I spent three decades giving facials to Hollywood A-List . I saw every ingredient, every technology, every trend and how it worked on my clients. Nothing compared to human stem cell-derived exosomes that I was using after microneedling. I wanted to create the most powerful anti-aging serum in the world. I worked with top stem scientists for 8 years. So I built a serum around them—billions per bottle, hand-cultured, delivered via Lipid-Lock™ nanotechnology. The serum sold out within an hour of launch at Violet Grey and has disrupted the luxury science-backed skincare industry. “This serum is a true innovation.” Oprah Daily. — Angela Caglia, Founder Patent-pending SignalSource™.
