Red scars on face
I don't know what type of treatment caused your injuries but from the photos I would consider pulsed dye laser, done repeatedly at frequent intervals to reduce the redness and improve the scarring. I would also consider injections of Kenalog or 5-FU (fluorouracil) to any thick or raised scars. Make sure that you are seeing an expert laser physician.
Redness After Co2 laser -- Needs Appropriate Wound Care
I suggest you see an expert in lasers and scars. Steroids are not the best option when the skin is thin and healing. Please get on the appropriate skin care. Best, Dr. Emer.
