Jiri Prochazka without a beard looks like a significantly different appearance compared to how he appears at the present time.
Beards are a form of facial hair that is considered a makeup for males. Their entire facial structure takes on a distinctively new appearance once the beard is shaved off. A person’s jawline can also be made to look stronger and more defined with a beard.
A strong jawline would actually make a fighter more likely to win because it would create more leverage for the punch against the rest of the skull, generating higher vibrations in the brain. This would make it more likely that the fighter would win. The beard has little use other than to obscure the appearance of the chin.
