I got white spots on my sidewalls of my nose from too frequent steroid injections.

     The skin hypopigmentation may improve with time, but this is always a risk with steroid injections.  I personally do not inject steroids after rhinoplasty.  Kenneth Hughes, MD Los Angeles, CA

You might want to consult with a dermatologist. They may have some additional options along the lines of topical tar preparations that have helped some people in the past. I have even heard of people trying topical Latisse in an attempt to darken the skin. The bottom line is that hypo pigmentation can be permanent. It might be worth a try to you, though.

White spots or hypopigmentation as a result of steroid injections is a difficult problem to treat. If they are recent injections, the negative side effects may ware off with time and no treatment at all.  I have performed repeated subcutaneous washings with saline injections to dilute any potential retained collections of the steroid. I only have anecdotal data that this works though.
