Should I have filler for forehead atrophy after cortisone Injection?

HA fillers are a simple solution to fill the atrophic divot caused by a cortisone injection. If you are concerned about overcorrection, you always have the option to reverse an HA filler. If you want to permanently fix the problem, you can have them inject Bellafill which is actually FDA approved for acne scars but it is the same principle.

Dear raventhecat,
it is hard to tell for sure without an examination. Generally speaking, dermal fillers are great option to fill dents. If you are considering treatment, I would suggest you consult a board-certified plastic surgeon. Only after a thorough examination, you will get more information and recommendations.

It's difficult to give a recommendation with no photos or an exam. Fillers can be used to help improve contours. HA fillers are dissolvable if the results are unfavorable. You may be a candidate for Morpheus8 treatments which combine micorneedling and RF technology to improve skin tone and texture.
