Sun protection doesn't "stack"

Iโve had some really great feedback on my โposts- so I decided to share another tip today! โฃ

Letโs say youโre using a facial sunscreen with SPF 50, and then use a foundation/tinted moisturizer on top that also has SPF 50, you donโt then have SPF 100 protection! โฃ
In fact, you likely only have SPF 50 protection! โฃ
Why? Most of us donโt actually apply enough sunscreen in the first place. So, by using multiple layers that each offer protection, we are just building up the protection in areas we may have missed or not applied enough product with the initial layer! Its also very likely that when you add a second layer, you disturb the first layer and make up for this during the second application!โฃ
When it comes to SPF level, a recent study confirmed that higher SPF is actually more beneficial- again, because most of us donโt apply enough product! So, if you have the choice between SPF 50 or SPF 100- go for the SPF 100 and youโll likely achieve the protection of an SPF 50! (doi: 10.1016/j.jaad.2017.12.062โฃ)
