Rejuran should be considered a supplement to lasers for scar treatment (as opposed to a treatment method on its own); it theoretically provides a more optimal biological framework for wound healing and hence scar remodelling.
It is not necessary, and scar treatment with fractional lasers alone can produce a good 50-70% improvement of atrophic scars.
It can, however, make the healing better and/or faster. Such an investment can be wise to maximise your time and money spent on the fractional laser sessions.
Other techniques can be combined, including subscision and subdermal filler placement.
There is no one stop solution, and a combination of treatments tend to produce a better end result in the long run.
Hope this helps.
