Do scars generally continue to undergo beneficial changes after maturation? I understand that succumbing _wound healing_ , a modulated scar would go through a process of _scar healing_ which I understand to be _remodulation_ and _maturation_. Do scars generally continue to evolve in beneficial ways throughout the life of a human? That is to ask; might it be that a scar's evolution could be comprised of two major stages "primary" and "secondary" and that the primary stage is consisted of _remodulation_ and _maturation_ and the secondary is comprised of "post maturation" evolution which could last during all life of a human? In general, scars do get changed after being "healed", at least by general bodily changes from aging effecting all tissues in general (including the scar tissue), but there might also be a "post maturation evolution" as well.

The collagen that holds together scar tissue is continuously degraded and replaced. (Plastic and Reconstructive Surgery, 1976) If collagen synthesis slows down, due to scurvy for example, old wounds can in theory reopen. Historic records of sea voyages contain descriptions of long-healed wounds opening back up in scurvy victims, and these cases are cited authoritatively in some papers (e.g. Annals NYAS 1961), but it is difficult to test experimentally.
I would describe this more as 'maintenance' of the scar, rather than as 'continuous healing', but it may be of interest to you.
