32, male, what is the best treatment for redness from facial flushing? (Photos)

You might consider the use of microdroplets of Botox injected in a special grid pattern throughout the red/flushing prone area of the cheeks. It is a is a very simple and relatively inexpensive approach to treating this problem. Although your research has led you to more expensive "bells and whistles" gizmos, you would be wise to exercise a healthy amount of "buyer beware," since the hard science to support the use of any of these devices lags woefully behind the heavy marketing to promote them. And, remember, there's so much misinformation and misleading information out there on the net because there is no regulation of the material nor any fact checker for what's appears there. You would be wise to consult a board certified cosmetic dermatologist, and best of luck.
