[Purchased with my own money] Gua Sha

I went to Daiso and bought a gua sha, and I'm using it well. I've noticed a lot of people using gua sha these days. Apply massage cream or oil, massage for about 5 minutes, and then take a long break. I heard it can irritate the skin. I plan to keep at it diligently. I hope my jawline becomes a V-shape.
