@bykristinanguyen: Testing the 2-hour sunscreen rule with @ROUND LAB! Keep in mind, different weather and activities can affect results but for today’s test, the weather was partly cloudy in 4°C Canadian winter!! #roundlab #sunscreen #uvprotection #koreanskincare
2h rule is for physical sunscreen. You are using chemical one, you are gonna irritate your skin if you apply every 2 hour.

when you reapply sunscreen, did y'all wash your face before applying sunscreen or apply it directly even if you haven't washed your face yet?

i think the 2h rule really makes sense when going to the beach or pools where it can get removed very easily, but for everyday its more like a "lets sell more" thing

Uv cameras don’t show the spf, it just shows how evenly you’ve applied your sunscreen. It could be spf 15 by the time it’s night. Please don’t spread misinformation.

I saw a study saying that reapplication isn’t always necessary unless your activities include possibly rubbing/washing off the sunscreen

I think the 2h rule applies mostly when you’re outside in the sun… if you’re inside or in partial shade it’s not needed. Generally I apply it in the morning and before leaving work

I've read a study the other day about the sunscreens but I can't find it again 😭 It was a canadian study though because it was talking about the cancer rate of Canada. The study said that unless you wanted to go swimming, applying sunscreen just right before going was working and that 2 hours reapplication was not needed unless swimming, sweating or being in contact with exfiolating substance like sand.

how much n how often you should reapply depends on the uv index. Just check ur weather app daily to know the uv index. also you can use sunscreen cream thick in the morning n use sticks to reapply over the day
