Lifting up downturned lips is much easier than you may think, even if you don't have concealer on hand. According to Her World, any highlighter will do the trick as well. To lift up your corners, you should start by applying your highlighter on both sides of your mouth to make your upper lip's shadow virtually disappear. Next, you'll need a liner that matches your natural lip color. Using a true-to-you shade, draw inside your lip line, filling it in with liner or lipstick, and voilà!

Once your lips are contoured into an upturned shape, you can use a gloss at the center for a pouty, just-bitten look (via Byrdie). That being said, if you've already overlined your lips to make them look fuller, a gloss might do more harm than good. All-over glosses deflect light from your top lip, creating a thinner effect, so just using it in the center is key. Oh, and remember to blend everything in for a seamless look!
