The lines cannot be removed permanently. Clinically, the frown lines can be improved by injecting botulinum toxin or filling hyaluronic acid, but with the gradual absorption of botulinum toxin and hyaluronic acid by the human body, the frown lines will be gradually restored. 1. Botulinum toxin injection: ChuanZhiLi lines are usually formed due to muscle contraction, through the injection of Botulinum toxin, can briefly inhibit the nerves innervating the muscle movement, so as to reduce the contraction ability of the frown muscle, so as to achieve the effect of removing dynamic ChuanZhiLi lines. 2. Filling hyaluronic acid: for the obvious furrows that have already been formed, the general effect of improving only through the injection of botulinum toxin is not very obvious, and can be combined with low molecular or intermediate molecular hyaluronic acid to fill in, so as to achieve the desired effect. For patients who have ChuanZi lines, if they are self-conscious of the aesthetic impact, they can go to a regular hospital and improve it under the operation of a professional doctor.
