I believe so. Sunscreens must be applied 30 minutes before going out and must be reapplied every 1-2 hours. I saw a japanese video in the past (couldn't find it now because it is not on youtube) where they show how to correctly apply sunscreen. According to that video, it shouldn't be rubbed into your skin but just pat it to spread it evenly.
