Hyabest (S) LF-P An Ideal Hyaluronic Acid for Skin-beauty Supplements Since 1983, the Kewpie Corporation of Japan has been producing a wide range of Hyaluronic Acid products, along with its sodium salt. Through these efforts it has become one of the world s leading producers, based on the products high degree of refinement and scientifically proven quality. Food grade Hyabest (S) LF-P, developed specially for products that satisfy the beauty from within concept, has become one of Kewpie s most popular brands. Kewpie recently obtained new data showing that, taken orally, Hyabest (S) LF-P suppresses skin damage due to ultraviolet radiation. In June, Kewpie released this data to the 2013 International Society for Hyaluronan Sciences conference, held in Oklahoma City. The data, involving hairless mice, shows that daily oral administration of an equivalent of 200 mg of hyaluronic acid for six weeks significantly suppressed the decrease of skin moisture volume and resultant wrinkle formation associated with ultraviolet radiation (Hyabest (S) LF-P vs. UV irradiation contagion on skin). The publication of this data follows on Kewpie s previously conducted testing, which showed a significant increase in skin moisture, along with other improvements, as a result of six weeks of daily oral intake of 120 mg of hyaluronic acid (Hyabest (S) LF-P skin improvement effect), (Journal of New Remedies & Clinics Vol.58 No.8; Aug.10, 2009). Health food holds about a USD $6.85 billion share of the Japanese market. Sixteen percent of this market, about USD $1.12 billion, comprises beauty-related foods, of which 24%, equal to about USD $269 million, contain hyaluronic acid. 1 With the popularity of Kewpie s marketing programs, solidly supported by carefully researched scientific evidence, foods and beauty supplements containing the company s hyaluronic acid are currently enjoying unprecedented popularity in Japan. 1.
