The user can close minor to moderate wounds near-instantaneously, appearing as though they never happened, with more serious injury taking more time to heal, regardless of the extent of the damage. Depending on the severity of the injury, the process of healing from more grievous wounds can span from a few seconds or minutes to a matter of hours. Lost or damaged limbs, internal organs and damaged nerves can be completely regenerated, and fatally damaged cells can regenerate, preventing scars.
They are near-completely unaffected by toxin or drugs and their cellular senescence is drastically reduced, if not completely halted, granting them decelerated aging/eternal youth.
User can regenerate as long as the head/brain is damaged to no more than a certain level, leaving destruction of the head as one of the few sure methods to ensure their death. Their healing strength may be so powerful that their blood could be enriched with healing powers that can be used to heal others.
