  In this article I review the origin and the effects of chirally enhanced
loop-corrections in the MSSM based on Refs. [1-3]. Chiral enhancement is
related to fermion-Higgs couplings (or self-energies when the Higgs field is
replaced by its vev). I describe the resummation of these chirally-enhanced
corrections to all orders in perturbation theory and the calculation of the
effective fermion-Higgs and gaugino(higgsino)-fermion vertices. As an
application a model with radiative flavor-violation is discussed which can
solve the SUSY-CP and the SUSY-flavor problem while it is still capable of
explaining the observed deviation from the SM in the Bs mixing phase.
