Proactiv Refining Mask - How long do I keep it on?

How long do I keep it on if I use it as a mask?


Overnight, or for the 10 minutes as explained on the back?Proactiv Refining Mask - How long do I keep it on?
Until the mask is all dry and hardened. For me, it usually takes more than the 10 minutes. I leave it on for a good half an hour or so...





(45 minutes should do it for sure).
