People ask "does make-up with sunscreen really protect you from the sun?" The answer is, "yes."
[Dr. Schultz holds up a bottle of foundation.] This is age-defying make-up with an SPF of 20, soft beige for normal and combination skin. You actually will get an SPF 20 from this product, but there is only one catch: you have to make sure that it is the first thing you put on your skin after you have washed your face. The problem is women wear many other products than make-up and sunscreen. They wear moisturizers, exfoliants, and some of them use acne and blemish products. If you are going to put this product on first as you need to, to get the SPF protection, and you then put your other products on top of it, the other products may either mess up your make-up or the other products may not work properly on top of this foundation.
The take-away is make-up with sunscreen is effective and very convenient, but if you need to use other products at the same time I think you'll be back using regular sunscreen first, your other products next, and then your regular foundation on top.
