What are the possible side effects after Infini RF micro needling treatment with high fluence and long time exposure settings.

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.

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.
