We need blood, it delivers nutrients and removes waste. However, there is considerable evidence that during human aging, the network of the smallest blood vessels, microvasculature, atrophy with age. The research group in this paper reported that topical application vitamin C to the skin caused significant regression of senile purpura. For the sake of our mission to Renew the Rivers, we hope to see more research on the aging human microvasculature and what we can do about it.
