In latex-mode many macros comes with syntax highlighting. For example:

enter image description here

where the argument of the command/macro \bibitem (Fisher:99) has font-lock-constant-face.

I need to do something similar with my own macros. E.g., if I have the string

\mymacro{argument}

I need to fontify the string "argument" so the function (face-at-point) will give me the output my-custom-face. Plus, I need to do it "temporarily". Indeed I need to do it during the running of my scripts. After that I need to restore the original face.

I'm not interested in the visual effect of the face. I only need the function (face-at-point) to return non nil when the pointer is on the argument of my macro.

(highlight-regexp)/(unhighlight-regexp) solved my problem. Here's, as an example, a piece of code that shows what I want to achieve.

(unwind-protect
    (save-excursion
      (highlight-regexp "\\\\mymacro{[^}]+}" 'font-lock-keyword-face)
      (when (string-match "TARGET_REGEXP" (buffer-string))
    (goto-char (point-min))
    (while (search-forward-regexp "TARGET_REGEXP" nil t)
      (redisplay t)
      (unless (string= (face-at-point) "font-lock-keyword-face")

        (save-excursion
          (let ((b (copy-marker (match-beginning 0)))
            (e (copy-marker (match-end 0))))

        (perform-replace (match-string 0)
                 "TARGET_MOD"
                 t nil nil 1 nil b e )))))))

      (unhighlight-regexp "\\\\mymacro{[^}]+}"))

So I'll be asked for a replacement for all istances of "TARGET_REGEXP" (that may be a regexp) but "\mymacro{TARGET_REGEXP}".
