The low power laser effects on striae rubra Striae are a pathology that hit men, women and teenagers in several ages. It is characterized by the rupture of the elastic fibers located in the dermis. It has an inflammatory and edematous nature, linear appearance and variable length and width. According to the evolution of the health state, it becomes whitish, with a nacreous appearance. The low power laser, in turn, is a non-ionizing electromagnetic radiation, characterized by the monochromaticity, coherence and directionality. It has the ability to provide for body a better response to the inflammatory process, with consequent reduction of edema, painful symptoms and cellular biostimulation. This case study aimed to assess the laser effects in striae rubra. The final assessment demonstrated that the chosen protocol had a significant and satisfatory result.
