Chapter 10: The Passenger - S2-E2
Factual error: The premise of the episode is that Mando needs to travel at sublight speed or else the fragile eggs will die. They need to travel to a nearby star system, though, not just a planet. Stars can't be too close together, so Mando is in for a trip that would take him literally years, which is not reflected at all by what is shown in the episode. (00:08:00)
Chosen answer: They could be just like wrinkles from age, like the elderly Togruta in the Zygerrian slaver arc in The Clone Wars series, as Ahsoka is considerably older than her animated appearances. I think there is probably a character design/stylisation aspect to it as well - the other Togruta we've seen in live action, Shaak Ti, has four segments or folds in her lekku that were not visible in her Clone Wars appearances, so it would seem the character design in Clone Wars and Rebels reduces such features.
