It is normal to have redness after microneedling for a few days. This is due to inflammation and histamine release.For best results with microneedling combine with lasers like fraxel, aerolase,, Clear+Brilliant, C02, or Erbium to get improved collagen. We suggest all patients follow up with facials like Silk Peel Dermalinfusuion to hydrate, exfoliate and provide the skin with antioxidants. Sun protection is also essential. If it doesn't resolve in a few days, please consult your physician and get vascular laser treatments to decrease the redness and swelling -- excel V, v beam/pulsed dye laser, or yellow laser. LED therapy with lightstim right now would also help. Best, Dr. Emer
