Fans and experts criticize Kylie Jenner's new walnut face scrub before it's even launched

Kylie Jenner might be the queen of beauty right now – but for the first time she is facing a big back lash over her products. 

The beauty guru's line is set to launch on 22 May, but already one item is concerning fans online - a face scrub that contains walnut, going at $22 (£17).

Kylie advertised the scrub on Twitter and Instagram, where she hailed it as her 'secret to a fresh face,' adding it could be used every day.

But fans and skincare experts hit back, claiming that using a walnut scrub daily can leave micro-tears in the skin, causing premature ageing.
