OverNite LipMask is a rich and exceptionally nourishing protective balm that sooths, hydrates and restores the skin of your lips while you sleep. Lanolin is the film that locks in much needed moisture and the natural oils and butters provide antioxidants and other vitamins that your lips need. The “secret” ingredient helps prevent the loss of collagen elasticity, slightly increases lip volume and protects the skin on your lips from environmental attacks and possibly prevents premature aging of the lips.
