Frown lines, also known as glabellar lines, are the deep lines that appear between your eyebrows when you frown or concentrate. These lines can make a person look angry or tired even when they are not.
One of the most common and popular non-surgical treatments for frown lines is Botox. Botox is a type of neurotoxin that is injected into the muscles that cause frown lines, temporarily paralyzing them and preventing them from contracting. This results in a smoother, more youthful-looking appearance. The effects of Botox typically last for three to four months, after which time the treatment can be repeated.
