The rise of a star

Sienna has been busy lately making her second season debut at London Fashion Week and working on her subsequent on-off-now-apparently-on relationship with her co-star, Jude Law. Despite the ongoing ups and downs of her love life, it has really been her bohemian turned edgy wardrobe and barely-there make-up which has us all captivated. We\'ve had a rummage in her beauty bag to find out which products the star can\'t live without...

Going au naturel

Sienna is often snapped strolling along an exotic beach or sunbathing on a yacht somewhere so she\'s always careful to stick to products that contain a high SPF to protect her skin against sun damage. Susan Posnick Colorflo is a mineral-based, SPF 26 foundation containing a unique light-diffusing formula. Containing gentle ingredients this foundation has a huge celebrity and make-up artist following thanks to its flawless finish and sweat-proof, water-resistant formula. Perfect for sun worshippers like Sienna.

New beginnings

Sienna was recently signed as the new face Hugo Boss\' latest offering, Boss Orange, out this month. Boss Orange is the brand\'s first ever signature fragrance which Sienna describes as \"musky, sweet and sexy.\" Thomas Burkhardt, GMD for Hugo fragrances says Sienna was the ideal choice as the new representative because she is a \"liberated soul - light-hearted, spontaneous and passionate - and she quite simply wears her heart on her sleeve.\" Couldn\'t have put it better ourselves!

From £26, nationwide

Naturally refreshing

Sienna has been spotted working up a sweat in a leather catsuit on set of her latest film, GI Joe: The Rise Of Cobra. To help keep her refreshed Sienna sticks to using Korres\' refreshing Basil Lemon shower gel, a green and spicy gel which has a great lemon zest aroma. She is also a huge fan of Korres Sunflower extract shampoo for coloured hair which is clinically proven to protect hair colour three times more efficiently than traditionally used products.

Going nude

When Sienna had her nails painted in this nude shade from OPI on a photo shoot she immediately requested a bottle to take away with her. Nude is summer\'s new black and the muted tones look set to carry on well into autumn/winter so pick up a bottle of Sienna\'s favourite Sand in my Suit shade ahead of the rush.

Lay back and relax

A gruelling work schedule coupled with one too many late nights can play havoc with a girl\'s skin so Sienna keeps hers in check and stops breakouts before they happen by having regular facials at Elemis\' day spa. She\'s a particular fan of Elemis Visible Brilliance Facial which involves three key Elemis products; Elemis\' Pro-Collagen Marine Cream, Papaya Enzyme Peel and Cellular Recovery Skin Bliss Capsules. Smooth on the Marine Cream to stop wrinkles in their tracks and boost moisture levels. Give skin a boost with the Cellular Recovery Skin Bliss Capsules which contain the highest concentration of Anti-Oxidant power to help repair the visible signs of ageing and counteract the damaging effects of everyday pollution and smooth on the Papaya Enzyme Peel twice a week to exfoliate skin leaving it silky smooth and soft.

Elemis Pro-Collagen Marine Cream is priced £75, Cellular Recovery Skin Bliss Capsules are priced at £58, Papaya Enzyme Peel, £26, timetospa.co.uk

Eyes wide open

Eyelash curlers can make a world of difference to your look and when Sienna needed to get that sex kitten look in Alfie she stuck to using Suqqu\'s renowned eyelash curlers. Unlike many other eyelash curlers these babies produce long-lasting curl in record-time, great for girls-on-the-go.

In the detail

Sienna always keeps her make-up looking natural, playing up her eyes with a simple flick of eyeliner to complement her boho look. She\'s a devotee to Bobbi Brown\'s Long-Wear Gel Eyeliner which has all the drama of a liquid liner but the ease of application of a pencil. Line on using a fine brush and finish with a flick at the corners to create Sienna\'s Factory Girl look.

Fresh and fragrant

When Sienna needs a quick pick-me-up she spritzes on Jo Malone\'s iconic Lime Basil and Mandarin Cologne which has a great zesty fragrance intermingled with the subtle scent of peppery basil and aromatic white thyme.

A list beauty bag celebrity make up sienna miller fake bake

OK, so the many holidays Sienna seems to take probably help to maintain her permanent sunkissed look but as every beauty savvy girl knows, exposure to the sun will cause premature ageing and that unsightly leathery look. Sienna instead regularly smooths on the iconic fake tan, Fake Bake for a natural glow and healthy skin all year-round.
