pregnancy. Previous treatments have been ineffective or incon-
sistent and not suitable for all skin types (42). Histology of
striae is very similar to that of atrophic scars, so treatment with
NAFL is attempted. The Palomar 1540-nm NAFL is currently
the only laser to gain FDA clearance for the treatment of striae.
One of the fi rst studies with the LUX 1540-nm laser evaluated
51 subjects with striae of the abdomen, legs, buttocks, arms
and fl anks (43). Fluences of 35-55 mJ/mb with a 10-mm tip or
12-14 mJ/mb with the 15-mm tip were performed. Two to
four treatments were performed. Patient and independent
observer evaluations noted improvements of 50% or greater in
all patients at 6 months past the last treatment. Fraxel 1550-nm
