A good answer about acne scars separates fading from disappearing. That is the standard this article holds scar advice to: it should tell you which of the two to expect.
The line AAD draws
AAD states the limit in its guidance on acne scars. While acne scars can fade, they rarely go away completely on their own. Fading is possible, and complete disappearance without help is the exception.
Where overpromising shows up
Be wary of any pitch that treats a scar as something that simply vanishes. A claim that time alone will erase it runs against that AAD line. A claim that one product or one visit will wipe it clean is the same kind of overpromise. For a look at what causes scars, which types exist and how they are treated, Cleveland Clinic's guide to acne scars is a steady place to start.
What honest treatment talk sounds like
Treatment talk that meets the standard names your scar type first. It then describes a path in terms of improvement, not erasure. A practitioner who skips the type and jumps straight to a result has skipped the step that makes the result believable.
Reading up before a laser conversation
Scars are grouped by type, and the PMC review of acne scar pathogenesis, classification and treatment shows how that grouping works. When laser work comes up, read a neutral description before the sales pitch. DermNet's page on laser resurfacing explains the procedure in general terms.
Checking in the mirror and in the room
In the mirror, a faded scar can still be a visible scar, so judge by what you see in good light, not by a hopeful description. In a Jacksonville treatment room, ask what the practitioner expects to improve and what they expect to remain. Penn Medicine's page on laser skin resurfacing gives you a neutral reference to bring along. An answer that names nothing as likely to remain has not met the standard.
