Get fuller-looking, hydrated lips with BYS Lip Plumper. When applied to lips, the ultra-shiny, lightweight gloss creates a tingling sensation, helping to create an instant, more plumped lip. The gloss has also been formulated to include the ingredient Maxi-Lip; a collection of peptides which help to stimulate collagen production, leading to longer-term fuller, smoother lips. BYS Lip Plumper does not leave lips feeling sticky, and can be worn alone or over lipstick.
