About i-On by Dr. Xi i-On by Dr. Xi is a New York–based science-driven skincare and wellness brand founded by Dr. Xi Huang, a former NYU Medical School faculty member with decades of research experience in iron metabolism and oxidative stress. The brand’s patented De-Ironizing Inducer (DII®) technology is designed to help address excess iron in the skin – an underrecognized contributor to visible aging and uneven tone. By focusing on underlying oxidative triggers rather than surface symptoms alone, i-On introduces a proactive approach to healthier-looking skin and visible skin longevity.
