This product has a unique texture; I like to apply it with a stiffer synthetic brush to pack it on, or a softer blending brush (like Mac’s 217 Blending Brush) for washes of color. Experiment with it until you find a brush companion that works best for you!
I love that so many brands are making “paints” for all types of products, encouraging the world to have some fun with their makeup and go for it. I am a true believer that you can pull off a look like this easily if you keep the rest of your face minimal. Try Make Up Forever’s Aqua XL Color Paint in shade M-72 Matte Red with a small pointed detail brush like Smith Cosmetics #202 Microliner Brush.
