The Ichthyotherapy is a totally natural system that basically consists of small suctions of the fish called GARRA RUFA that produce a pleasant comfort. These fish selectively exfoliate, and by removing dead skin cells, your skin will be cleaner. So, when you come to our fish spa in Fuerteventura you will notice that when the fish suck the dead skin they secrete DITRANOL. This is an enzyme containing ANTHRALINE, which stimulates the growth of new skin cells. Since they have no teeth, these fish (GARRA RUFA) remove dead skin cells by suction, leaving the skin clean, soft and healthy. All this makes for a great foot spa experience.
