Dermal Filler can be used for either lip rejuvenation or enhancement. It can be used to add volume to your lips, to improve border definition of the upper and/or lower lip and to create a stronger Cupid Bow. Dermal Filler can also be used for lip enhancement to add volume and improve lip definition in younger lips. For rejuvenation, the vertical lines around your lips may also be treated. This gives a more youthful appearance and will also help prevent lipstick bleeding.
