Is there a good way to use Vaseline?

I happened to see an article introduced by a dermatologist and became curious.

I'm curious about how to use Vaseline properly.

I have heard that it is widely used for moisturizing dry skin, so I would like to know if it is okay to apply it to the face. I am also curious if there is a specific method to apply it effectively to particularly dry areas, such as the lips, hands, and feet.

I've also heard that applying a small amount to the ends of your hair helps with shine. Has anyone actually tried this?

I would appreciate it if you could share detailed tips on how to safely and effectively use Vaseline in everyday life.
