Martha Stewart and dermatologist Dhaval Bhanusali, MD teamed up years ago to create ELM Biosciences, and “the hero serum—A3O Elemental—was the foundation,” our editor reports. “A first-of-its-kind antioxidant serum, it harnesses the power of ELM Bioscience’s patent-pending A3O Complex, which comprises acetyl zingerone, bakuchiol and a ferulic acid ester.” Dr. Bhanusali adds, “A3O really looks at the different components of antioxidant/anti-inflammatory/anti-aging complex.”
