From reading accessible information throughout the web throughout the years about dermal scar tissue formation and evolution I recognize there is vast inconsistency on the definition of how dermal scar tissues are formed and evolve through the years (to which I will further relate as "scar tissue" or "scar", in this question).
I don't have access to plastic surgery literature and I believe that here I should only describe what I understood as the stages of scar tissue formation and evolution from my personal learning so far:
Modeling: A primal scar tissue, modeled (gradually formed) by gradually replacing (or by gradual transformation of) a closed wound tissue;
The outcome is a significantly inflammated, swollen and red scar tissue;
If predisposition exists it is in this stage that the scar tissue could become hypertrophic (keloid or at least ridged) or atrophic (sunken), while the predisposition should be diagnosed and treated or at leased prognosed by at least a plastic surgeon.
Remodeling: The newly formed scar which is significantly inflammated, swollen and red, gradually heals by becoming somewhat less inflammated, less swollen (hence flatter) and less red;
It is in this stage that daily anointing the scar tissue with a standardized good nutrient lotion is considered by some plastic surgeons as possibly improving the outcome of that stage.
Maturation: A phase in which a remodeled scar tissue becomes further flattened and generally lose all redness if any remained;
It is after this stage that it's become adequate to go through scar revision therapies (laser/scalpel/anything else) if this are at all needed.
I also understand that any wound that is suspicious to evolve into a significant scar is best to be diagnosed as soon as possible by a plastic surgeon and that it is generally good to regularly follow up with plastic surgeon in all 3 stages I described to diagnose if complications exist and how to treat them, especially if there is such suspicion.
I also further understand that when an organism is still in bodily growth, formed scars (as in stage 1) could be bigger than if bodily growth was ended, because the wound tissue or primal scar tissue might grow along with the body; thus, scar revision surgery (as performed with scalpel by a plastic surgeon) might be better postponed to after bodily growth was ended - depends on a particular case.
I often came across the claim that scar healing generally takes two years but it is unclear to me in what stage this two years count starts if at all.
Is there a standard model of stages of scar tissue formation and evolution and if so, what are its stages in general and if at all, what can we learn from it about what stage includes a two year healing?
