xeomin | muscle Relaxant When you squint or frown, the muscles contract causing the skin to furrow and fold. Gradually as your skin ages and loses some of its elasticity, these repeated contractions can cause persistent upper facial lines. Xeomin acts on the nerve endings in muscle tissue to reduce the ability of the muscle to contract.See our estimate treatment costs below and get in touch to feel refreshed. treatment cost forehead$80 - $320 frown$160 - $480 crows$160 - 560 chin$80 - $160 upper lip$80 - $160 hyperhidrosis$1000 Book Now
