DuWop Twilight Venom Rather than a typical gloss Twilight Venom from DuWop is a shimmering crimson lip stain suspended in a venom-laced liquid lip conditioner containing argan, avocado and olive oils as well as vitamin E. Twilight Venom should be shaken before use (to represent the blending of the human and vampire worlds) and can be applied repeatedly until desired intensity of color has been reached and lips are plumped and revitalized.
