I know it might sound dumb but hear me out.

Hi girlies. So I'm a chubby 20F who has never worn makeup in her life except putting on some mascara and tried on a few lip combos. I have my college annual day coming up in 5 days. Like i said I'm a bit chubby so I have a double chin and full cheeks, been using gua sha and I can say it did do the slightest change (wasn't expecting much so I'm satisfied it worked). Now the thing is I wanted to try contouring my face for the big day. The jawline, double chin mainly. And maybe cheekbones too if it works. I don't have any makeup products but I do have some brown lipliner and non sticky kajal. Can I do

something with them? If yes, how.
