When is it normal for girls to usually lose their baby face/baby fat?

I hate it so much. I’m supposed to be 15 but my face makes me look 12 and being short doesn’t help either.

I don't know if it’s genetic cause my moms in her 40s and still has a “baby looking face”. I’ve tried to do facial exercises but they don’t really help much. I’m thinking of buying a Gua sha & jade roller cause I’ve seen people get results with those but if anyone can give me advice it’d be appreciated.
