Lasers and lights for the treatment of striae distensae.

Striae distensae (SD) or "stretch marks" are a common and well-recognized dermatologic entity affecting patients of all ages, genders, and ethnicities. The treatment of SD has long been plagued by disappointing outcomes and remains a frustrating entity for both physicians and patients. While striae may become less conspicuous over time, they rarely resolve without intervention. Inspired by the success of lasers for the treatment of scars and rhytides, these devices have been applied to the treatment of SD in the hopes of achieving similar efficacy.
