I need a product to care for laser treatment scars.

I received Fraxel treatment.

Because the procedure was not performed properly

I have a round scar on my temple.

I diligently applied medicine and taped it up, but

As expected, I developed hyperpigmentation.

I can't stand the sight of that hospital, so I'm not going there.

I am wondering if there are any effective products for this kind of scar pigmentation, or if I should still go to a hospital.
