lasers treatments are better than derma rollar, derma rollar was a old method.

nah laser's are not that expansive, the last package i bought was 500 per treatment, 3k will be a rip off

well i don't have deep scars, so there's no need for advance laser resurface tech, i think if my skin is smoother & healthier with 3k it's worth it esp when mine is done by a dermatologist.
