Sunscreen dos and don'ts
Do learn how SPF works
Most experts agree that SPF 30 provides adequate sun protection. Higher SPF sunscreens aren't much better.
Use enough sunscreen to fully cover your skin, even if it feels sticky. Overestimate your needs.
Sunscreen loses effectiveness over time, and an expired bottle can cause a sunburn. Check the date before applying.
Check sunscreen's expiration date
Sun damage to the hands is easy to overlook when applying sunscreen. Consider a moisturiser with SPF for sun protection.
Chemical sunscreens convert the sun's rays into heat before releasing them from your body.
Physical and chemical sunscreens are different
Reapply sunscreen every two hours if you're swimming or active. Set an alarm on your phone to remind you when to reapply sunscreen.
Many brands offer non-comedogenic sunscreens for acne-prone or sensitive skin. La Roche Posay and CeraVe make gentle facial sunscreens.
Face sunscreens should be non-comedogenic.
