Simon Cowell shows off his smooth visage at 13th AGT final

He has been an America’s Got Talent judge since its inception in 2006.

But Simon Cowell showed minimal signs of aging as he marked his 13th final of the hit variety show inside Hollywood’s Dolby Theatre on Wednesday night.

The 58-year-old star, who admitted undergoing a non-surgical facelift, earlier this year, displayed a seriously smooth visage as he and fellow judges Mel B, Heidi Klum and Howie Mandel watched magician Shin Lim take the crown.

Flashing his trademark pearly whites, Simon’s complexion positively glowed as the star walked the red carpet before taking his seat on the panel. 

Earlier this year, the X Factor judge, who’s on TV screens all year round thanks to his numerous talent shows, admitted he had undergone a non-surgical ‘sewing bioplastic-infused thread’ facelift after having years of Botox.

The music mogul told The Sun on Sunday in May he had splashed out £2,000 on the treatment, which he also confessed was incredibly painful.

The TV personality is said to have visited cosmetic surgeon Dr Jean-Louis Sebagh, known as the ‘Picasso of dermatology’, for a Silhouette Soft Lift, which promises to create a more ‘youthful’ appearance. 

Simon revealed: ‘There’s lots of things you can do now, you don’t just have to stuff your face with filler and Botox. 

‘It hurts like hell but it gets rid of sun damage and unplugs all the c**p. For me now, it’s all about having clean skin, if you have clean skin, you look better.’

The method (also known as a ‘one stitch face lift’) uses an absorable thread with cones to lift the facial skin and encourage collagen production. The unwanted excess skin is pulled back by the underlying muscle.

The threads are ‘stitched’ on to the neck, brow or mid-face and promise to create a fresher, more youthful appearance.

Last night’s final saw British schoolgirl Courtney Hadwin narrowly miss out on being crowned the winner of America’s Got Talent and a $1million prize.

Despite getting knocked out earlier than expected, judge Simon was full of praise for the teenage sensation. 

He said: ‘I always say the most important part of being a star is being remembered and that’s what you do. Every time you perform, people are going to remember you.

‘You are going to inspire people. You are going to tell a whole new generation of people what rock and roll is all about. All these great songs.

‘So you are more than a great singer, you are like a trendsetter. Without people like you, we don’t look good.’
