Are beauty devices as effective as actual professional treatments?

There are so many advertisements for beauty devices these days, so maybe that's why I keep finding myself drawn to home care devices haha. Going to a dermatologist or aesthetic clinic every time is expensive and hard to find the time, so the fact that I can conveniently take care of my skin at home feels really appealing.

But now that I'm actually looking to buy one, the device price is quite steep, and I have doubts about whether it's as effective as professional care. The advertisements claim that pores tighten and elasticity is restored after just a few uses, lol. Can low-power devices used at home really replace hospital lasers or professional equipment?

Some people recommend it, saying that if you use it consistently, you can definitely feel your skin texture improving and your complexion brightening. Is that really true?
