I had my milia under and near my eyes removed by a doctor. I still have light brown scars after 3 and half weeks! What to do?

I had my milia under and near my eyes removed by a dermatologist. (I'm not sure if it was keratosis or milia, but i believe it was lancet that the dr. used). The scabs fell off after a few days, but now I still have light brown scars where they were removed. It's been over 3 and half weeks! Is this normal? I thought that this procedure shouldn't scar. What can I do at home to fix this? Should the doctor follow up with treatment since it's taking unusually long? Thanks!
