Liza (Sutton Foster) is sitting in the make-up trailer on the set of the photoshoot for the Infinitely 21 advertising campaign. Among the several products, I've spotted Kérastase K Laque Couture hairspray and Ouai finishing créme.
Kelsey (Hilary Duff) is using Maybelline Great Lash waterproof mascara. On the washbasin there's a tube of E.L.F. BB cream.
Maggie (Debi Mazar) would like to shave Donna's moustache, but the woman - outraged - refuses. The Gillette Venus Swirl blue razor is of no use, then.
There's a jar of Olay Regenerist micro-sculpting cream on Lauren's bedside table.
Liza Miller (Sutton Foster) puts on some Olay Regenerist micro-sculpting cream. Her friend Maggie (Debi Mazar) comments on it and mentions the brand. You may remember a similar scene (i.e. a perfect example of product placement) was in the eighth episode of the first season.
There's an EOS Smooth Sphere lip balm in Pomegranate Raspberry on Kelsey Peters' desk.
There's a bottle of Dove Deep Moisture nourishing body wash on Josh's bath-tub. The label has been covered, so you can read "Park" and not the actual brand on it. The same has been done to a tube of Noxzema Ultimate Clear daily scrub. Thanks to Emily in the comments for the Noxzema id.
