If you are at work and just walking around then using a hat is another good idea that will help your sun protection. It is good to be mindful of how much protection you get from sunscreen itself, and their limits also. Physical sunscreens with micronized particlets need to be coated with dimethicone to be sure that they don't break down with UV. Chemical sunscreens may also break down or cause other reactions. Here is another article about micro zinc oxide sunscreens that shows that even physical sunscreens require some care. http://rosacea-support.org/micronized-zinc-oxide-dimethicone-safe.html Hi Louise, I think you only need to reapply sunscreen if you are outside and are sweating or in the water.

It's great advice to tell us to reapply every two hours, but not particularly practical for people who wear makeup. Even someone working in an office setting is going to be exposed to the sun on the way to work, at lunch time and after work (in summer anyway), and I doubt those people will be washing off their foundation in order to reapply sunscreen before leaving for lunch, and then again before leaving work at the end of the day.
