Dr. Dean Kane Q & A
Q. I turned 23 and I have noticed “dents” above my eyebrow. And I also have a deep line in between eyebrow. What treatment would I need to decrease appearance? Creams? Boxtox? Laser?
A. The corrugator muscle is one of 3 muscles in the glabella group of muscle between the eyebrows. The reposition the eyebrows into a “down and in” direction by contracting the skin to the bone at the top of the nose creating an angry or scowled appearance. It also pulls the forehead and inter-brow skin toward each other in a vertical single or double furrow or line.
The edge of the corrugator muscle can extend significantly upward and outward to the lateral forehead. When it contracts, it can produce one or more dimples over the brow depending on its interaction with the frontalis and orbicularis muscles.
The FDA approved Botox and Dysport injection technique does not adequately address the contraction of this muscle extension and the additional recruitment of skin towards the middle.
It will take a well experienced Board Certified Injector to understand the dynamics and interplay of these muscles of facial expression to know where and how deep to inject muscle relaxers such as Botox.
I hope this helped. All the best!
