Inquiry regarding needle roller usage

Hello. I recently purchased a needle roller, and since it is my first time using the product, I have a few questions.

I would like to know the best way to care for my skin before and after use, as well as the recommended frequency and interval of use. I am also curious about products that are good to apply immediately after use, and whether there are any cosmetics or ingredients to avoid. Please also advise whether it can be used on the entire face and whether sensitive areas should be avoided.

I would appreciate it if you could inform me of how to maintain hygiene, as well as the cleaning and storage methods. I am contacting you because I would like to use the product more safely and effectively. Please reply. Thank you.
