Heat, sweat, and humidity - oh my! Summer can be tough on makeup, but your lip color doesn't have to suffer. My selection of the best summer lip shades is long-lasting, vibrant, and will survive even the hottest of days. First up, Swiss Beauty HD Matte Lipstick in 'Plum House.' This deep, rich plum shade is perfect for adding a touch of drama to any summer look. Plus, the matte finish is long-lasting and won't smudge or budge in the heat. For a more subdued look, try Plum Matte in Heaven Liquid Lipstick in 'Cocoa Mocha.' This warm, brown shade is perfect for a natural, everyday look. The liquid formula dries to a matte finish and won't transfer or fade, even after a day in the sun. If you're looking for a lip shade that will stay put all day long, look no further than Maybelline New York Super Stay Matte Ink Liquid Lipstick. This ultra-pigmented formula comes in a variety of shades, but we're loving the bold 'Voyager' for summer. Last but not least, we have PAC Timeless Matte Adore Lipstick in '6-5.' This bright, coral shade screams summer and is perfect for a day at the beach or a night out with friends. The creamy formula glides on smoothly and won't dry out your lips. So there you have it, four summer lip shades that are sure to turn heads. Which one will you be trying?
