Colorstay Concealer #40-Medium keeps color crisp - dark circles and zits, hidden - for up to 24 hours. The creamy concealer that disguises all day. Flawless coverage! You get full coverage that's totally undetectable. The technology in this long-wearing concealer wears for up to 24 hours. Works on undereye circles, blemishes, and whatever else you'd rather not see. It is recommended to dab on this long-wearing concealer, using the wand tip. To blend, gently pat it in with your ring finger (the pros never use a pointer, FYI, because it's too easy to apply too much pressure and smear away your concealer). Build until you have as much coverage as you want.
