There are several body cleansers in Megan’s shower.
The first from the left is a body and hand wash by Jo Malone.
When she gets near the window (from where she can see the train to New York passing through), the other three products are clearer.
The first is Eucalyptus body cleanser by C. O. Bigelow.
The second is Roger & Gallet Rose gentle shower cream.
And the last tube is Elixir White hair & body wash, another C. O. Bigelow product.
Thanks to Jay for the submission and for telling me about this film: I had never watched it before and I enjoyed it a lot.

It’s the marbled lipstick Glissando, launched in 1964 by the American brand Du Barry.
Available in six shades (“from light-struck pinks to muted ambers to rich reds”), it was housed in an elegant silver and gold metal case.
It’s not a coincidence that later in the film we see several products from the same line on Pepa’s vanity. Pepa (Carmen Maura) is the former mistress of Iván. She’s another woman “on the verge of a nervous breakdown”, just like Lucía: they’re in love with the same man (who has dumped both of them for another lover) and happen to use the same skincare.
When María Cardenal (Assumpta Serna) re-applies her lipstick, we can see it falling on her lap.

The first is the spicy-fruity Dolce Vita by Christian Dior, a creation by Pierre Bourdon and Maurice Roger. Too bad it was launched in 1994 (the show is set 8 years earlier!). I think the bottle was chosen simply as a decoration.
The other bottle is Safari by Ralph Lauren. Historically speaking, it’s another inaccuracy, because this fragrance, created by Dominique Ropion, was launched on the market in 1990. Too recent to be sitting in a Parisian bathroom in the mid 1980s.
While Cecile (Jean Seberg) is applying sunscreen on Elsa’s shoulders, Raymond (David Niven) is reading a magazine with an interesting back cover.
A few instants later the magazine is fully visible: it’s Elle.
The back cover advertises a very popular French perfume – Soir de Paris by Bourjois. Created by Ernest Beaux (Chanel No. 5’s “dad”), it was originally launched in 1928 on the American market as Evening in Paris. Thanks to the huge success it had in the U.S., it was finally launched in Europe with a French name. The blue bottle with silver accents was designed by the painter Jean Helleu.
