Glow girl: Mila Kunis joined Justin Timberlake at the Berlin premiere of Friends With Benefits today
Mila Kunis looked simply radiant at the German premiere of Friends With Benefits today.
And given her latest beauty splurge, it is little wonder.
The 27-year-old, who is currently on a European promotional tour with co-star Justin Timblerake, indulged a $7,000 facial last week at the salon of aesthetician to the stars, Scott-Vincent Borba.
The procedure, called the HD Diamond and Ruby Peel, uses precious stones including rubies and diamonds that work as antioxidants for the skin and, according to Mr Borba, create a ‘lustrous sheen.’
Speaking to American InStyle about the treatment, Mr Borba said: ‘I always do her skin, neck, décolleté, arms and the back of her hands, anything that will be possibly showing with her dress.’
Mila put the results on show today as she posed with Timberlake on the red carpet in Berlin.
She looked stunning in a blush pink silk cocktail dress by Lanvin and maroon Ferragamo pumps standing arm in arm with Justin, 30.
The pretty and feminine dress showed off Mila's long tanned legs and tiny waist.

Justin looked casual compared to her in dark jeans, a white shirt and black jacket which he paired with vintage looking black boots.
The also posed with the film's director Will Gluck who was also dressed in a casual fashion in jeans and a black long-sleeved T-shirt.
The couple have been busy travelling the globe promoting their new film which was released in the U.S two weeks ago.
While she seems comfortable showing off some skin on the red carpet, Mila has certain rules regarding what she will flash in front of the camera.
In an interview with Ryan Seacrest his Kiss FM radio show, she discussed the process of casting a lookalike body double to use in the sex scenes for the raunchy film.
These young ladies came in and they were in a casting room with the director and the casting director and my make-up artists,' she recalled.
'These lovely women had to show us their derrière and we chose the one that resembled my body the most without looking like it is fake.'
