괄사하면 시원하지요
This is a gua sha that creates a V-line.
My face is on the rounder side, so I was really envious of people with a V-line. I heard that using a gua sha tool is good for facial care. I bought it at Daiso for 2,000 won.
I massage with a gua sha about 20 times before going to bed. I feel a sense of psychological stability compared to not doing it.
