E in C Advanced

E in C Advanced

E in C Advanced is the latest antioxidant innovation clinically tested to provide the most superior protection against free radicals caused by environmental aggressors.

This powerful combination of 20% vitamin C (ascorbic acid) and 5% vitamin E (alpha-tocopherol) visibly corrects and protects against fine lines, wrinkles, dark spots, and rough skin while creating a thin barrier on the skin for extended protection.

Vitamin C focuses on the aqueous (or water-based) aspect of the skin, while vitamin E addresses the lipid (or fat-based) phase neutralizing harmful free radicals to ensure comprehensive protection for your skin.

  • When I tell you that you literally feel like your skin has a protective layer on it without feeling greasy, I'm not kidding. The texture is so smooth and absorbed quickly into my skin. I'm not sure if it's because I have combination skin, but I can literally see and feel my dead skin being rubbed off as I'm applying the serum onto my face which is amazing.

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

    What’s the difference between E in C Advanced and E in C Lite?

    E in C Advanced has a higher strength (20% Vitamin C + 5% Vitamin E) for maximum firming, brightening, and antioxidant protection. E in C Lite is gentler, perfect for sensitive skin or beginners.

    Can I use it every day?

    Yes! Use 3–4 drops every morning on clean skin, before moisturizer and SPF. New to Vitamin C? Start every other day to let your skin adjust.

    Is it good for sensitive skin?

    It’s safe for most skin types, but if your skin is highly sensitive, start with E in C Lite. Always patch test before full use.

    Why no ferulic acid like other Vitamin C serums?

    Ferulic acid is often used as a shortcut to stabilize Vitamin C, but at higher concentrations it can act as a pro-oxidant and speed up oxidation. Dr. Omar’s proprietary method keeps L-ascorbic acid stable at the ideal pH (3.5) for absorption, maintaining efficacy without ferulic acid.

    Can I use it with retinol?

    Yes! Apply E in C Advanced in the morning, retinol at night. This gives your skin 24-hour protection and renewal while minimizing irritation.
