Would Taking a Blood Pressure Medication Effect the Outcome or Healing of a Needling Procedure for Scars?

I had a skin needling procedure done for scars on my legs. It is already 2 weeks after the procedure and the treated area of the skin is still red. How do I get rid of the redness? I am also taking high blood pressure medication which I was not informed of the side effect before the procedure. Please help, Thank you so much!
