Robkellermd

Robkellermd.com sells physician-formulated nutraceuticals and topicals for skin, hair, gut and immune health. Flagship lines include the “Okana” antioxidant skin-care regimen ($110–$180), “Kellerman” probiotic and polyphenol supplements ($39–$79), and the “Elevai” prestige stem-cell hair serum ($220). All sales are direct-to-consumer through the site; no third-party retail or Amazon storefronts. The brand’s hook is that every formula is invented, patented and clinically piloted by board-certified dermatologist Dr. Rob Keller, who also offers virtual consults bundled with product plans. Products feature high-dose antioxidants (glutathione precursors, resveratrol, NAD+ boosters) and micro-encapsulated delivery systems that are promoted as “prescription-grade without a prescription.” Limited-run micro-batches and amber glass packaging reinforce a medical-lab positioning. Core buyers are 30-55-year-old professionals in North America who want dermatologist-level results but prefer supplement routines over in-office procedures. They value science-backed ingredient lists, third-party purity certificates, and the ability to message the doctor directly through the patient portal. Robkellermd competes in the premium “doctor-founded” beauty-from-within space against celebrity dermatology brands and high-end nutricosmetic labels. It differentiates by keeping the physician inventor visibly central to R&D and customer support, publishing small-scale clinical data on its own site, and refusing retail mark-ups, allowing prices to sit 20-30 % below comparable prestige cosmeceutical lines.
