Is there anything that can be done to lessen facial asymmetry at a young age? Or is it all preprogrammed in DNA?

Looking back at my childhood yearbook photos, I noticed that about age 13, at the start of puberty, my face suddenly got really lopsided. My parents like to say it was because I slept face down as a child. But I didn't have noticeable asymmetry pre-teens, judging from my childhood photos. And during my teens, I slept face up. I envy those who look almost the same in their mirror images. Is there medical science to control asymmetry during growth? Just thinking about my future kids.
