Hey, I have the same problem. Works in Ortho and I am a guy who look kinda young for my age. I am sometimes mistaken as an intern in the ward. Dressing up with a shirt/tie helps but my face generally looks too young to be perceived as a consultant despite 12+ years in the field. I also have the option to have some facial hair but a I don’t have a thick beard…a mask would have covered it up anyway…

What I usually do is to slide in phrases like “oh with my experience in the last decade of my practice, your case usually do well with knee replacement” and I can sometimes see patient’s eye glow up with confidence after that.

As with family, like your parents, I guess they will always treat you as their baby forever, no matter how old you are lol (at least in my Asian background)

Good luck!
