It’s been 2yrs and I still have a bruise after my breast reduction (Photo)

This does not appear to be a bruise. It may be the result of the steroid injections. An in person evaluation is best, but you may have improvement with laser treatments. I encourage you to return to your surgeon for an evaluation.

No, it is not a bruise but appears to a some left over areolar pigment. this can be revised if you wish and removed,

Given your history, I think the skin discoloration is likely secondary to the steroid injection. We utilize steroid injections to soften and flatten hypertrophic scars. Unfortunately, there is a risk that the skin becomes thinner and exposes the underlying vascularity. You do have options though and those would be non-surgical and surgical. Non-surgical options would be laser, microneedling, and radiofrequency to name some. Surgical would be scar excision but removal of the entire discolored area may require too large of an excision.
