Pro Tips for Sunscreen Amount
- A full-body application commonly recommended is about 30 mL (roughly a shot glass full) per adult per application — many people apply significantly less than this in practice.
- Reapplication every 2 hours (or after swimming/sweating) is commonly recommended regardless of SPF rating, so plan applications-per-person accordingly for a full day.
Common Sunscreen Amount Mistakes to Avoid
- Using a much smaller amount-per-application than the commonly recommended full-body dose, which is a common reason sunscreen provides less protection than its labeled SPF suggests in practice.
