This is quite easy. Subcision happens primarily under the skin surface. Most of the surface is left unharmed and intact. Only little punctures in the skin will be visible as small crusts that peel in 3-5 days. Simply wash your skin with a facial cleanser or mild soap in the morning and evening and apply a gentle moisturizer (eg. Cicaplast or Cicalfate). Bruising may be covered with make-up the first day after subcision. Avoid smoking for the first few days (impairs healing).
