  The perturbative effective potential calculated in Landau gauge suffers from
infrared problems due to Goldstone boson loops. These divergences are spurious
and can be removed by a resummation procedure that amounts to a shift of the
mass of soft Goldstones. We prove this to all loops using an effective theory
approach, providing a compact recipe for the shift of the Goldstone mass that
relies on the use of the method of regions to split soft and hard Goldstone
contributions.
