What is a Fascia Word™?

In the spirit of the What is a Word™/Phrase™ series started by JLee, a special brand of Phrase™ and Word™ puzzles.

If a word conforms to a special rule, I call it a Fascia Word™.
Use the examples below to find the rule.

What is the special rule these words conform to?

HINT 1:

A hint exists among the parallel structure. The words exist within the given words. Astounded, the worker saw this but the answer flew in his face. It was right there on his fascia.

HINT 2:

What is a fascia? A fascia is something that is generally the covering or front of an object or thing. It is a term used across multiple industries, especially construction and biological.

HINT 3:

If you look at the face,
thrice you will trace;
if you see the inverse,
you'll be sure to infer

HINT 4:

Jump thrice, jump once, jump no more
on the face it's not a bore
bounce right back and go again
you'll find the clue in view within

• extatic ... isn't a word? or is obsolete and/or common misspelling of ecstatic, surely. – shoover May 20 '20 at 20:03
• extatic is an obsolete spelling of ecstatic. en.wiktionary.org/wiki/extatic "1749, [John Cleland], in Memoirs of a Woman of Pleasure [Fanny Hill], London: Printed [by Thomas Parker] for G. Fenton [i.e., Fenton and Ralph Griffiths] […], OCLC 731622352: for, whilst he hesitated there, the crisis of pleasure overtook him, and the close compressure of the warm surrounding fold drew from him the extatic gush" – Riddler Jun 3 '20 at 3:27
• ... as my comment said, "obsolete and/or common misspelling" – shoover Jun 3 '20 at 4:12
• as I said, I was confirming which of the two. You said two different things. I told which one it was. It also is a common misspelling but for the purposes of this post, it is simply an obsolete spelling and should be treated as a regular word and nothing less. – Riddler Jun 3 '20 at 4:14
• Is the capitalization important? – Benja Nov 11 '20 at 3:00
