A few of Lisa’s Makeup Tips

Here are a few tips for using the makeup you already have in your makeup bag.

• Mix your old foundation with your new foundation
• Scoop your old concealer into a little pot and mix it with some moisturizer. You can mix the new concealer with it too.
• Dry makeup will last a long time and is safe as long as you are using clean brushes.
• Wet your brush and use your eyeshadow as an eyeliner.
• Line your entire lip with a lip liner to make your lips appear bigger, and use a tinted lip balm
