Ionithermie is a cosmetology treatment performed in spas, intended to remove cellulite using electrical muscle stimulation combined with a lotion made of algae, seaweed extracts and amino acids. [1] [2] The lotion is mixed with clay, and electrodes are placed on the clay to enact iontophoresis. [3] The specific materials vary from treatment provider, [2] such as including guarana extract, [1] and the results are generally small. [4] It uses direct current and is similar to another cellulite electrotherapy treatment called galvanization. [5]
Ionthermie was invented by French biochemist Olivier Fouche in 1978, [6] [2] although a separate source claims it was invented in 1979. [5]
While it has been described as pseudoscientific, [2] one study in 2006 reported modest results. [1] [7] : 120
