Its hard to date because I look to young?

I've been trying to get a girlfriend these past few months, but they always treat me like a little brother. The last girl I talked to said I look too young, and it's driving me crazy. When I remove my beard, I look like a 14-year-old boy. Even with a beard, I barely look 18 since I don't have a full beard. Is there a way to look more mature? I've been hitting the gym to lose the baby fat on my face.
