If you spend much time reading blogs, you’ll know that ‘strobing’ is a buzzword right now: the clever use of light and shade to make skin look its radiant best. This taps right into that trend – for body skin. Now, we have it on fairly good authority that the late Princess of Wales – a gazelle-limbed beauty, if ever there was one – used to lengthen the appearance of her legs by smoothing a shimmer the length of her shins. This is designed to do exactly that (and add a touch of gleam to shoulders, forearms, too).

It’s also moisturising in its own right, with hyaluronic acid, aloe vera and algae extract, which – along with the light-diffusing powders and natural caramel – deliver a glossy and realistic sheen. (You dispense via a flat roll-on, then blend with fingers.) There’s also a lovely, This Works-ish aromatherapy scent (although we don’t imaging you spend much time sniffing your shins, except possibly in a yogic forward bend).

This is probably never going to make it onto anyone’s list of ‘beauty essentials’– but it nevertheless does what it says on the rollerball.
