Hyperbaric Oxygen and Pixel Laser
I am not sure that hyperbaric oxygen at 4 months post-procedure will help, but I am not sure that it won't. The major issue around hyperbaric oxygen and cosmetic surgery is that there is very little data. So you certainly may try, but it is unclear if it will be a measurable difference. I would ask your treating physician their opinion and I would ask the hyperbaric physician, as well.
