Is it healthy to do laser co2 after doing derma roller for 6 months?

I would prep the skin with Luminase and Exfolase creams prior to the lasers to help reduce any PIH and hyperpigmentation.Best, Dr. Karamanoukian#Realself100 Surgeon

Yes, I often combine microneedling with lasers to get the best outcomes. For acne scars, I recommend adding prp, subcision and fillers to get the most improvement. It may take a series of treatments and may need life-long treatments to maintain. See an expert. Best, Dr. Emer

Thank you for your question.
It is always best to seek treatment from a professional rather than in home
treatments. Please make sure you get a in person consultation from a
board-certified dermatologist.
