We examine the relic density of the light mass dark matter region in the inert doublet model (IDM) when the dominant process is due to co-annihilation between the lightest neutral scalars of the model.

The theoretical uncertainty brought by the scale dependence leads us to introduce a new criterion on the perturbativity of the IDM.
