How do you use mist?

My skin has been dry lately, so I've been spraying mist frequently. I'm wondering if using mist often really helps.

I've heard that spraying mist too often actually makes things dry. Is that true?

I would also like to know how often to use the mist and the correct way to use it.

Also, please let me know of some cost-effective mists that are good for dry skin types to use in winter.

thank you
