Light singlino-like neutralino is found to be a very promising candidate for DM in the allowed parameter space of the NMSSM. The DM annihilation process takes place via light Higgs bosons which are natural in this model. Identifying the allowed region of parameter spaces including various constraints, the detection prospect of such light DM candidate and Higgs bosons are explored at the LHC with its high luminosity options. Light Higgs bosons and the DM candidate, the lightest singlino-like neutralino are indirectly produced at the LHC via the SM Higgs production and its subsequent decays. Jet substructure techniques are used to tag boosted Higgs. We observed that a reasonable signal significance, more than 5$\sigma$ can be achieved corresponding to integrated luminosity options ${\cal L}=$300 $\rm fb^{-1}$ and 3000 $\rm fb^{-1}$, for the range of Higgs bosons and neutralino masses compatible with low mass DM solution.
