Do I have ridging scars? (Photo)

What you’re describing—the “hills” forming in the skin and redness—does raise some questions, but based on the timing and the dermatologist’s diagnosis, it seems like you were experiencing an inflammatory reaction, not necessarily ridging scars. Ridging typically refers to raised, thickened scars that can form after surgery, especially if there’s prolonged inflammation or improper healing.
The good news is that at 7 months post-op, most inflammation should have subsided if it was contact dermatitis or an inflammatory response. If you still see persistent raised areas or feel that the texture isn’t smoothing out, it’s worth monitoring. Dermatitis and post-surgical redness can sometimes mimic the appearance of early scar formation but often improve with time and treatment.
A dermatologist is qualified to diagnose these types of skin reactions, but if you’re still concerned, you could consider getting a second opinion, perhaps from a specialist in post-transplant healing. In most cases, treatments like corticosteroids or anti-inflammatory therapies can help resolve these reactions if they persist.
