Aesthetics and medicine: cuts that leave no scar

Technology at the service of aesthetics and medicine this morning.

We found a way to heal cuts without leaving a scar.

Besides, it's perfectly natural.

This is a finding of researchers from the University of Pennsylvania in the United States.

They discovered a protein secreted by the bulb of our hairs and able to make us heal without leaving the slightest mark.

We could therefore have a huge cut, dozens of stitches… with this protein, the skin will regenerate perfectly without the ugly blisters of the scars.

This is an important discovery, because, until now, it was thought that it was impossible in mammals.

That only fish and batrachians were able to heal without leaving traces.

Well, it's also possible on human skin… Even if, for the moment, it's only about skin grown in the laboratory.

Do we know why the skin scars and doesn't reform normally?

Because the injury destroys the hair bulbs and the little bags of fat just below the skin.

However, without these two components as guides, the skin will regenerate haphazardly, with a funny aspect typical of scars.

But with the protein discovered by the researchers, the bags of fat reform.

Hair bulbs too.

So the skin becomes perfectly normal again.

For now, it's still research.

But we can already imagine creams or dressings with this protein.

We will then be sure to have no scars once healed.

Does it also work on existing scars?

No Unfortunately.

This technique only works between the 15th and 28th day after the injury.

Before is too early.

Then it's too late.

You can always try to reopen in exactly the same place to use the protein.

But nothing says it works.

In any case, this discovery shows that our skin has a much greater capacity for regeneration than we imagined.

Go find out what we find tomorrow.

Maybe we can regrow a finger or a piece of severed ear.
