Why Botox pricing works completely differently from surgical procedures
Botox is priced by the unit, or sometimes bundled into a price per treated area, not as a single flat surgical fee the way every other procedure on this site is quoted. This makes comparing Botox quotes a genuinely different exercise: two clinics quoting different headline prices for "one area" may be using different numbers of units to achieve the result, so the real comparison is price per unit, not price per visit.
Ask any prospective clinic directly how many units are typically used for your specific concern, and what their price per unit actually is, rather than accepting a bundled area price without understanding what sits behind it. This single question does more to make quotes genuinely comparable than anything else you could ask.
