OK

pu3. You can see if it's good for sun protection through pa, and spf lasts for a long time, but it's good to apply it every 2 hours anyway, so 15 is enough

OK

pu4. SKY

OK

pu6. Spf means that the higher the number, the longer the duration
Pa means that the more +, the better the blocking effect

OK

pu7. In theory, spf15 is every 2 hours, but I'm told to apply it every 2 hours anyway, so 37 is enough
