Laser Treatment For Broken Capillaries and A Large Blister Formed and Popped, Leaving a Red Mark?

I had laser treatment to remove broken capillaries around my nose. One on the tip of my nose where a rather large blister formed and popped leaving a red mark. It has been more than 6 weeks and though the blister has somewhat healed it has left a small mark and the tiny broken capillary is a darker red making it quite prominent against the rest of the light skin. I am wondering if and when it will return to normal and what are my options. I was told to put bleaching cream/retin-a on it.
