Learn Farsi: در این آرایشگاه، تا چه حد به طراوت پوست رسیدگی می‌شود؟ - In this beauty salon, to what extent is the skin's freshness attended to?

This is the core of an impersonal passive. The active verb is رسیدگی کردن به (to attend to). Unlike English, Farsi doesn't let the object of a preposition become the subject of a passive sentence. Instead, the preposition به stays right where it is, and the verb is fixed in the third-person singular (رسیدگی می‌شود). You can think of it literally as "to the skin's freshness, attention is given."

Is رسیدگی a noun or part of the verb here?

Both! The active compound verb is رسیدگی کردن. In the passive voice, the auxiliary verb شدن replaces کردن. So رسیدگی (a noun meaning "attention" or "care") acts as the non-verbal half of the passive compound verb رسیدگی می‌شود.

How does تا چه حد literally translate to "to what extent"?

The word حد means "limit," "boundary," or "extent." The phrase literally means "until what limit." It is the most natural chunk for expressing "to what degree" or "how much" when asking about the scale of an action at this level.

Does رسیدگی کردن only apply to beauty, pampering, and personal care?

Not at all. While it means "attending to" or "caring for" in this context, its most common meaning in news or formal contexts is "to investigate" or "to process" (like a court case, a customer complaint, or an application). It generally means dealing with something that requires active, ongoing attention.
