Infini RF settings for the face, why did she do 2.0mm on my cheeks and no 2.5mm?

Each patient is individualized as far as settings. I cannot comment on the settings that were used in your case. I would advise you speaking with your doctor about why these settings were used.

This is difficult to answer without pictures. Infini is a popular treatment, but I prefer Intensif because the needles are non-insulated and give more robust results. For scarring, a combination approach will give the most improvement. I recommend a combination of lasers, microneedling/prp, subcision and fillers. It will take a series of treatments and may need some treatments to maintain. I recommend getting a formal evaluation with an acne scarring expert. Best, Dr. Emer

Whether the pass is 2.5 or 2 doesn't give more or less collagen stimulation. I don't know the reason for this unless the operator felt that the skin wasn't as thick in this area. Also, this is an area of more discomfort and he/she might of felt that more shallow would be more comfortable. Does it make any difference in the results?  Probably not, unless the scars are very thick in this area. There is one comment that states that the Intensif is more robust than the Infini because of uninsulated needles. I disagree. The energy must be less with uninsulated needles so as not to cause pigmentation problems or scarring. The Infini can deliver far more energy than most or all RF needling devices because of the insulation. In fact, it can deliver more energy than the skin can tolerate (with my research) if settings are tweaked. If the doctor desires uncoated needles with the Infini, the needles can be set at 0.5mm and get similar effects to the skin as Intensif. This is done at very light settings in light skin for superficial wrinkles and scars, in very select patients.

There are guidelines for INFINI based upon standard op protocols however every specialist I know will have their own setting based upon your skin type, concerns, level of scarring and skin thickness. I perform all my INFINI setttings myself, the first few shots are 'test' shots - especially if I am treating acne scars. This determines if the solenoid is strong enough for me to goto the desired level - usually 3.5 mm. If I was to target pores, my treatment level would be very superficial- namely 0.5- 1.5 mm and most of the energy delivered there. Bottom line, treatments should be bespoke, and no one should have the same level, energy and pulse duration - as we have skin as individual as we are. I wish you well. Dr Davin Lim
