The number of subcision sessions really depends on the severity of your scars.
The following is what I explain to my patient, and ultimately its the patients' choice on the treatment option.
Subcision involves the breaking of the adhesions that are tethering to the acne scars, and generally a small amount of fillers is placed in order to:
1) Stimulate collagen (through the use of Radiesse, which is my favourite)
2) Reduce the re-adhesion risk immediately post procedure
For patients with localised rolling scars, 1 session is enough.
For patients with a lot of scars, generalised, or want to do some sort of rejuvenation, a few sessions will be needed.
And I can bet my last dollar that no one can promise that he can break ALL the scars in just one session for a patient with severe acne scarring. We try to break MOST, and then get the patient back again at the next session for the more stubborn areas. Hope this helps!
