What are some good beauty devices to use instead of a dermatologist?

Are there any good beauty devices suitable for home care?

I felt like going to a dermatologist would be too expensive,

Are there any good beauty devices that allow me to do convenient home care and achieve dermatologist-quality results without visiting a clinic?

Is the LG Prael Super Foam Thermashot Ultimate Beauty Device a good product?

I thought if I'm going to use a beauty device, it would be better to buy a reliable one...

Please recommend a good beauty device that really delivers results!

Are Medicube or Centellian24 brands good too?

Also, do beauty devices have different effects depending on the product?

There are some that are surprisingly expensive and some that are cheap, so I'm having a hard time deciding.
