Is it a matter of how deep the cut is? Because I have some shallow cuts from work that have left scars, and some pretty deep ones that left no trace once healed up. What’s the deal?!
In: Biology
There are a number of factors that go into whether a cut will leave a scar.
hypertrophic scars or keloid scars are raised scars that come from deeper cuts, where your body spams collagen proteins haphazardly to try to get the wound closed as quickly as possible.
If the cut is a regular shape it is easier to heal. surgery incisions are usually straight lines made with a very sharp scalpel so as not to tear the edges and create any ragged flaps of skin that will be difficult to heal. Some weapons are created specifically to have a nasty shape that will create wounds that are difficult to heal. Irregular wounds are more likely to scar.
Also cleanliness can determine scarring. if your wound is clean there is much less likelihood that it will scar.
basically, scarring is your body freaking out over a wound and just throwing material at it to get it closed. if a wound is clean, shallow, and an easy shape to heal, then your body won’t spit extra proteins at it.
