There are several ways to make your nail polish matte. Here are some of them:

1. Steam method: Paint your nails as you normally would and then heat up a pan of water (no need for a large pan). Once you have some steam, place your hand over it for 3-5 seconds .

2. Cornstarch method: Pour the white nail polish into a bowl. Then, use a spoon to mix in a small amount of cornstarch until the polish becomes matte. Apply the polish to your nails and enjoy your new, matte white nail polish!

3. Powder method: Mix your nail polish with baby powder or cornstarch. Apply the mixture to your nails and let it dry completely before applying a topcoat.
