your face is not tied to BF as much as it is to water retention and estrogen . you can have a low BF% , be on cycle and have elevated estrogen and have a round and puffy face because of it.
the guy in the pic is probably 10-11% bf , and appears to be holding water . I'd guess his estrogen is elevated as well.
Mike O'hearn does not get a bloated puffy face due to elevated estrogen , cause he is all natty
he also cycles his diet and runs a calorie deficit a lot of times during the year , which will thin the face
