Using this eyeshadow palette is a breeze. First, choose the color you like according to your makeup style. You can start with a light - colored base shade and then add darker shades for depth and gradient effect. Apply the eyeshadow with an eyeshadow brush, starting from the lash line and gradually blending upwards. For a shiny look, use the pearlescent shades. When it comes to maintenance, keep the palette in a cool and dry place. Avoid exposing it to direct sunlight or high humidity. After use, make sure to close the palette tightly to prevent the eyeshadows from drying out. Also, clean your eyeshadow brushes regularly to avoid cross - contamination. And always check the expiration date, as the shelf life of this palette is 36 months.
