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.

    Frequently Asked Questions

    Is Supreme Serum suitable for sensitive skin?

    Yes. Supreme Serum is formulated for all skin types, including sensitive skin. However, if you are new to high-potency formulas, we recommend starting with a patch test and introducing it gradually to allow your skin to adjust .

    Can I use Supreme Serum with other active products like retinol or exfoliants?

    Yes, but we recommend alternating active products to minimize potential irritation. Supreme Serum pairs well with hydrating products, antioxidant serums, and peptide treatments. If you use retinol, apply it at night and keep Supreme Serum in your morning routine.

    How long will it take to see results with Supreme Serum?

    Many users report a more radiant complexion within 2–4 weeks, with improvements in the appearance of dark spots and fine lines becoming more noticeable after 8–12 weeks of consistent use.

    Will Supreme Serum make my skin peel or tingle?

    Some mild tingling can occur initially due to the high concentration of Vitamin C and kojic acid. This is normal and typically subsides as your skin adjusts. If irritation persists, reduce frequency or layer with a calming gel or lotion.

    How is Supreme Serum different from Serum Fifteen or Twenty?

    Supreme Serum contains a broader mix of brightening and corrective ingredients, including kojic acid, arbutin, and amino acids, making it more targeted for uneven skin tone and visible imperfections, while Serum Fifteen/Twenty focus primarily on Vitamin C concentration.
