Skin burns due to liquid nitrogen still there after 3 months. Will my skin go back to normal?

I had 3 moles "dry freezed" using liquid nitrogen. The GP did the procedure twice as the moles did not fall off. Even after the second attempt cryotheraphy didn't work, so the GP shaved them off. However, after more than 3 months I still have brown burnt-like skin around the moles area -this is coming from the liquid nitrogen. It looks disgusting. Will it ever go away?
