Exercise your masseter muscles more, dear. Because you chew more, your masseter muscles will develop and your face will look more round. Don't choose foods that are too hard. But be sure to chew and drink porridge and fruit and vegetable juice. Why can you lose weight? Not only because the fiber is thick and easy to plump, but also because you don't exercise your face, even your face will lose weight soon.
Thin face, very photogenic, baby. But if you want to make your face more attractive, it will definitely look better. I wish you an early realization of your wish.
