The secret to Sienna Miller’s gorgeous Met Gala glow: Makeup artist shares insight into actress’ beauty regime as her stellar renaissance continues

Sienna Miller’s makeup artist has shared the secret behind her stunning Met Gala glow after joining a star-studded lineup on the red carpet on Monday night.

The actress, 42, showed off her boho-inspired fashion sense in a flowing white lace dress, four months after the birth of her second child.

Now, makeup artist Wendy Rowe has shared the exact product she used to create Sienna’s barely there look The mirror.

She started Sienna’s transformation by applying Code8 Beauty’s Radiate BB Cream to create a refreshing and radiant look, using a combination of the shades NW30 and W20 match her skin tone.

The foundation is said to provide ‘long-lasting coverage, a dewy glow and improved skin nourishment’, and is enriched with argan seed oil.

Wendy then revealed that she used the Code8 Seamless Cover Concealer to conceal any blemishes and dark circles.

She said: ‘I used the Seamless Cover Concealer in NC15 under her eyes. I then added the Bronzer in the color Summer Glow. After this, I set Sienna’s face with the Matte Velor Powder in Medium, concentrating on the T-Zone.’

Use Highlight and Sculpt on her cheekbones, the bridge of her nose and the cupid’s bow to accentuate her features, Wendy then moved to Sienna’s eyes.

Wendy added: ‘For the eyes I used Eye Shadow Palette Iconoclast 1 on the lid, and in the eye socket line 2. Carbon Black Eyeliner was applied super skinny close to the lashes,’ followed by the Lash Sophisticate Mascara.

To complete her flawless look, Sienna’s lips were lined with the Salvador Lip Liner and filled with the Color Brilliance Lipstick in St Germain.

The fashionista and her boyfriend Oli Green, 27, welcomed their first child together, a girl, in January. Sienna also has a daughter Marlowe, 10.

The actress has barely aged a day since starring in Layer Cake and Alfie more than 20 years ago – and previously credited yoga and her love of Marmite as the secret to her age-defying looks.

Sienna joined make-up artist Charlotte Tilbury and models Poppy Delevingne and Cora Corre at Lady Lola Bute’s 25th birthday party, held at the family’s Mount Stuart House on the Isle of Bute.

Sienna stood out from the crowd in a £3,900 silk mesh dress by Annie Doble of Annie’s Ibiza.

It featured hand-beaded crystals in the shape of a spider web and a backless design, while the sheer nature of the dress highlighted her lithe figure.

She paired the look with a nude bodysuit and a tan, as she had just returned from a family holiday in Croatia.

The designer also produced a custom-made outfit in a 1920s Egyptian fabric for Lady Lola.

While Lola and Annie shared photos from the bash on Instagram, Sienna firmly cemented her fashion icon status as she posed for a photo with Annie and Camille Charriere.

Sienna previously gave insight into her health and fitness regime, telling Vogue: ‘I do yoga three times a week… more because I’m just looking for some equanimity. It’s very easy to feel exhausted by these schedules and time zones.”

The New York-based actress said at the time that she was not a big fan of the spin class SoulCycle.

She said: ‘Sometimes I cringe a little at the motivational aspect of it, but that’s only because I’m English and we’re not used to saying, ‘You’re seeing your dream!’ Go get it”.

“Cooking is a focus for me,” Sienna shared, “but I wouldn’t say healthy… I’m more of a home cook: roasts, some Asian food, pastas and sauces and soups. In terms of, say, chia seeds and any grains, no. I’m like, ‘Fried eggs and Marmite toast.’
