3 seconds. Up to 36 hours of wear. Listen... if I took the time to do my makeup, I want it staying exactly where I put it, and especially as a busy mom! I'm loving this 3-Second Setting Mist and I can already tell this is going to be the one I reach for when I need my makeup LOCKED IN. The mist is so fine, it doesn't leave me feeling sticky, and for a drugstore price? She might be a little overachiever. Because sometimes I want luxury results without the luxury receipt.
