Considering the constraints from collider experiments and dark matter detections, we investigate the SUSY effects in the Higgs productions e+e- → Zh at an e+e- collider with a center-of-mass energy above 240 GeV and γγ→ h → bb at a photon collider with a center-of-mass energy above 125 GeV. In the parameter space allowed by current experiments, we find that the SUSY corrections to e+e- → Zh can reach a few percent and the production rate of γγ→ h → bb can be enhanced by a factor of 1.2 over the SM prediction. We also calculate the exotic Higgs productions e+e-→ Zh1 and e+e-→ A1h in the next-to-minimal supersymmetric model (NMSSM) (h is the SM-like Higgs, h1 and A1 are respectively the CP-even and CP-odd singlet-dominant Higgs bosons which can be much lighter than h). We find that at a 250 GeV e+e- collider the production rates of e+e-→ Zh1 and e+e-→ A1h can reach 60 fb and 0.1 fb, respectively.
