Niacinamide Complex Serum: Advanced Brightening & Barrier Repair

No. Skin purging only occurs with ingredients that speed up cell turnover, such as Retinoids, AHAs, or BHAs.

Niacinamide does not increase cell turnover, so it cannot cause a purge. If you experience new breakouts after starting a Niacinamide serum, it is likely an irritation reaction to a high concentration or a sensitivity to another ingredient in the complex, rather than a "detox" process.

ou cannot physically change the biological size of your pores, but Niacinamide can make them appear significantly smaller.

Pores look larger when they are stretched out by excess oil and dead skin. Niacinamide regulates sebum production so the pores don't get "clogged" and distended. Additionally, by supporting the skin's collagen framework, Niacinamide keeps the skin around the pore firm; when the skin is tight, the pore looks like a pinprick rather than a wide oval.

Yes. The old myth that these two "cancel each other out" or create a skin-flushing reaction is based on outdated research using non-stabilized ingredients.

In modern formulations, these two are actually a powerhouse duo for brightening. Vitamin C works to inhibit the production of pigment, while Niacinamide prevents that pigment from being transferred to your skin cells. Using them together provides a multi-level approach to treating dark spots.

"Pilling"—those small white grains that form when you rub your skin, usually happens because of a conflict between the serum's thickeners and your moisturizer or SPF.

Niacinamide serums often use high-molecular-weight polymers (like Xanthan Gum) to create a silky texture. If you layer a silicone-heavy cream or oil over the serum before it is fully absorbed, those polymers "crash" out of the solution. To prevent this, apply the serum to damp skin and allow it to dry completely for 60 seconds before layering.

You can—and should—use it for both. Niacinamide is not photosensitive, meaning it doesn't break down in sunlight or make your skin more prone to sunburn (unlike Retinol or AHAs).

In the morning: It acts as an antioxidant to shield skin from environmental pollutants and controls midday oiliness.

At night: It works to repair the skin barrier and soothe any inflammation accumulated during the day.

Because it is so stable, it plays well with almost every other active ingredient in your PM routine, including Retinoids and Peptides.
