Closing thread as it is over 3yrs since the last two posts.
To clear things up, Keloid scars grow larger and invade surrounding tissue often having none distinct borders and being bigger than the original wound. They can keep growing forever and don't tend to respond to therapy and often removal isn't an option because Keloids develop due to a genetic mutation (normally seen in Black/ Afro-Carribean people though not totally) and the scar left by the surgery can turn into a Keloid one.
What the vast majority of SH scars actually are are hypertrophic ones. These are where the scar is the same size as the wound was (though can decrease in size overtime). They are raised and reddened at first and this can last a couple of years. It is due to the cuts being gaping and scar tissue needs to be put down to keep the strength whilst it heals and remodels. These do fade with time and flatten. They are aided by having the wound stitched when it is first done as it means they are less likely to develop. They also do tend to respond to creams/ similar in most people, speeding up the recovery of the scar (fading and flattening it) though different creams are more beneficial to some people rather than others.
