"...Treatments will never totally fix the problem, and that your skin has a -memory-, and once you have a scar you can never get rid of it. I was told you can temporarily remove the layers of skin and scaring but it will eventually come back without regular maintenance."
Then a doctor comments on superficial scars, and that they can be removed.

After reading that, I'm curious as to what superficial scars are in terms of scaring. Mine aren't deep at all, they're just wide. Like surface scars. Less half a millimeter deep. I know I should be thankful for them being shallow, or just level, at the surface... I still see edges, and the new one, 7 months, is a little pinkish. And they're in very distracting places... if they were in different places I wouldn't care. But between my eyebrows, that ones about four years old, and on my forehead, 7 month, it sucks. And I feel they can be easily helped...
But I was wondering, also, how long after a wound would you consider it a scar? Because I hear scars aren't fully matured until two years after.
i would take anything on realself with a grain of salt. keep in mind it's just a place for doctors to promote themselves and get you to use their services.
i have definitely seen some people get real and lasting results on this forum, you just have to dig deep to find it. none of them were forehead related though 
I agree with rentedname, Realself is not a good source of information.
Your skin is an organ. Like any organ in our body it changes over time. In the case of acne scarring it's sadly not easy to treat. There's no magic pill, no diet-altering fix, no awesome lotion. But that doesn't mean we can't do something about it. Focusing on how old the scars are or how long it takes for an indentation to be classed as a scar seems trivial to me. All I care about is seeing improvement, and there is no better time to start than right now.
As we age our bodies do not create as much collagen and so our skin suffers as a result. We get wrinkles, fine lines and our acne scars look worse. Just one of the wonders of aging. That is why no treatment can possibly claim results as being permanent because, the state of our skin is ever changing. Your skin does not have a "memory" but it stands to reason that areas that have been damaged in the past are more likely to look worse than other areas as we age.
Superficial scars are those that do not go down deep enough and/or do not attach themselves to the subcutaneous tissue (like in most rolling scars). Superficial scars are easier to treat and you should see fantastic results from lasers or dermabrasion etc but if you bank on removing them permanently and forever then I think you'd be setting yourself up for disappointment. I'm not trying to say that the treatments we put ourselves through are all for nothing, far from it. I'm saying that we need to be realistic and only ever expect improvement. Anything more than that should be a bonus. Pure and simple. 
I know for a fact that in order to keep my skin in a state where collagen is forming at a good rate and to continue to minimise my scarring I will be undertaking maintenance treatments for the rest of my life (or at least until I decide to just age gracefully). I think of it as having a condition. In order to keep it under control I need constant medication, if that makes sense.

I agree that as one's skin continues to age, there is a loss of collagen that can make ome's scarring look even worse.
My mom had disfiguring acne scarring that only looked worse as she got older - she was also a heavy smoker that only compounded things.
My plan is to continue doing dermarolling, chemical peels, use a facial cream with ester c, and sunscreen to protect my skin.
Once you attain a certain level of improvement, it will be important to maintain whatever gains you have made.
I have no intention of going backwards........
