Initially popular, Debon Isa Knox was based out of Taiwan. They were originally started by Sunpower Nutraceutical Inc, and they were known for anti wrinkle creams, moisturizers, emulsions, and potent serums. However, Debon Isa Knox’s popularity was short lived. Unfortunately, their line apparently did not have enough of the right components, and customers stopped buying it. They have currently gone out of business and the line has been discontinued, whether because of bad marketing or faulty products. But being that it was created by a company that had years of previous experience, we are leaning toward the second.
