Recent precise parity-violating electron scattering experiments on $^{48}$Ca(CREX) and $^{208}$Pb (PREX-II) provide a new insight on the formation ofneutron skin in nuclei. Within the energy density functional (EDF) framework,we investigate the implications of CREX and PREX-II data on nuclear mattersymmetry energy and isovector properties of finite nuclei: neutron skinthickness and dipole polarizability. The weak-charge form factors from the CREXand PREX-II experiments are employed directly in constraining the relativisticdensity-dependent point coupling EDFs. The EDF established with the CREX dataacquires considerably smaller values of the symmetry energy parameters, neutronskin thickness and dipole polarizability both for $^{48}$Ca and $^{208}$Pb, incomparison to the EDF obtained using the PREX-II data, and previouslyestablished EDFs. Presented analysis shows that CREX and PREX-II experimentscould not provide consistent constraints for the isovector sector of the EDFs,and further theoretical and experimental studies are required.
