Are there any good home care methods?

I recently started using a new beauty device!

Actually, I didn't buy it recently... I bought it a long time ago, but I didn't use it much because it was annoying, but I started using it again recently!

But there was a problem....

I've often seen reviews saying that this device can cause side effects like acne or pimples, but I didn't think that was the case...

I also used it a few times and suddenly started getting a lot of pimples ㅠㅠㅠㅠㅠ So I'm temporarily stopping...

I can definitely feel my facial lines being smoothed out right after using it, but I can't use it because I'm scared of getting pimples.

I think I need to find another home care method, but if you know of any good ones, please let me know.
