The “saunality skincare for sauna and bath“ series is a skincare line designed for sauna use that can also be used in daily routines. This series is an evolution of the “saunality” line, which won the “OMOTENASHI Selection 2023-2024,” and includes a full lineup of products such as lotion, emulsion, cream, and hair growth tonic. Soltelas Co., Ltd., established in 2020 and engaged in skincare products and fitness business, leverages the specialized knowledge of CEO Munemasa, who has expertise in pharmacology and biochemistry, and COO Matsuura, who is well-versed in physiology and kinesiology, to develop products. Overcoming the risk of bankruptcy after its founding, the company launched the “saunality” brand of cosmetics in 2023, under the vision of “creating a bright and happy future.” The brand now holds approximately 65% of the domestic sauna skincare market. During the bankruptcy crisis, founders Munemasa and Matsuura returned to their roots and began developing skincare products that utilized their expertise. They discovered that most lotions sold in bathhouses were composed mainly of water, with analysis revealing that 99.8% of the content was water. Additionally, they found it contradictory that typical creams would clog pores. This led them to develop products aimed at providing “truly desired, honest solutions” for customers. The products are specialized for clean skin, achieving an optimal formulation that does not hinder the absorption of ingredients. The ingredients penetrate deeply into the stratum corneum and include Japanese medicinal herbs and traditional Japanese plants. Manufacturing takes place in the ISO-22716 certified factory located in the nature-rich city of Karatsu, Saga Prefecture, where 10 craftsmen hand-produce only 300 units per production. The packaging and containers are entirely designed in-house to express the beauty of Japan, incorporating elements such as “wood-grain lids,” “gold leaf patterns,” and “kimono obi” to convey a sense of quality. Customers can choose from the lineup according to the specific skincare functions they desire, depending on their skin concerns. The numbers indicate the order of use, starting with “00.” The letters following the numbers represent the series: “t” for total care, “a” for anti-aging care, “p” for a premium skincare experience, and “h” for sensitive or severely dry skin. All products in the “saunality” series are quasi-drugs approved by the Ministry of Health, Labour and Welfare for their efficacy and effectiveness.
