To use this eyeshadow palette, start by choosing a light - colored shade as a base and apply it all over your eyelid. Then, pick a darker shade for the crease to add depth. You can use a brush or your finger to apply the eyeshadow. When using a brush, make sure to tap off any excess powder before applying it to your eyes. Remember to close the palette tightly after use to keep the eyeshadows fresh. Also, avoid getting the eyeshadows wet as it can affect their quality. If you want to clean your brushes, do it regularly to prevent color mixing and ensure smooth application.
