My beauty accessory is a gua sha.

To be honest, I'm not very good at beauty treatments, so I'm not good at using eyelash curlers or anything like that. But I happened to see a colleague sitting next to me always using a gua sha, so I found out about it and bought one to try it out. It's absolutely great. I never thought it would be good for beauty purposes, but it seems to improve my complexion, so I'm extremely satisfied with this accessory. I don't wear much makeup, but my skin looks great.
