  In a class of supersymmetric flavor models predictions are based on residual
symmetries of some subsectors of the theory such as those of the charged
leptons and neutrinos. However, the vacuum expectation values of the so-called
flavon fields generally modify the K\"ahler potential of the setting, thus
changing the predictions. We derive simple analytic formulae that allow us to
understand the impact of these corrections on the predictions for the masses
and mixing parameters. Furthermore, we discuss the effects on the vacuum
alignment and on flavor changing neutral currents. Our results can also be
applied to non--supersymmetric flavor models.
