在新加坡防晒一定要spf 50 +
我以前一直这么认为， 后来看一个皮肤科医生写的东西， 感觉Spf 25就够了
Spf 15 (with complete UVA protection or PA+++)............for regular indoor and brief outdoor use.
Spf 30 (with complete UVA protection or PA+++)............for indoor or outdoor use.
everything over spf 30 ....doesn't really mean much.....for example spf30 protect you 97.5% of uv ray while spf 50 protect you 98% NO BIG DEAL.
spf20 + spf 10 though will give you a little bit more protection, they WILL NOT give you spf 30.....
