After a dermaplaning procedure, you may experience some redness in the treatment area for two to three days as the skin heals. That said, you may also notice improvements immediately after a dermaplaning session, despite the redness. For most people, it usually takes a few days before the redness completely goes away, and peak results develop in the treatment area. Once results do show up, they should last for at least three weeks to one month of the initial procedure. As such, many clients come back for monthly dermaplaning appointments or for every other month.
