Since receiving professional lessons from London-based make-up artist Arabella Preston for the royal wedding, the Duchess of Cambridge personally takes care of her beauty regime.
So we're sure Kate knows exactly what essentials she'll need in her make-up bag to look as fresh and chic as ever on the 10-day tour that begins on Tuesday.

As with all long-haul flights she will need to keep her skin well hydrated throughout the journey to maintain a perfect base for make-up.
Karin Herzog's oxygen-infused skincare items are said to be a regular in Kate's daily regime. And the Karin Herzog Oxygen cream (£36) will detox and regulate the skin's oils – even at high-altitude – to keep her skin radiant and glowing.
For light but flawless skin Laura Mercier is said to be a favourite of the young royal. Laura Mercier Oil-Free Tinted Moisturizer SPF 20 (£33) alongside a base of Laura Mercier Oil-Free Primer (£28) will provide a long-lasting finish perfect for a warmer climate.
Water resistant products are ideal for tackling humidity without the need to re-apply.
Bobbi Brown cosmetics include the Dark Brow Kit (£35), Long-wear Gel Eyeliner (£17) and Creamy Colour for lips and cheeks (£12.50).
Hot climates often leave hair unruly and unkempt looking.
To keep her tumbling curls under control and super shiny Kate should use one of her favourite brands, Kératase.
But she needn't worry about her hair as new personal hair stylist Amanda Cook Tucker will be at hand to create the perfect blow-dry.
Having previously styled Kate's locks at home, Amanda will travel with the royal couple throughout the tour.
We expect half-up, half-down tresses, beautifully braided buns and sophisticated chignons that will keep her hair looking great and in place.
