Shimmering regency-era gowns, sparkling jewels, and elaborate wigs were the talk of the ton in Bridgerton’s latest season.

But one of the hit Netflix show’s makeup artists had another task: Making the actors’ makeup look good during sex scenes.

In an interview with Page Six published on Friday, makeup artist Erika Okvist said that the cast had to perform “smooch-tests” to ensure that the makeup could hold up in steamy scenes.

“We want them to look as good as they did when they stepped into the carriage when they step out,” Okvist told Page Six, hinting at the viral hookup scene in the fourth episode between lead stars Nicola Coughlan and Luke Newton.

Okvist said that they used primers and setting sprays to make the makeup kiss-proof.

Her pick for the primer was the Hourglass Vanish Airbrush Primer, which “makes everything look dreamy,” per Page Six.

The primer retails at Sephora for $58.

To give the actors a dewy and glowy look for the intimate scenes, she recommends makeup artist Pat McGrath’s Skin Fetish Highlighter and Balm Duo, which retails for $50.

“That is a wonderful highlighter for cheekbones,” Okvist told Page Six. “Even if you didn’t have anything in your pocket going out and really desperately needed to look just a little bit better, that dual stick is fantastic.”

She called the Fenty Match Stix Contour Skinstick and the La Roche-Posay Anthelios Sunscreen the other “diamonds of the season.” They retail for $32 and $20 respectively.

Okvist said that she also used the By Terry Hyaluronic Hydra-Powder ($54), on the stars, because it does not leave a “chalky” finish.

She added that the intimate scenes were where the actors were “feeling vulnerable,” and it was the makeup artists’ job “to make them feel really special and looked after.”

This season’s fifth episode contains the show’s longest-ever sex scene, which lasts for more than five and a half minutes.

Coughlan told Entertainment Weekly in April that she and her co-lead Newton broke “a piece of furniture” while filming one of the sensual scenes, which she later revealed on her Instagram to be a chaise lounge.

Bridgerton’s third season amassed 28 million views following the week of June 10, when the second part of the season was released, per entertainment media site The Wrap.

Okvist did not immediately respond to a request for comment from Business Insider, sent outside regular business hours.
