How do I apply this acne cream on my skin?

I was prescribed ';Tretinoin'; 0.025%


It says ';Apply to the effected area before bedtime';





When it says ';effected'; does it mean the whole face, or just the zits?





Also, when I apply it, do I leave the cream to a visible ';WHITE'; color or keep on rubbing until the white is gone?How do I apply this acne cream on my skin?
Affected area means any area with pimples, so yes, apply it directly to the zits. Also, try to rub it in until it disappears from your view.How do I apply this acne cream on my skin?
