Gua Sha Vaseline Hack

I saw this hack on TikTok and basically the person put some Vaseline on their cheek-bones to jawline and they massaged it in with the Vaseline tin... (not the tubs, sorry!). I thought it seemed a bit weird but I can say the Vaseline tin is really smooth. Apparently it does work and gives you a better jawline if you rub it there. I tried it and I guess you could use it for a massage? Let me know if anyone has tried it before, and if you are going to, let me know the results!
