title: Fractional CO2 Laser Versus Intense Pulsed Light in Treating Striae Distensae.
abstract: BACKGROUND
  Striae distensae are linear atrophic dermal scars covered with flat atrophic epidermis. They may cause disfigurement, especially in females. Many factors may cause striae distensae such as steroids, obesity, and pregnancy. Although there is no standard treatment for striae; many topical applications, peeling, and light and laser systems have been tried.
  
  
  OBJECTIVE
  To evaluate and compare the efficacy of fractional CO2 laser with intense pulse light in treating striae distensae.
  
  
  METHODS
  Forty patients with striae distensae were recruited. Twenty of them were treated by fractional CO2 laser and 20 were treated with intense pulse light. Length and width of the largest striae were measured pre- and post-treatment. Patient satisfaction was also evaluated and graded. Patients were photographed after each treatment session and photos were examined by a blinded physician who had no knowledge about the cases.
  
  
  RESULTS
  Both groups showed significant improvement after treatments (P < 0.05). Patients treated with fractional CO2 laser showed significant improvement after the fifth session compared with those treated with ten sessions of intense pulsed light (P < 0.05) in all parameters except in the length of striae (P > 0.05).
  
  
  CONCLUSIONS
  The current study has provided supportive evidence to the effectiveness of both fractional CO2 laser and intense pulse light as treatments for striae distensae. Fractional CO2 laser was found to be more effective in the treatment of striae distensae compared with intense pulse light.
