Last week's Academy Awards were as much about beauty products as fashion.

Take Lupita Nyong'o's lip balm. Ellen DeGeneres did, grinning and saying, "That's worth something." FYI, it was Clarins HydraQuench Moisture Replenishing Lip Balm, $24, at Clarins counters, clarins.com.

Penelope Cruz's look -- inspired by Sophia Loren -- dazzled, thanks to makeup artist Charlotte Tilbury's own WonderGlow (available this fall) for a candlelit complexion, and Lancôme Modèle Sourcils brow gel, to set that perfectly arched brow, $25; at Lancôme counters and lancome-usa.com.

Maria Menounos offset an understated white Johanna Johnson gown with bold nails -- Butter London's Patent Gel Tops & Tails Base -- and Topcoat gift set, $40, and Nail Lacquers (Pearly Queen, Union Jack Black, plus sparkly Gobsmacked on the tip), $15 each; at butterlondon.com.

Jessica Biel went Veronica Lake sultry, thanks to L'Oréal Paris Oleo Therapy Perfecting Oil Essence applied from middle to end of hair (while damp, before styling) to smooth tresses, add silky shine, $12.99; at drugstores and lorealparisusa.com.
