Using this eye color palette is super easy. First, pick the shade you like. Dip your eyeshadow brush into the powder gently and tap off any excess. Then, apply it to your eyelid in a smooth motion. You can start with a light - colored base shade all over the lid and then add darker shades in the crease for depth. For a more intense look, you can wet your brush before dipping it into the powder. When it comes to maintenance, keep the palette in a cool, dry place to prevent the powder from drying out or getting clumpy. Close the lid tightly after each use. Also, be careful not to get water or other liquids inside the palette. And always remember to wash your makeup brushes regularly to avoid any bacteria build - up. If you have sensitive skin, it's a good idea to do a patch test on your wrist first to make sure you don't have an allergic reaction to the ingredients.
