They are all liars. You should watch more TV stations. Their advertisements are the same as Schniemi's black hair in Taiwan Province Province and black floating seaweed mousse in South Korea. It is said to be melanin, and brown algae is extracted from the ocean. Even the advertising model and advertising words are the same. They all invite some old TV actors who have long been unpopular, plus some old audiences. The only difference is the different actors. Some so-called experts come from South Korea and some from Taiwan Province Province. And without a physical store, an item that comes to a physical store and official website doesn't have can't be true.
