There's a lot of debate about whether using a separate mist is good or bad. What is the correct answer?

Lately, I have been wondering if I need to use a separate mist product.
There are times when I feel dryness even though I think I have already applied enough foundation.
I was wondering if using a mist would be helpful in times like this.
I would also like to know if it simply provides temporary hydration or if it actually has any significance for the skin.
I hear that it is often used over makeup, so I am curious about its effects.
I am actually hesitant because I've heard that my makeup might fall apart.
I am also confused about whether using mist frequently is a good habit for my skin.
I am worried that I might be adding unnecessary steps for no reason.
I am curious about the criteria for when a mist should be used and when it should not.
