Can microneedling cause permanent redness?

Thank you for your question. Treatments must be spaced at least 4 weeks apart for appropriate skin cell turnover, and typically the redness will last 3-5 days. Cell turnover is the skin's natural exfoliation process. The skin naturally sheds dead skin cells through a process called desquamation. Every 28-40 days, on average, a new skin cell is "born" in the stratum germinativum, the deepest layer of the epidermis.I hope this helps. Be well.Larry Nichter , MD, MS, FACS

The redness occurs because your skin gets inflamed or irritated from the needles in the micro needling. It is this inflammation that causes the Improvement in your skin as you start to produce elevated levels collagen.  The redness should not last more than a few days typically and there are certain creams that your doctor can recommend for you to help healing.  Regards,  Dr. Onir
