I have seen bad burns from INFINI RF by people who do not know how to use this device properly. It is in general a vvv safe device but it is NOT by any mean idiot proof.
I will give you an example. This is INSULATED RF, correct? This means only the tip of the needle is 'exposed' and RF is delivered to the end point. Now, if some one dials in say, a pulse duration of 800 and energy of 20 (max energy) with a 3 mm needle, then presses the trigger as the needle is drawn out, guess where most of the energy is delivered? Correct- near the surface of the skin, and hence epidermal injury results. The top layer of the skin is charred.
See someone experienced, and Board Certified and this device is extremely safe, but far from idiot proof.
All the best,

Thanks for your question. There can be side effects associated with any type of procedure. If performed correctly, there should be no side effects with the Infini. Some people may experience redness, bruising, and perhaps hyperpigmentation.
Dr. Weiner is an expert in infini. Like he said, with someone who has experience, this device causes very few complications. However, with any energy based device on the skin you can get scarring, pigmentation changes, and no results. You should be prepared for any cosmetic treatment to have a series of treatments to get best improvement. Only go to an expert. Dr. Emer.
Infini with high intensity gives less coagulation
As Dr Rapaport explained, the high energies cause the tissue around the needles to dessicate around the needle and prevents further spread of the heat. So, actually the low energy, long pulse durations turn out to give the largest coagulation zones, more aggressive treatments. There is no harm in doing this and I have played with all the different settings to try to come up with the best ones. This very phenomenon actually contributes to the safety of the device, acting as a "safety valve" so to speak.
Infini with high fluence + long pulse duration
This is a very thoughtful question. However the answer is counterintuitive. When the infini is used at very high fluence, studies have shown the zone of volume ization is actually smaller than when it is used at a lower fluence. The reason for this is that there is excessive coagulation around the tip and the radiofrequency energy does not have the ability to fan out. The most aggressive treatments are done at lower energy (4) and longer pulse duration. It is important to treat at a deep level when using aggressive settings. I personally have not seen any fat atrophy. Hope this helps. Take care.
