The best time to apply sunscreen is before going outside.
According to Zeichner, applying sunscreen before exposure to the sun is most effective because there are fewer distractions, allowing you to ensure all exposed areas of skin are adequately covered. This proactive approach is critical to maximizing the sunscreen's protective capabilities.
Here’s a breakdown of why applying sunscreen beforehand is beneficial:
- Thorough Coverage: When you apply sunscreen inside, you have more time to ensure you’ve reached all exposed areas. This includes often-missed spots like:
- Ears
- Back of the neck
- Tops of feet
- Scalp, if hair is thinning or parted
- Reduced Distractions: Applying sunscreen indoors, away from the distractions of being outside (like children, pets, or wanting to start an activity), allows for better focus, promoting more comprehensive and even coverage.
- Optimal Absorption: Sunscreens typically need about 15-30 minutes to fully absorb into the skin and form a protective barrier. Applying beforehand gives the sunscreen adequate time to become effective before sun exposure.
How to Apply Sunscreen Effectively
To maximize your sunscreen’s protective power, keep these tips in mind:
- Choose the Right SPF: Select a sunscreen with an SPF (Sun Protection Factor) of 30 or higher for optimal protection against both UVA and UVB rays.
- Apply Generously: Use about an ounce (a shot glass full) of sunscreen to cover your entire body. Don’t skimp.
- Reapply Often: Reapply sunscreen every two hours, or immediately after swimming or sweating.
