Ingredients & Branding

Is Niacinamide The Ordinary?

The Ordinary has become so synonymous with niacinamide that some people assume it's the same thing. It's not. Niacinamide is the ingredient; The Ordinary is just one of many brands that make it famous.

If you've spent any time on skincare forums, you've seen it: "I bought The Ordinary Niacinamide" or "Should I try the niacinamide from The Ordinary?"

Some people talk about the ingredient and the brand like they're the same thing.

So is niacinamide The Ordinary - or is the relationship more complicated?

Niacinamide is like flour; The Ordinary is one bakery that makes bread with it. Many bakeries use flour. The Ordinary just happens to make a very famous loaf.

Quick answerNo, niacinamide is not The Ordinary.

Short version

Story in brief

The Ordinary, launched in 2016, disrupted the skincare industry by offering effective ingredients at remarkably low prices. Their Niacinamide 10% + Zinc 1% serum quickly became one of their bestselling products, making the ingredient more accessible to a wider audience.

This success led to niacinamide becoming strongly associated with The Ordinary in many people's minds. However, niacinamide is a standard ingredient in skincare, used by almost every brand in some capacity, from CeraVe and Cetaphil to Paula's Choice and La Roche-Posay.

The Ordinary's version stands out for its high concentration and minimal formulation. But the ingredient itself is widely available across the skincare market.

Evidence

What the evidence shows

Definition

What is niacinamide?

Niacinamide is a form of vitamin B3 that's widely used in skincare. It's a multi-functional ingredient that supports the skin barrier, regulates oil production, reduces inflammation, and helps with hyperpigmentation. It's one of the most researched and trusted skincare ingredients available.

  • Found in hundreds of skincare products from dozens of brands
  • Works at concentrations from 2% to 10% and higher
  • Suitable for most skin types
  • Known for its versatility and compatibility with other ingredients

Explanation

What is The Ordinary's niacinamide product?

The Ordinary's Niacinamide 10% + Zinc 1% is a serum that combines vitamin B3 with zinc PCA. The 10% concentration is relatively high compared to many other products, and the zinc adds oil-regulating benefits. The product is water-based, minimal, and affordable. It's become iconic not because it's the only niacinamide product, but because it makes a high concentration accessible at a low price.

Benefits

Why The Ordinary's version is so popular

The Ordinary's niacinamide serum gained a cult following for several reasons:

  • 10% concentration is higher than most products on the market
  • Very affordable price point (typically under $10)
  • Minimal formulation with no unnecessary fillers
  • Highly effective for oil control and pore appearance
  • Transparent about ingredient percentages and formulation
