Études Cliniques


The Iyashi Dôme détox cure

“For centuries, the Japanese buried themselves in the sand of certain hot springs to purify themselves and eliminate their toxins. The heat (the long infrared rays emitted by the sun) heated the sand and gave it precious properties for the body. This tradition is perpetuated today by the Iyashi Dome with the long infrared.”

The study of the detox benefits of the Iyashi Dome

A clinical trial was carried out in Switzerland on 22 patients. Samples of sweat were taken from each patient’s body after a session of Iyashi Dome lasting 25 minutes. The sweat was taken using a Pasteur pipette from the patient’s chest and arms. No metal utensil was used when taking sweat samples. The Laboratory MGD in Geneva (Switzerland) analyzed the sweat and then compared the samples with the analysis of urine samples from the same patients. “Analysis of the chart in figure 2 shows that the Iyashi Dome increases the amount of toxic heavy metals eliminated such as Strontium, Barium, Nickel, Lead, Molybdenum, Tellurium, Chromium, Cobalt, Arsenic, Cadmium, Aluminium and Copper. This chart shows that the quantities of heavy metals are higher than the average quantity of 514μg/l, with particular effectiveness with regards to the elimination of Aluminium. […]

« Analysis of 2 ml of sweat taken from patients who underwent Iyashi Dôme Far Infrared sessions lasting 25 minutes demonstrates that there is a real impact on the elimination of heavy metals from the body. Simultaneous analyses of urine samples show the heavy metals are essentially eliminated through sweat.
The action is particularly efficient with regards to the elimination of Aluminium».

Iyashi Dome Anti-Aging Cure

“Facial skin ageing is an inescapable natural process that results in the appearance of wrinkles and fine lines, pigmentation spots, loss of skin firmness and elasticity and a reduction in the radiance of the complexion. Ageing factors can be intrinsic (genetic, hormonal, …) and extrinsic (stress, climatic aggressions, pollution, tobacco …). Apart from cosmetics, there are nowadays other non-invasive methods to fight against the effects of time on the skin.”

The study

[…] The study was carried out on 13 patients, from 31 to 63 years-old, with skin phototype between II and IV according to the Fitzpatrick Classification Scale. The 8 Iyashi Dome sessions each lasted for 30 minutes and were carried out twice a week over four weeks.

In order to take the research further, biometric measurements were carried out on both the face and body, using the Cutometer® to measure skin elasticity […], the Corneometer® to measure skin hydration and the Mexameter® to verify the level of haemoglobin and melanin concentrations in the skin […]. Finally, the Iyashi Dome’s actions on dermis thickness of the face and body were visualized and measured using High Frequency Doppler Echography. These measurements establish the increase or decrease in thickness of the dermis and, therefore, of the collagen and elastin fibres that compose the skin’s connective tissue.

[…] The far infrared rays emitted by the Iyashi Dome® are effective in improving the skin’s quality and physiological properties […]. More specifically, after 4 weeks’ use the product improves skin density with an increase in the thickness of the dermis of both face and body, improves facial skin radiance, decreases facial skin roughness, decreases facial wrinkle volume, improves skin hydration in the face and body, improves the complexion (evenness and luminosity of facial skin), improves skin elasticity and firmness of the body and face, stimulates skin microcirculation and reduces the signs of skin ageing. The product was judged to be effective on all skin phototypes and considered as being pleasant to use.
