A common sense about sunscreen.
If you usually use sunscreen, you need to know no matter what brand, or how high the coefficients of SPF and PA,
As long as you don’t use enough amount = Nothing
Use sunscreen to your skin, you might think like this>>
Or something like this>>
But it’s actually like this>>
Because the surface of the skin is not smooth, all the liquid applied on it will not spread evenly on it but will flow down. The same applies to sunscreen. If you want to really make sunscreen work, you need to use this amount: 2mg/c㎡
So~do not skimp on your sunscreeen:)
