Hi Daisy. Stretch marks are a type of scar and as such, they are generally not removed completely, but rather improved in appearance with the use of lasers. Coolbeam is a fractional Erbium laser and the reason that the physician that uses this laser markets it is that he says it's one of a kind. While there may not be another Coolbeam laser, there are many lasers that use fractional Erbium lasers, including the Sciton Profractional, which we use in our Torrance, CA office. The important issue is that regardless of who you choose to help you with stretch marks, your expectation should be for improvement rather than complete removal.
