In short: No, sorry.

They did away with the scars from Mass Effect, and replaced it with Renegade scarring. Due to your ressurection from Cerberus being apruptly cut short, your scars never fully healed. If you make more Renegade choices, your face will become more scarred as you go. You can heal the scarring by performing Paragon actions, or avoid it all together with an upgrade in the Med-Bay.
