I sell LipSense by SeneGence. The waterproof, smudgeproof, kissproof lipstick that stays on up to 18hrs. We have over 50 colors that can be mixed to create an unending number of combinations of colors. This lipstick is not a stain. It molecularly bonds to the lip with the use of our lip glosses. One tube can last anywhere from 6 months to 3yrs depending on how often you use it. Please contact me if you are interested in trying out this life changing lipstick!
