Hello I have a very small but ugly scar on my lumbar region (it is flat, I have treated with both silicone and steroid tapes) however it was in high tension area and the scar texture looks bad it is irregular . You can clearly see that n incision was made there and it's very jagged looking (though not hypertrophic) I am interested in dermabrasion to smooth it out and blend it more.. I understand de pigmented areas of scar will remain depigmented but I'm hoping to blend it in more.
