Clear and Brilliant laser and Vbeam for red marks
I would begin with v beam laser and Clear and Brilliant laser. Redness and discoloration will improve with these scars.
Red Spots on Nose
I suggest seeing a cosmetic dermatologist this can be treated by a number of lasers without complications. Best, Dr. Emer.
Red marks after acne on nose
These can be easily treated with a vascular laser, either the VBeam or Excel V. Cost shouldn't be much because it will take less than 5 minutes.
Red Marks and scars
It is difficult to tell from these photos if these are scars or hemangiomas. These could be treated with the V-Beam laser or electodessication depending on the nature of these lesions. Best, Dr. Green
Red spots on nose
These lesions should be examined in person by a dermatologist to make sure that they are indeed acne scars. If they are, and again they need to be seen in person, then a laser can be used to target the blood vessels which are making them look red. The cost will vary, ~$200.
