Laser Treatments That Give Better Results Than Palomar Laser?

I have an ethnic background of mixed origin (African American and Caucasian) and I tend to hyperpigment easily from breakouts. I recently did a series of six Palomar laser treatments to minimize mild acne scarring, mild hyperpigmention, and somewhat enlarged pores. The procedure seemed to be a success and my skin looks good, but it really doesn't look significantly different than before the treatment. Are there other laser treatments that can give me better results?
