Corrected entry: When Cain arrives on the trash planet, his wounds, which Todd inflicted, are fully healed and well-scarred over, yet Todd has only been on the planet for a short period of time, not enough for the scars to appear.

Correction: As is stated in the beginning of the movie during the "demonstration" scene, these new soldiers were not born, but rather created using "DNA manipulation and gene recombination, resulting in quicker response time, better hand-eye, etc..." - It would stand to reason that these new soldiers would also heal faster, or all that extra speed and skill would be for nothing.
