As we age, our facial skeleton decreases and with this, the volume in our lip decreases as well and can cause an aged appearance. The ratio of upper to lower lip should be 1:1.6 with the upper lip sticking out slightly further than the bottom lip. At Radiance, we tailor your treatment to have the appropriate amount of filler to suit your face shape, creating the perfect definition. An assessment of your profile, lip size and facial proportions are imperative to give a natural look.
