I recommend Gua Sha.

I use a gua sha as a beauty accessory.

I use it a lot when my face is swollen.

It wasn't noticeably visible, but it still went down faster than not doing it.

I purchased the Lallabadi Gua Sha Go for around 29,000 won, and since it is made of ceramic, it feels nice to touch the skin smoothly without any resistance.
