Other options other then oratane (roacutane)?

Hi guys ive been on a drug called oratane for about 3 months and to start my skin was preety fine just some acne on my chest which is harder to get rid off as acne gets harder to get rid off the lower it is. Now 3 months later i have preety much perfect face and chest only a couple im wondering if there are any other ways except roacutane to clear acne/acne scars and i dont mean creams or anything i mean like maybe laser surgery and can that be as effective and roacutane i dont care about the cost but does anyone have some ideas i live in sydney australia
