12 Crucial Mistakes You're Making With Sunscreen And How To Fix Them

5. Reapplication: The Two-Hour Rule

Sunscreen is not a one-time application. Its effectiveness diminishes over time, especially with exposure to water, sweat, and friction. Experts recommend reapplying every two hours, or immediately after swimming or sweating. This ensures continuous protection throughout the day. Many people neglect this crucial step, leading to unexpected sunburns and increased skin damage. By making reapplication a routine part of your sun protection strategy, you can maintain consistent defense against harmful UV rays, transforming a frequent oversight into a proactive habit.
