Which one has a better effect on greater collagen stiimulation or pretty equal with each session ?
CO2 is the Gold Standard, but Fraxel does not make a good CO2 laser (rePair), much better CO2 lasers out there, Genesis is a slow but good method of collagen production. You do need to see someone that has all the lasers, Co2, 1550 Fraxel , 1064 Genesis, etc.... then negotiate downtime, sessions, expected outcomes and match it with your skin type. Its more complex than using 'a laser'. I wish you well, DR Davin Lim. Brisbane. Australia.
