Acne Scar Laser

hi i have some acne scars on my back and I wonder if I should or could have laser removal of acne scars? Is it safe? will it hurt? Has anyone experienced? was their reaction? How long does it take to heal? Does anyone know where is a good place to get it done in Montreal? How much does it cost? the scars are really easy, how many times I had to go? I have an olive-skinned sound (as Eva Longoria)? I need all the details and serious answers. His influence on me to wear tank tops and dresses with no back Please help me, oh and at 15 years and a girl if that helps. ^ O)
