Tired of wearing more lipstick on your teeth than your pout? Frustrated when your beautiful gloss pulls a disappearing act post-application? Well, you can now put an end to the senseless wasting of otherwise good lip color with Tarte's Seal the Deal ($18; sephora.com). Fashioned similarly to the brand's color glosses, with a separate wand on each side, this superstick is part sealant, part gloss, and all business. The colorless sealant goes on light to keep lipstick in line, preventing the infuriating bleeding and cracking that makes color go terribly, terribly awry. Just brush it lightly over your color for serious stay-put power, and follow with the supergloss, which adds a minty kick of sexy shine without the sticky, tacky, or dry aftermath. The result is a set of glistening, sultry lips that stay gorgeous throughout the day, making Seal the Deal one of the most reliable things in a girl's handbag this fall and, just maybe, in her life. --Janelle Harris
