Should I Have Carboxytherapy Before Blepharoplasty?

Carboxytherapy would be foolish and possibly dangerous. I cannot state which treatment I would recommend for you. It depends on the anatomy. Blepharoplasty, even in young patients, gives splendid results. Injections can be used, understanding that fat injections are less predictable. Laser resurfacing may play a role. It all depends on the particular problem. But carboxytherapy has no role.

Dear Liponyc,
Carboxy therapy-injecting CO2 into your eyelids could accidentally place gas bubbles into the blood vessels feeding your eyes, and blind you! Further more I do not feel it would have any effect on the lower eyelid fat which lies beneath the eyelid muscle and septum.
Laser surgical methods are the only safe, effective way to permanently remove deep dark circles and bags under the eyes.
I do not use fillers like Juvederm, restylane or radiesse, because injection beneath the eye is dangerous-filler injections have caused blindness in a patient in England. I also do not do fat injections because of the same fear and because injections often leave lumps and are placed in the wrong position.
Effective removal of bags under eyes and dark circles under the eyes requires surgery.

LipoNYC,
The safest thing is to stick with the time-tested blepharoplasty. You need to talk with your surgeon about your expectations and possibilities, but my suggestion would be to do the blepharoplasty first. Good luck with your surgery.
