Niacinamide & Vitamin C: Better Together?

Niacinamide has become the skin care ingredient dujour, with Vitamin C following close behind. Labeled the “it” ingredient by influencers, Niacinamide formulations have jumped more than 220% in recent years. Vitamin C has also experienced a resurgence, as evidenced by elevated sales and Google searches. In fact, both Niacinamide and Vitamin C consistently rank in the top five searched skin care ingredients on the Internet.

Admired for their complementary tone-evening and brightening powers, it might be assumed that using Niacinamide and Vitamin C together provides enhanced benefits. However, Niacinamide and Vitamin C are a controversial pair. Over time, some have claimed that combining the two ingredients can neutralize the effectiveness of each—or, worse yet, create a substance that reddens skin.

With sunspots and age spots ready to pop up under the summer sun, we were eager to learn more about these ingredients and how they might help (or hurt) our brightening routine. For answers, we turned to skin care guru Peter Thomas Roth. An influential segment leader in the beauty industry, Roth is known for creating clinically stronger formulas and leads all research and development at his state-of-the-art lab and manufacturing facility.

The newest innovation to emerge from Roth’s lab is Potent-C™ Niacinamide Discoloration Treatment. Here, Roth reveals the science behind this breakthrough formula and settles the Niacinamide and Vitamin C debate once and for all.

What do you think about pairing Niacinamide and Vitamin C?

Go for it! The idea that you can’t combine these ingredients is a myth. It doesn’t matter what order you apply them, it’s more about the product formulations. A general rule of thumb is to apply skin care in order of thin to thick, using the thinnest product first and the thickest product last. For example, if you have a Vitamin C serum and a Niacinamide cream, you would apply the Vitamin C serum first.

Why do you think some people believe you can’t mix these two ingredients?

There are outdated studies from the 1960s that combined unstable forms of Niacinamide and Vitamin C at extremely high temperatures. When you use stable forms of these ingredients, the results are actually quite impressive! I’m always looking to innovate and take things to the next level, which is why I took my cult-favorite Pro Strength Niacinamide Discoloration Treatment and added THD Ascorbate Vitamin C. Unlike the traditional Vitamin C that was used decades ago, THD Ascorbate Vitamin C is not only ultra-stable but also 50 times more powerful.

I’m all about helping my customers to achieve clinically stronger results! When my Pro Strength Niacinamide Discoloration Treatment first launched, it was a viral sensation—everyone loved it and kept coming back for more. I packed the formula with a 15% Brightening Complex of Niacinamide, Tranexamic Acid, Kojic Acid, Alpha Arbutin and Pentapeptide, and the results were out of this world! My new Potent-C™ Niacinamide Discoloration Treatment has the same 15% Brightening Complex, plus THD Ascorbate Vitamin C for an even stronger brightening solution. Now, instead of using two products to get the combined results of Niacinamide and Vitamin C, you only need one!

How should people use your product in their skin care routine?

Apply this lightweight gel-cream twice daily, after your cleanser or serum. Follow with moisturizer. To see the best results, use consistently morning and night…and don’t forget to apply sunscreen during the day! Wearing a broad-spectrum sunscreen will help protect your brighter-looking skin and keep dark spots away. You’re going to look gorgeous!
