I've been wondering this, too, and remembering back to childhood when my mom advised always moving from extremities inward towards the heart (sunscreen, toweling off, etc).
Isn't that because moving away from the heart would force blood back against venous valves, possibly doing damage to them?
You could test this by comparing people who wet shave daily with those who don't. Lathering on the skin during wet shaving delivers an incidental massage.
For aestetics little to none, for overal health and bloating probably better than with think but not as much as we'd like
