For me, this combination product has shown more dramatic improvements in my skin than other products I have used in the past. I have been using it consistently for 6weeks with sunscreen and my skin has responded well to it. I have olive skin but with some redness and textured issues at baseline, but have noticed brightness and improved texture with consistent use. My friends and family have also seen the positive changes!

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

Who is Selenium in C Serum best suited for?

It's recommended for normal, combination, and mature skin types, especially for those concerned with advanced signs of aging, such as deeper wrinkles, uneven pigmentation and rough texture.

Can I use Selenium in C Serum with retinol or other strong actives?

Yes, but proceed with caution. Selenium in C already contains retinol in its formula, so additional retinol products should be introduced carefully to avoid irritation. Avoid pairing with strong exfoliating acids on the same day unless directed by a professional.

How soon can I expect to see results?

Most users report visible improvements in skin texture, tone, and radiance within 2 weeks of consistent daily use. Deeper signs of aging and pigmentation may take 8–12 weeks for more noticeable results.

What role does Selenium play in the formula?

Selenium acts as a potent antioxidant that works synergistically with Vitamin C to neutralize free radicals and reduce oxidative stress. Its inclusion is based on research supported by NCI Grant #1-R43-CA94484-0, making it one of the few antioxidant serums with documented scientific backing for diminishing the appearance of photo-damage.

How does Selenium improve stability and efficacy of Vitamin C?

Vitamin C is prone to oxidation, which can reduce its potency. Selenium helps stabilize Vitamin C by regenerating its antioxidant capacity, allowing it to remain active longer in the skin. This is why Selenium in C maintains its performance more consistently compared to single-antioxidant serums.

Excellent!

Love this product. Great investment for my skin care routine. For me, this combination product has shown more dramatic improvements in my skin than other products I have used in the past. I have been using it consistently for 6weeks with sunscreen and my skin has responded well to it. I have olive skin but with some redness and textured issues at baseline, but have noticed brightness and improved texture with consistent use. My friends and family have also seen the positive changes!

Holy grail!

Literally the almighty cup of radiance. A few drops of the beautiful crimson youth serum in the morning is all thats needed. I have been using for about 6 or 7 years and could not imagine my skin without it. HG status for sure!!

Adding Selenium in C and Velvet Gel

Having almost finished using my first bottle of Selenium in C along with Velvet Gel, I intend to keep them both in my skincare regimen. Using great products in tandem with these two wonderful ones, I see a clarity and radiance enhanced. I am so glad I took the advice of Amira on adopting these great serums - thank you Amira!!

Loving but Losing

New to my skincare routine. Just got about a week ago and have been loving this product! My skin is very happy and vibrant! Unfortunately, it slipped from my fingertips this morning and lost more than half down the sink, literal tears!!!

Best serum I have ever had

For all the different serums that I have used over the years, Selenium from Phyto-C is the best among all other brands or product lines I have tried. It works magic on my skin in just a few days. Not only does the serum get absorbed instantly without feeling sticky, it leaves my skin feeling soft and silky smooth. It also brightens my complexion and clears the problem area near my chin in just a week. I love how Selenium has a high concentration of Vitamin C, as well as Retinol. So that my skin can benefit from an improved complexion, while blemishes got cleared up. Last but not least, I love the VIP Rewards System with Phyto-C. It's simple and easy to use. And the best part is, it gives you direct saving to your purchase. Unlike other brands that offer different items or combination of items on promotion or for holiday season, I don't need to figure out which deal is the best; I simply use my VIP points and save money! What gets better than this?
