Is fraxel laser treatment effective?

Yes, very effective. The Fraxel Dual offers two lasers: one to target the surface for tone and texture and one to target deeper layers to treat fine lines and acne scarring. Results can be seen immediately but will improve for the following 3-6 months.
Very good. Like any treatment, as long as expectations are reasonable, the fraxel can get very good improvement (not perfection) in skin rejuvenation.
