Biohealbo Probioderm Gua Sha is awesome!

Olive Young sells a variety of gua sha tools, but

I chose the Biohealbo product that my favorite YouTuber uses. Haha. I tend to have severe swelling when I wake up in the morning, but if I massage from the center of my face outwards, my facial muscles relax and the swelling definitely goes down. Also, it is easy to clean and seems much more hygienic than wooden gua sha tools!
