There are some weird and wonderful things inside your anti-ageing cream that you might not know about - in fact this one is really rather deadly.

The makers of Planet Skincare anti-ageing daily moisturiser - a jar of face cream made with the venom of an Asian snake - claim their synthesised viper venom 'stuns' the skin in the same way a real snake bite would, helping to keep it smooth.

The 60 cream, which has become a bestseller in the UK, gives 'Botox-like results' without needles. It claims to reduce the appearance of crow's feet and fine lines when massaged into the skin.
