  In this letter we investigate the role of regular (curvature
singularity-free) black holes in the framework of UV self-complete quantum
gravity. The existence of a minimal length, shielding the trans-Planckian
regime to any physical probe, is self-consistently included into the black hole
probe itself. In this way we obtain to slightly shift the barrier below the
Planck Length, with the UV self-complete scenario self-consistently confirmed.
