Fractional lasers have become widespread in dermatology owing to their efficacy and safety. Comparative analysis of histological features after laser rejuvenation using a 1064‐nm fractionated handpiece picosecond laser with different energy fluence levels (1.1 or 2.1 J/cm 2 ). An open‐label, study of 28 women aged 36 to 60 years with signs of age‐related photodamage and skin changes of the face and neck was conducted using a fractional picosecond 1064 nm laser in low vs high fluence. The clinical assessment at 3 weeks showed more pronounced effect on facial skin rejuvenation with the higher fluence of 2.1 J/cm 2 compared to 1.1 J/cm 2 . The effect and safety of laser rejuvenation using a picosecond laser has been shown with more pronounced histological effects at higher fluences.
