It's her jutsu to keep herself young. Once her chakra depletes she dies if she has lived long enough.
I have theorized that the older her body gets the more chakra she has to use to keep her body young.
"Wrinkles be gone, Boobs be on"
You would think having to constantly keep up that appearance would end up shortening her life too. Especially the older she gets. Apparently thats not the case though. Who needs Sasukes Rinnegan immortality when you have ol granny Tsunade's patented "Wrinkles be gone, Boobs be on"
Only her regeneration jutsu depletes her lifespan.
Tsunade is the only known user though, could be her own jutsu.
We can also assume that she's a lot weaker in her real form, as she's an old lady. She has to keep herself young if she wants to be able to fight.
Tsunade looks hotter than ever. Too bad shes still a virgin.

Her transformation is only an illusion, it isn't boosting her physical condition. This is why her feats against Madara are so impressive.
No, her jutsu actually makes her body young. A young body has better physical capabilities than her real, old woman form.
If this wasn't the case she would've let the jutsu wear down versus Madara.
So it's not an illusion, it only wears off when she runs out of chakra. The older her body is the more chakra she has to use to keep the jutsu running.
Tsunade is immortal
And she looks so awesome plus i have noticed shizune also looks younger
