Ah yeah I forgot to note this kind of stuff:

Cyro grenades and cyro turrets do stops zombie's regenerating buff from healing and also deals DoT damage.

Concussion, on the other hand, stop zombie' regen as well but also will buffer up your DoT damage if any applied.

If you frozen a zombie and stunned with concussion at same or during freeze time or the versa, you might see that the cyro DoT not applied at all. But by the end of the stun debuff, the zombie will be immediatelly hit with total DoT damage buffered. Of course the regen does not buffered at all and it will starts regen again few ticks after the last debuff expired. Making either you freeze or stun zombies with regen buff to stop them from regenerating
