Active Fx vs E-Max for resurafcing and tightening
not a chance!
the active fx is much more effective.
CO2 laser (the technology behind active fx) is the gold standard for skin resurfacing and has been so for several decades. "elos" technology is a marketing gimmick. the syneron devices work ok, but nothing special.
active fx downtime is about 4 days of mild swelling and redness, with a week of sunburn-like redness afterwards. not a huge price to pay for real tightening of fine lines and pores.
hope that helps
