Skin-First Formulas

Backed By Science, Not Hype

When I first stabilized vitamin C in liquid form in 1995, the world believed it was impossible. That breakthrough not only transformed skincare, it became the foundation on which Phyto-C was built — a company that grew from my small lab in New Jersey to serving more than 35 countries worldwide.

From the beginning, my mission has been clear: to create formulas rooted in science, powered by nature, and uncompromising in their integrity. Each product is backed by decades of clinical research, crafted with medical-grade ingredients, and made in fresh micro-batches to ensure purity and potency.

Today, my son, Dr. Eddie Omar, carries this legacy forward. He leads Phyto-C with the same values I began with — an unwavering dedication to science, innovation, and results that endure.
