Why is SPF so important? - the facts #1

Lets Talk SPF

SPF is a game changer, it is something I cannot live without. However, the habit of using an SPF on the daily can be somewhat of a tricky one to get a hold of. So here are some of the facts that might help you change the way you think about SPF's. 


One of the most common phrases we have all heard, is to apply a high SPF twenty to thirty minutes before sun exposure, to reapply after swimming, wear it daily to prevent premature ageing and what about last year's sunscreen? Can we still use it? I have become increasingly aware that some people only relate SPF's to summer holidays. They do not even consider wearing it everyday and making it apart of their routine. Tinted moisturisers with SPF have also become increasingly popular, but is that even enough? Did you also know you should even wear it indoors? No, I didn't either, until recently. 

I've been doing some research of my own, here are five facts I came across on the BirchBox website.
(1) BirchBox, "Safe Sun: 5 Surprising facts about SFP." - https://www.birchbox.com/magazine/article/safe-sun-5-surprising-facts-about-spf


1. Expired sunscreen can do more harm than good

“Using an expired sunscreen can lead to reduced protection from UV rays due to diminished SPF,” says Holly Thaggard, Founder and CEO of Supergoop!. Plus, Thaggard says, expired formulas can also contain bacteria and fungus growth (yuck!). Elizabeth Hale, M.D., board certified dermatologist and a Clinical Associate Professor of Dermatology at New York University Langone Medical Center, adds, “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.

2. 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,” Dr. Hale says. Thaggard’s memory trick? “If you’ll be out in the sun for long periods, set a reminder on your phone to reapply.”

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 Dr. Hale agrees that chemical sunscreens are safe and effective. However, since many consumers now prefer natural formulations, mineral sunscreen is gaining popularity.

5. 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. Dr. Hale says, “I tell patients those are nice as supplements, but you should put on a good base of sunscreen every day.”

I have more SPF facts that I am going to be sharing with you throughout the next few weeks of summer, so make sure you are following me on Bloglovin if you want to be kept in the loop.
What are your opinions of SPF, is it in your daily routine? I sure hope so!..
