Sunscreen before or after moisturizer?
I’ve updated my earlier entry Tips on sunscreen protection & application with a couple more information. One of which is about when to apply sunscreen in the order of our skincare regime because I noticed that this is something frequently asked.
Actually I’ve always thought that sunscreen should be applied after using our serums or moisturizer but if you consider that chemical sunscreens absorb UV rays and neutralize them in the skin tissues, then it make perfect sense that they should go on clean, bare skin first because in order to be effective, it must interact with our skin cells.
On the other hand, physical sunscreens containing titanium dioxide or zinc oxide to reflect or scatter UV radiation can be applied last, after a serum or moisturizer.
Well, sure sounds clear cut enough except that this still begs other questions.
Namely, how can serums be effective if they are applied after using a chemical sunscreen? In addition, what about those sunscreens that contain both chemical and physical ingredients like mexoryl and titanium dioxide? Are all-in-one sunscreens with moisturizer a better option then?
I never knew there was so much to be learnt about sunscreens. It’s certainly enlightening, but at the same time, rather frustrating if you know what I mean.
