5 surprising facts ABOUT YOUR SPF

surprising truth about sunscreen

WE ALL KNOW THE BASICS ABOUT SUNSCREEN…

… apply 15-30 minutes before sun exposure; wear daily to prevent premature ageing; reapply after swimming.


But there are some things you may not know, like the five facts below:

1. Makeup with SPF isn’t enough to protect your skin. To get the benefits of the SPF listed on the bottle, you need to apply one teaspoon for the exposed areas of your face and neck—way more foundation or powder than you’d ever need. Think of make-up with SPF as a supplement, but you should put on a good base of sunscreen every day.

2. You’ve got to reapply every two hours – no exceptions! One coat isn’t enough to protect your skin all day, whether you’re swimming or not. Even the best sunscreens need to be reapplied every two hours. If you’ll be out in the sun for long periods, set a reminder on your phone to re-apply.

3. Sunscreen is a must even when you’re indoors. Notice more freckling or discoloration on the left side of your face? That’s likely a result of UV rays penetrating through your driver’s side window. UV rays aren’t blocked by clouds or glass, which means you’ll need plenty of SPF even if you spend your days at a desk.

4. Chemical and mineral sunscreens are both effective, but work differently. Chemical sunscreens absorb the sun’s UV rays; mineral sunscreens block those rays. Both are FDA-approved, and experts agrees that chemical sunscreens are safe and effective. However, since many people now prefer natural formulations, mineral sunscreen is gaining popularity.

 5. Expired sunscreen can do more harm than good. Using an expired sunscreen can lead to reduced protection from UV rays due to diminished SPF. Plus, expired formulas can also contain bacteria and fungus growth (yuck!). Sunscreens degrade in hot temperatures, so those left in the glove compartment, for example, might lose their effectiveness well before the expiration date. No expiration date? Toss after one year.
