Cortisone induced atrophy and hypopigmentation

Last month I received cortisone shot for a pimple on my chin. Within the last few weeks, I have developed a shallow dent and hypopigmentation around the site of the injection.  I am not aware of the amount of steroid that was used, but I was assured at the time that it was a lower dose due to my concern of atrophy.  I have a dark complexion so I am concerned more so about the loss of pigment.  In your experience, is this temporary?  If so, how long will it take for the pigment to return?  What are my options if it does not return?

Also, how long does it take for the atrophy to reach full potential – meaning, is there a possibility it could get worse?

Thanks for your help!

Hello,
This hypopigmentation is due to post inflammatory hypopigmentation. Post inflammatory hypopigmentation is very difficult to treat but sometimes it goes away on its own after exposure to the sun. Creams like  Elidel cream or Protropic can be used on these hypopigmented  areas but at such a young age it is not advisable to use them . If the symptoms still persist then  you can talk to your dermatologist about laser-assisted chemabrasion(LACA).

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
