In all my research online, I have not come across the answer to this. I'm thrilled to see that my number of readers is going up each week, so I am hoping that one of my readers knows the answer to this.
Traditional sunscreen is effective for no more than 2 hours, less if you are more active.
I use sunscreen with a SPF 30 before leaving the house each day.
My every day body lotion has a SPF 15.
My morning facial moisturizer has a SPF 35
Depending on which foundation I use that day, it either has no SPF, SPF 15, or SPF 30.
If I were only to use the sunscreen in my body lotion, facial moisturizer and make up, as many people do, how long is that really effective for? I always think it is good for added protection, but sometimes think it also gives a false sense of security for long term or all day protection.
