Among beauty devices, how is a high-frequency galvanic skin care device for exfoliation?

I haven't used a beauty device before, but I saw advertisements on home shopping channels and the internet.

Besides expensive products, there are many affordable high-frequency galvanic skin care devices available.

There are options in the 100,000 or 50,000 won range, and I heard that the product descriptions are effective for exfoliation as well.

This is my first time using a beauty device, but looking at the reviews, it seems to be quite effective.

Would the recommended products or slightly cheaper options also be effective?

Since it's my first time using it, would it be better to buy an entry-level product rather than an expensive one?
