According to the manufacturer, Revitol’s hair removal cream seeps into the hair follicle and dissolves the hair at its root, as opposed to other creams, which cut the hair off at skin level.
This means that after a few uses the hair should grow back slower and lighter (Revitol claim that with between 1 and 4 months of use you should see a difference, and that “most people report hair stops growing with ongoing maintenance”).
The cream is applied to the skin and wiped off after 5-7 minutes (no longer than 20 minutes). When you wipe the product off with a towel or cloth the treated hair should come away too, leaving the area hair free.
