  We exploit a recent computation of one graviton loop corrections to the
self-mass [1] to quantum-correct the field equation for a massless, conformally
coupled scalar on a de Sitter background. With the obvious choice for the
finite part of the $R^2 \phi^2$ counterterm, we find that neither plane wave
mode functions nor the response to a point source acquires large infrared
logarithms. However, we do find a decaying logarithmic correction to the mode
function and a short distance logarithmic running of the potential in addition
to the power-law effect inherited from flat space.
