DIY- MATTE LIPSTICK Use flour, cornstarch, or even powdered sugar, pretty much any white powder would work. [DO NOT use baking soda]The white powder will go unseen even in the darkest shades of lipstick. Put on your lipstick as usual. Press the tip of your finger into the powder, shake or blow off any excess powder, you want a thin layer on your finger. Dab the powder onto your lipstick and press your lips together to make the powder absorb into your lipstick but DO NOT rub your lips together.
