This is the exfoliator I use.

This is a peeling device I bought on Coupang a few years ago. I use it about 1-2 times a week, and it hasn't broken down and is still working perfectly fine haha. It's convenient to use because you just charge it, and it's lightweight. It seems to have other functions besides exfoliation, but since I only use it for that, I'm not really familiar with the others. I don't use it often because I'm worried it might irritate my skin. It's affordable, so it's great for casual use hahaha.
