Moisturiser: Each and every one of you can attest to the fact a good moisturiser is a vital item in your beauty bag. I know from personal experience (and much experimentation) the most expensive does not necessarily mean the best for your skin type. Kate has obviously discovered this too. Kate has been spotted stocking up on Nivea Visage Pure and Natural at her local Boots store. The £5.10 moisturising day cream contains effective, organically grown natural ingredients.
Cleanser: According to Karin Herzog's UK managing director, Kate uses a number of the brands products. The Switzerland based brand is described as 'the original and the best, true oxygen based therapy, proven to deliver back to the skin oxygen, water and essential vitamins'. Kate uses the £33 Professional Cleansing Cream. The cleanser works to dislodge blockages in the skin, and when removed literally sucks out the dirt.
Face Cream: Kate uses the Karin Herzog Oxygen Face Cream. The product should be applied morning and night, to the face and neck without massaging into the skin. The cream is described as very well suited to younger users. It's non-oily texture means there is no oily residue left on the surface of the skin. It is £36 for 50ml.
Spot Zapper: To banish spots, cold sores, boils and blisters Kate uses the Karin Herzog Vita A Kombi 3. The acne cream is described as 'extremely effective'. It is £21.50 for the handy 15ml tube, which will easily fit into your purse.
Foundation: Kate chose to do her own make up for the royal wedding and reportedly uses Bobbi Brown Moisture Rich Foundation. The popular foundation provides SPF 15 sun protection while it hydrates skin. It is available in various shades for $46.
Concealer Pen: The YSL Touche Éclat Concealer Pen has been described as a 'miracle pen'. The $40 gold pen brightens around the eyes managing to erase fatigue.
Mascara: Kate is rarely photographed without her trademark black mascara and eyeliner on. To create the illusion of longer lashes Kate uses Lancome Custom Wear Volume Mascara. With its 1,000 sensor bristles, the brush delivers made to measure lash volume that you control with each sweep. It is available for £21.
Eyeliner: Kate uses the £16 Lancome Crayon Khol eyeliner to define the colour of her eyes.
Eyeshadow: To create the perfect smokey eye, Kate uses the Get In Line Smokey Eyeshadow and Stencil Kit. It is available for $36.
Blush: Kate uses the pale pink Bobbi Brown Blush to add a little colour to her cheeks. The formula glides on smoothly and offers a matter finish. It is $24.
Bronzer: To give her cheekbones a shimmer Kate applies the Bobbi Brown Shimmer Brick Compact. The brush on powder is $39.
Lips: Kate favours darker eye make up and balances the look out with a neutral lip. The Duchess wears the $23 Bobbi Brown Sandwashed Pink Lipstick with a layer of pale pink lip gloss.
Nail Polish: Kate wears Essie nail polish, mostly opting for pale pinks. However recently Kate has been experimenting with darker colours. Essie comes in all colours for $8 per bottle.
Perfume: Kate wore White Gardenia Petals by UK brand Illuminum for the royal wedding. It is described as 'As fragrant as a vase of white flowers, this is a delicate and refined perfume. The top not of Lily evokes a tropical seaside location, Amber wood underscores the light and capricious bouquet'. You can purchase the perfume for $140.
