This session is about an hour long and includes a light cleanse, 25 minutes of numbing, and 30 minutes of treatment. It is normal to experience redness and/or itchiness in the first couple of days post treatment. Over the next 5-7 days, the treated area will begin to dry out, darken, harden (much like a scab would), and then shed off. Depending on the size and thickness of the DPN, additional sessions may be needed to fully treat. Once treated, the DPN is not expected to return for another 4-5 years.
