Do beauty devices really work?

I have become interested in beauty devices because a wide variety of them have been released for home care recently. I am curious if consistent use of a beauty device actually helps improve skin elasticity, lifting, and texture. I would also like to know if there is a significant difference in effectiveness depending on usage frequency and method. I would like to know if it is suitable for sensitive skin or beginners, and if there are any side effects. Finally, if there are any essential criteria to check when choosing a beauty device, please share your detailed opinions.
