Ingredient Spotlight: Niacinamide

Niacinamide (nahy-uh-sin-uh-mahyd) may seem confusing to say, but the skincare benefits of this vitamin B derivative are crystal clear. It’s no wonder this potent powerhouse is added to everything from serums to sunscreen — read on to learn why.

What is niacinamide?

Niacinamide is the biologically active form of vitamin B3 — which is also called niacin or nicotinic acid. It’s the safest, most universally-suitable form of vitamin B3 that’s used in skincare. 

And though its name may sound synthetic, niacinamide is actually a water-soluble vitamin that’s naturally found in food. Because the ingredient works best when it’s applied in a leave-on product, it’s typically found in serums and moisturizers, rather than cleansers or scrubs.

What makes niacinamide such a powerful ingredient?

Niacinamide is a multi-tasking antioxidant. This B vitamin excels at several key skincare functions:

Strengthens your skin barrier

  • Works on a cellular level to repair and strengthen our skin barrier by increasing the number of ceramides in the skin, which means skin loses less moisture
  • Preventing skin from drying out keeps your complexion healthier, minimizing everything from fine lines to maskne

Helps relieve redness and inflammation

  • Reduces the production of inflammatory chemicals naturally released within the skin
  • Calms irritated skin and reduces redness associated with acne, eczema and rosacea

Fights acne

  • Reduces skin’s sebum production levels
  • Ideal for those with acne or acne-prone skin
  • Helps minimize pore size
  • Reduces redness and inflammation

Combats the signs of aging

  • Diminishes fine lines and wrinkles by firming skin and improving elasticity
  • Strengthens skin’s barrier function to prevent UV and environmental damage
  • Reduces hyperpigmentation (aka sunspots)
  • Reduces redness and inflammation

Who benefits from having niacinamide in their skincare regimen?

Everyone! Niacinamide is suitable for, and will benefit, all ages and skin types. It can be used morning or night, is calming to the skin, and is stable to heat and light. Niacinamide is also completely safe for use during pregnancy and breastfeeding. If you have sensitive skin, niacinamide can be a great first step before progressing onto retinoids, as it helps increase your skin’s tolerance to them.

Can you combine niacinamide with vitamin C?

There’s a popular myth that you can’t use niacinamide in conjunction with vitamin C, as they cancel each other out — but this notion has been scientifically disproven. The false belief is based on an outdated study involving un-stabilized forms of the two vitamins, as well as unrealistic pH and heat levels. Niacinamide can, in fact, work well with vitamin C — and thanks to the wonders of modern cosmetic chemistry, the two ingredient superstars are now routinely combined effectively.

Dr. Lee’s Last Word

Niacinamide is truly one of those wonder ingredients that is so versatile and beneficial for addressing a variety of concerns. It’s moisturizing, but it also helps control sebum production, so we can use it on acne-prone skin and aging skin, too. It’s anti-inflammatory, so it works for patients with sensitive skin and those with conditions like eczema or rosacea. And because it bolsters your skin’s barrier function, it guards against all kinds of environmental damage.
