What you say is true, true confidence comes from acceptance within but it's difficult to be content if you are a perfectionist. Look at many of the greatest artists in history, they were very self critical and a masterpiece to the artist might not be as beautiful since sometimes beauty is in the eye of beholder.
However beauty is not completely subjective in all matters, of course there are trends and fashions of each culture that are considered as more desirable to the opposite sex and people will tend to learn towards these standards.
If growing facial hair and packing on thirty pounds of muscle gives the OP more confidence, I would tell him to go for it but not to abuse anything without consulting a general practitioner. I definitely feel more confident with a beard or goatee as I think it makes one appear more wiser or mature.
