Would Fraxel laser be helpful to get rid of atrophy on cheek after a cortisone injection? (photo)

Good question! Fraxel works for acne scarring but the depth the scar might be more effective to treat with non-surgical option (subcision), microneedling/PRP, or Deep Fx (fully ablative CO2 fractional laser).  Another option that some of the other posted below that we recommend and use in our practice is the semi-permanent filler (5 years), Bellafill.  The best answer to your question would be provide by seeing a board certified dermatologist or plastic surgeon that is well versed in these techniques.  The ability to assess the depth, movement of the scar, and appearance with animation is critical. All the best.

It is asking too much for a laser to stimulate collagen enough to fill your scar. I would consider a filler to elevate the scar. My preference is Bellafill because of it longevity. 

Thank you for your question. Regarding that raised area post cortisone injections, I would highly recommend letting it heal and resolve naturally before trying Fraxel. I would give it at least 3-4 months and then discuss options with your dermatologist. Best of Luck, Dr. Heffernan
