I usually use a tinted moisturizer, but if you don't have any of that, any moisturizer or light lotion works well for me. You could also try dabbing on some light eye shadow that matches your skin tone.What do I use in place of an under-eye concealer?
Use bare minerals and take the foundation with a concealer brush and put it under your eyes. Bare minerals works the best for that! But if you don't have Bare minerals or some type of power substance, try the foundation you have and do that!
the lightest powder substance you can find around the house, even a light pink will do or yellow =]
