Motivated by the excesses around 95 GeV observed in the diphoton and bbˉ data, this study focuses on investigating these two excesses within the framework of the B−L supersymmetric model (B-LSSM), due to the existence of two light Higgs bosons in the model. Considering the two-loop effective potential corrections, it is found that the B-LSSM is hard to fit the 125 GeV Higgs signal strengths and the two excesses around 95 GeV in the experimental 1σ intervals, while the model can reproduce them in the experimental 2σ intervals simultaneously. And considering the two loop effective potential corrections to the squared Higgs mass matrix is important to account for the mixing effects among Higgs sector.
