To improve our understanding of the mass loss in red supergiants (RSGs), it is of paramount importance to observe the wind acceleration region close to the star with high spatial resolution. I review the recent progress in milliarcsecond-resolution imaging of the surface and atmosphere of RSGs with optical and infrared long-baseline interferometers. The high resolution images of RSGs have revealed the true face of these behemoths, which have turned out to be very complex.
