## Who should consider it?

Choose a sunscreen by the label, how it feels at the required application amount, and how readily you will reapply it. Test the tint in daylight; two flexible options will not look identical on every skin tone.

## What should you check before buying?

Do not add SPF numbers together when layering products. If swimming or sweating is part of the day, check the exact bottle’s water-resistance directions and select protection appropriate to that activity.

## How to use it

1. Apply the amount and timing specified on the local sunscreen label.
2. Let the sunscreen settle before adding makeup.
3. Reapply as directed, including during extended outdoor exposure.
