Fraxel is a well-marketed brand that has high recognition and recall. We have trialled this laser many times and found it to be painful and produce gross swelling for minimal results.
The Pixel laser in our experience has less side effects and has quicker return to work but can be more effective. The reason for this is the laser beams can be stacked in one spot and go deeper.
PicoSure laser is newer development being nanosecond technology which penetrates deep into the skin with very short bursts causing very little upper layer swelling and redness. It can be considered the no downtime skin rejuvenation treatment.
In our opinion PicoSure for those with very little downtime or pixel for those with a recovery time of 1-5 days are the best options.
