I [suspected] that the Beauty Tips were not really from Audrey Hepburn.
Fortunately, a reader wrote in with the following news:
"The first 3 paragraphs of "Beauty Tips" were written, not by Audrey Hepburn, but by the late humorist Sam Levenson.
They can be found in his book, In One Era & Out the Other, on pages 176 and 190 of the hardcover edition."
It seems that Audrey Hepburn actually quoted Sam Levenson ...
and then Sam Levenson evidently got edited out in the editions being sent around the internet ...
