular reapplication, protective clothing, and limiting exposure during peak UV hours all contribute to preventing sunburn.
Are reef-safe sunscreens suitable for everyday use?
Absolutely. Many reef-safe sunscreens work well for daily activities such as walking, hiking, swimming, and general outdoor use, making them a practical choice even when you’re not visiting the reef.
