Applying Proactive Refining mask to pimple during day?

I have a pimple with a little white head showing, but it needs more time for it to come out completely...When I leave the refining mask on overnight, the whitehead usually comes out....So can I leave it on during the day with the same effect?? I want to pop it tonight so I need it to come to a head. thanks!|||Yes you can leave it on during the day and it will have the same effect.
