I have a method that is said to be very effective here: first, gently prick the scar edge with an embroidery needle, with a distance of about 0.5 mm, and then use our skin's own repair function to make it grow better. The main thing is not to forget to stick the scar in the center, but to start from the edge and then slowly approach to narrow the scope. I don't know if I can, like this.
