Using moisturizers with SPF
Am I protected if my moisturiser has spf and then I apply a foundation that does not have spf? Does applying non spf skincare or makeup over the spf moisturiser dilute the effectiveness of the spf moisturiser?
You are protected and are doing it properly. Apply moisturizer with SPF first, allow it to “set” for a moment and then apply your non-SPF skincare or makeup over the SPF moisturizer. As long as you have allowed the first product with SPF to “set”, subsequently applied skincare products should not affect the sun protection of the first product.
