Cancel escape, having cut skin (7)
I believe the answer is:
rescind
'cancel' is the definition.
(to rescind is to cancel or repeal)
'escape having cut skin' is the wordplay.
'escape' becomes 'esc' (Escape key on a keyboard).
'having cut' means one lot of letters goes inside another (some letters cut their way into a word).
'skin' becomes 'rind' (synonyms).
'esc' going inside 'rind' is 'RESCIND'.
(Other definitions for rescind that I've seen before include "Annul - discern (anag)" , "Cancel (regulation)" , "Revoke (order)" , "Countermand" , "Revoke (a law/order)" .)
