Quotation from: Manual of Surgery

When the grafts have healed, it is well to protect them from injury and
to prevent them drying up and cracking by the liberal application of
lanoline or vaseline.

The new skin is at first insensitive and is fixed to the underlying
connective tissue or bone, but in course of time (from six weeks
onwards) sensation returns and the formation of elastic tissue beneath
renders the skin pliant and movable so that it can be pinched up between
the finger and thumb.
