  The constraint on the ADD model of extra dimensions coming from photon
annihilation into Kaluza-Klein graviton in supernova cores is revisited. In the
two photon process for a conservative choice of the core parameters, we obtain
the bound on the fundamental Planck scale $M_* \gtrsim$ 1.6 TeV. The combined
energy loss rate due to nucleon-nucleon brehmstrahlung and photon annihilation
processes is rederived, which shows that the combined bounds add only second
decimal place to $M_*$. The present study can strengthen the results that are
available in the current literature for the graviton emission from SN1987A
which puts a very strong constraints on models with large extra dimensions for
the case of $n=3$ .
