Wondering if switching lasers will help

I’m looking for treatment in the Medford Oregon area. i have an appointment in a couple of weeks at the Dermatology & Laser Associates of Medford office. do offices that specialize in dermatology (rather than the ‘aesthetic spa’ place i was going to earlier) tend to be on the more credible side? i’m sick and tired of hearing “our laser is the best in the valley” yet get no results. At the Dermatology place in Medford, they use a Gentle Lase.
