How are glabellar lines formed?
In general, the formation of glabellar lines (commonly known as "11" or "川" lines) is primarily caused by genetic factors, aging, habitual facial expressions, improper skin care, and muscle tension. Glabellar lines can be improved through treatments such as injectable type A botulinum toxin, hyaluronic acid injections, autologous fat grafting, radiofrequency therapy, and fractional laser treatment.
