Will skin regeneration ointment be effective for old scars?

I once broke glass when I fell.

I braced myself on the floor and got a big tear around my wrist.

It hasn't gone away even after a long time has passed since the stitches.

Honestly, it doesn't affect my daily life.

Just looking at this place reminds me of that day and gives me goosebumps.

There was a lot of blood, too.

I had a hard time because I had to wait quite a while in the emergency room.

This is the Contractubex ointment I am applying right now.

It is quite famous as a skin regeneration ointment.

I bought this because I heard it's good for surgical scars or marks.

Maybe because it's a scar that's over 10 years old, it's not really working.

It doesn't seem to show up very well in the photo, but

If you see it in person, it looks like a bug, like a trilobite, and it's quite big.

If it does not improve with skin regeneration ointment

I am even considering skin laser treatments.

In case you are like me and using a skin regeneration ointment for old wounds

Has anyone seen results?
