Low-mass dielectrons are an important probe for the hot and dense medium which is created in ultra relativistic heavy-ion collisions. Since leptons do not interact strongly, they carry information from all collision stages with negligible final state interaction. While pp collisions provide a reference measurement for a medium-free environment, the impact of cold nuclear matter effects on the dielectron characteristics can be estimated from p-Pb collisions. In this poster the latest results of the dielectron measurements in minimum bias p-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV with the ALICE detector are presented. The measured dielectron mass spectra will be compared to expectations from hadronic sources.
