@JonesboyVitamin C and Retin-a or a retinoid like differin or the ordinary can be purchased very cheaply. They are used for cell turnover, and slight textural improvement. No topical will fix/heal - scars. It's a tool used nightly. One piece of the treatment. Of course you would need Dr's treatment as well.

Topicals can prevent skin damage, but wont really reverse any significant damage
