Can filler give you a baby face and chubby cheeks?

I use to have chubby cheeks as a teen as I’ve gotten older the bottom half of my cheeks has lost volume I want this back , is it possible to inject filler in the lower half of the face to give the face a fuller appearance. I’ve had filler injected in my cheek bones but this gives my face a more defined look and makes me look even more gaunt . I’m average weight but I struggle to gain weight in my face so I look gaunt. If it helps I am 27 years old
