I know you will say no. Then why does the bottle say wait 30 minutes before going outside after applying the sunscreen. Is it to absorb the oils, and if it is, does that mean the zinc oxide isn't working right away. What do you think about this?
Hi MV, I don't know of any sunblocks that say you have to wait 30 minutes. The only products that I have seen that use the warning is for sunscreens using a chemical sunscreen and not a physical block. Physical blocks work immediately, but I can imagine some manufacturers snagging the warning or using the time frame to help disperse the ZnO.
