When considering lip augmentation, you want a Hyaluronic Acid (HA) filler that utilizes flexible cross-linking technology. This allows the filler to integrate seamlessly with your delicate lip tissue so it moves naturally when you speak and smile, avoiding a “stiff” appearance. Restylane uses XpresHAn Technology™ specifically designed for flexible, natural-looking lip volume and enhanced color. Another highly reputable and smooth-flowing option commonly used by injectors for subtle lip enhancement is Juvéderm Volbella XC.
