What problems could I potentially encounter with the Infini by Lutronic?

Thanks for your question. Initially, you will feel slight pressure when the needles are inserted.
Your provider will work with you to maximize your comfort level.
Tolerance level varies per patient. In comparison to other devices, many
patients find the INFINI more comfortable.The initial redness following the treatment will subside within an hour.
It can take 24 to 36 hours for the redness and/or swelling to
dissipate. You are able to resume your daily activities immediately
after the treatment with no exercise or sun restrictions.

When you consider a treatment with any device, one should always look into the potential side effects. Having done many of these procedure, I have seen no long term problems. Initially, there will be some crusting and bruising and small needle marks present for 24 hours. The advantage of this device is that you can use it on all skin types. Now with numbing cream and the mesoram local anesthesia, there is minimal if any discomfort. It can tighten skin up to 25 percent with essentially no downtime.

In my opinion, Infini has a minimal amount of side effects when used by a knowledgeable physician . The most common are swelling after the procedure, small crusts in the area of the needle penetration, and potential for small raised "brail" like bumps on the neck. I have not seen any fat atrophy from Infini. It is excellent for treating depressed acne scars as well as tightening the face. My only concern with your history, is that Infini will not improve the hypopigmented patches. For this I would probably recommend a fractionated erbium laser  (Fraxel Restore)  or eximer UVB  laser in addition  to the Infini.Seek a physician who has extensive experience with the infinii. Ask to see pictures of patients with similar type of scars.Hope this helps. Good luck.
