1) Lipstick. A swipe of lipstick on your lips creates an instantly more polished look. And lipstick will also work to bring color to your cheeks. You can use lipstick as you would a cream blush and blend it in with your finger.
2) Mascara. Grabbed the eyeliner brush but forgot the eyeliner? Mascara makes a great backup. Load up the eyeliner brush with mascara and apply as usual.
3) Foundation. If you’re working with only a few beauty products, a full face of foundation may be a little much. Instead, just embrace the fresh-faced look and use foundation as concealer to cover any imperfections. Quick tip: foundation that has collected on the cap or sides of the bottle tends to be a bit thicker – use that for better coverage.
