Select the right sunscreen: Those with darker skin tones should go for micronised formulas. Use a formula that has a higher moisturising factor so the SPF has a chance to work.
Maintain the order: Apply the sunscreen after applying the moisturiser and other skin treatments but before make-up. If you’re not wearing makeup, it should be the last thing you apply on your skin.
Use it liberally: If you don’t apply an adequate amount, you won’t have a thick enough layer of sunscreen to form a shield for adequate protection.
Follow a motion: Pat on sunscreen (instead of rubbing it in) to get a uniform film of sunscreen and uniform protection too. Patting makes it easier to apply.
Wait for it to work: It is best to wait 20-30 minutes after application and before going out so the UV filters have time to soak into your skin and form a protective layer.
Re-apply through the day. Re-apply sunscreen every two hours, especially if you are going to be outdoors for a long time. Re-applying ensures that you get full protection.
