오 좋은 괄사네요
I've been doing this for a long time too~ I think it's really good for reducing facial swelling.
The one I use is Face Factory's Rose Quartz Gua Sha.
I felt it was more effective because rose quartz itself has a cooling energy.
I find myself reaching for it more often than a regular gua sha tool because it's a roller type and requires less force.
