How is a mosquito proboscis physically capable of puncturing human skin?

Human skin should be way too dense and strong for something so small and fragile like a mosquito. How is this possible?

It uses two maxillas to cut its way into the skin so the fascicle can enter while the labium remains on the surface of the skin.

Think two little rotary saws that cut their way into you while a syphon gets slowly lowered down. 

Its not even a puncture at the scale the mosquito is working at.
