FAQ
FAQ
What kind of brand is AYURMASTER?
AYURMASTER is a brand of reverse aging care products developed by a startup from Yokohama City University's Longevity Science Laboratory, which has studied the mechanisms of cellular aging and rejuvenation for many years. It combines advanced life science with Ayurvedic beauty and health theory, based on the laboratory's research. The brand is operated by ICHIBAN LIFE CORPORATION.
Are the ingredients from Japan?
Our herbs come from Bangladesh, but quality testing, quality control and manufacturing are carried out in Japan. Bangladesh lies in the delta of the Indian subcontinent; its rivers carrying nutrients and minerals from the Himalayas, fertile soil and warm climate make it ideal for growing herbs.
Why are your products priced higher?
Our products are formulated based on many years of basic research on rejuvenation. Every herb we use is tested, and only those that meet our standards are used. Products are made in state-of-the-art facilities, and every unit is inspected.
Do your products contain preservatives?
To maintain quality, our cosmetics contain a minimal amount of preservative. We also ran cytotoxicity tests* on preservatives and use the least toxic one at the lowest concentration. Our health foods contain no preservatives. *Company research (provided by Yokohama City University)
Why doesn't Scalp Cleansing (shampoo) lather?
We found that surfactants that lather well are highly irritating to scalp cells (cytotoxicity*) and burden the scalp, so AYURMASTER Scalp Cleansing uses a mild, non-lathering surfactant. It cleanses gently while protecting the scalp's barrier function. Please try the gentle feel of non-lathering Scalp Cleansing for yourself. *Company research, based on cytotoxicity test results (provided by Yokohama City University)
