Sienna Miller shares skin secrets following Glastonbury and Wimbledon appearances

Sienna Miller revealed how she achieves her glowing appearance in a new selfie shared on Instagram on Wednesday following her Wimbledon and Glastonbury appearances.

The British actress highlighted her flawless skin while posing with celebrity facialist Shane Cooper, who revealed the secret to her glowing skin at 42.

Explaining the bespoke treatment she had, the skin expert captioned the images: “Adore @siennathing. As a long-term client, it’s always nice to catch up during her regular session.

“Today she had the exclusive facial, including the neck and décolletage. Just look at her glow after the treatment!

“Sienna has the @shanecooperskincare at home to maintain that glow.”

The Hollywood star underwent a 90-minute treatment which starts by removing dead and dull skin cells, using a personalised exfoliation that penetrates active ingredients into the deeper layers of the skin stimulated by C02 micro-bubbles to oxygenate.

The bespoke facial then uses micro-currents, and tri-polar radio-frequency, all designed to promote collagen production, tighten skin, and reduce wrinkles. It also featured medical LED phototherapy to promote maximum cell activation and lymphatic drainage to remove unwanted toxins and inflammation.

Cooper, whose clinic is based in South Kensington, is no stranger to tending to A-listers skincare needs regularly treating celebrities like Oscar nominated Barry Keoghan, Love Island host Maya Jama and Bridgerton star Phoebe Dynevor.

Miller’s latest appearance comes following a busy few weeks for the star, having been spotted attending Glastonbury earlier this month and in the royal box at Wimbledon as the quarter-finals got underway.

In May, Miller attended the premiere of her film Horizon: An American Saga at the Cannes Film Festival, accompanied by her boyfriend Oli Greene and her daughter Marlowe.

The outing marked Marlowe's first-ever red carpet appearance, with the actress previously only showing her daughter’s face in a Vogue shoot in July 2020.

The 42-year-old actress shares her 11-year-old daughter with ex-partner Tom Sturridge, with whom she was in a relationship from 2011 to 2015.

Miller recently welcomed her second daughter and first child with Greene, 27, in January.

Last month, the Burnt star discussed the age gap between her and partner Oli Green, who is 15 years her junior, in a recent interview.

She told Harper’s Bazaar UK: “I didn’t expect to take it seriously and then quite quickly, I fell in love.

“I wasn’t like, ‘I’m gonna get a younger boyfriend.’ It was more, ‘F***! Why are you young? That’s so annoying.’”

Adding: “There is a difference in the way that generation of men respect women. It’s specific to him, he is very wise and well-adjusted, but I do believe it’s also that generation.

“They have grown up with a slightly more level playing field. I see it in his female friends as well as in the men.”
