The inverse seesaw mechanism provides an attractive approach to generatesmall neutrino mass, which origins from a tiny $U(1)_L$ breaking. In thispaper, we work in the supersymmetric version of this mechanism, where thesinglet-like sneutrino could be an asymmetric dark matter (ADM) candidate inthe maximally $U(1)_{L}$ symmetric limit. However, even a tiny $\delta m$, themass splitting between sneutrino and anti-sneutrino as a result of the tiny$U(1)_{L}$ breaking effect, could lead to fast oscillation between sneutrinoand anti-sneutrino and thus spoils the ADM scenario. We study the evolution ofthis oscillation and find that a weak scale sneutrino, which tolerates arelatively larger $\delta m\sim 10^{-5}$ eV, is strongly favored. We alsoinvestigate possible natural ways to realize that small $\delta m$ in themodel.
