Cryogenic detectors are excellent devices for rare event searches. Thanks to their low energy thresholds, these detectors are at the cutting edge for the investigations of light dark matter (DM). The CRESST (Cryogenic Rare Event Search with Superconducting Thermometers) experiment explores with high sensitivity the parameter space of low mass DM candidates, being the pathfinder in the sub-GeV/c$^2$ mass range. CRESST employs scintillating CaWO$_4$ crystals as target material operated at mK temperature. Thanks to the simultaneous read-out of heat, in the main absorber, and light, with an auxiliary cryogenic light detector, the background in the region of interest is strongly suppressed. In 2018, the first stage of CRESST-III data taking was successfully completed, achieving an unprecedented energy threshold for nuclear recoils, lower than 100 eV. New results of CRESST-III will be presented accompanied by a status update on the ongoing activities.
