Scarless wound healing is a concept based on the healing or repair of the skin (or other tissue/organs) after injury with the aim of healing with subjectively and relatively less scar tissue than normally expected. Scarless healing is sometimes mixed up with the concept of scar free healing, which is wound healing which results in absolutely no scar (free of scarring). However they are both two different concepts.
I think this has been discussed already, but it's happening again... I think it's still really confusing that posters are still using the phrase "scarless healing" when that's not really what anyone wants. Scar free healing is what this thread *should* be about, as per dextran hydrogel.
I'm afraid that scarless healing, being a *subjective* measurement of "less scar tissue", is highly likely to just be a waste of time to get excited about. I'm sure all of those silicone gel and derivative treatments out there could claim to be scarless healing.
Most scar treatments nowadays seem to frequently yield a placebo result than something objective and concrete. The only thing I'm actually excited about anymore is something that truly promises objective results, i.e. scar free healing.
