1. Quoted Per Session, Sold as a Series
The per session price on a menu is a unit rate, not the cost of the treatment, because radiofrequency microneedling is not delivered in one visit in ordinary practice. It is planned as a course spaced over weeks rather than delivered in a single visit.
That has an uncomfortable consequence for comparison shopping. Two practices quoting per session figures a long way apart may be describing courses of different lengths, and the cheaper session can belong to the more expensive plan. Until you know how many sessions each practice plans and what the total is, you have two numbers rather than two quotes.
The literature does not hand you a session count either, and any page that claims one is inventing it. A 2025 systematic review of fractional radiofrequency microneedling for acne scarring covering 16 studies and 481 patients concluded the treatment is likely effective as a monotherapy while stating that more randomized trials are needed to establish appropriate treatment parameters. Protocols in the published work vary, which is exactly why yours is set at an assessment.
So ask for the plan: how many sessions, at what interval, on which areas, at what total, and whether a package rate differs from the single visit rate.
