In 1996, Royal Thai Medical customized the exclusive maintenance product FILTERS (translation: filter mystery) to the senior members of the institution. When the members spent more than 3 million baht (about RMB 570,000) in the institution, they could make an appointment to order a set of FILTERS maintenance kit. The reserved price of the kit was 100,000 baht (about RMB 19,100), which was a sky-high skin care product among the skin care products of that year, not only the price was close to 20,000 yuan. Moreover, it is not only expensive, but also stipulated by Royal Thai Medical that the skin care suit should only be sold to senior members, and its sales volume is very small, and it has never appeared in the market, only circulating in the star circle. Female stars in Thailand are crazy about it. In order to obtain the qualification for purchasing the high-priced skin care products, they spend wildly in royal medical institutions, and some female stars are even willing to speak for the royal medical institutions for free to obtain the qualification for purchasing a set of FILTERS maintenance kits.

　　So how did Thai FILTERS become a luxury among luxury goods? The main reason is that it is backed by Royal Thai Medical, and its authority and professionalism are recognized by Thai nationals. Because Royal Thai Medical once served members of the Royal Thai Family, everyone felt that using its products was a status symbol. Another main reason is that the main components of the ILTERS (filter mystery) care kit are Bosone (chemical name: hydroxypropyl tetrahydropyranol) and nicotinamide (chemical name: β-nicotinamide mononucleotide), which have remarkable anti-aging effects. Anti-aging has always been a compulsory course for female stars. In order to keep a glamorous appearance in front of the screen, anti-aging has become the pursuit of female stars to keep their skin young.

　　A so-called black bandage lady cream, which is also very popular recently, is also popular because of its anti-aging component Bose. The originator of boson is the filter mystery, and its content far exceeds the black bandage lady cream on the market at present. Of course, the price of black bandage compared with the filter mystery is still quite close to the people. No wonder the filter mystery can become a luxury among luxury goods, and it is hard to sell a box at a high price, which makes actresses crazy.
