"Snail slime can help the recovery of skin cells on the face, so we expect the snail facial to help heal damaged skin," Yoko Miniami, sales manager at Tokyo's Clinical Salon which offers the treatment, told the Sunday Telegraph.
The substance is also believed to help tackle sun damage, according to Ms Miniami.
"We are interested in the fact that snails have a function that can help heal skin damaged by ultraviolet rays."
According to Ms Miniami, the salon also uses creams infused with snail slime provided by the salon's five resident snails which are fed on organic vegetables, including carrots, spinach, Swiss chard and Japanese komatsuna greens.
Disgusting though it might sound, snail slime isn't a recent addition to the anti-ageing arsenal and was first used more than 2000 years ago.
According to records left by early doctor Hippocrates, crushed snails mixed with sour milk were used to treat skin inflammation, while more recently, products infused with mollusc slime have proved popular in Japan and South Korea.
Despite the long history of snail slime as a beauty treatment, the Clinical Salon's effort was apparently inspired by Mount Fuji's recent elevation to UNESCO World Heritage status.
Climbers are likely to suffer skin damage as they climb the peak, thanks to the thinner air and intense sunshine, and it is this the treatment is intended to fix.
