Is Niacinamide Just A Trend? | As Seen in Bazaar

You may have noticed over the past few years, a growing buzz around the ingredient known as, niacinamide. Walk down the aisle of any beauty store, and you’re likely to see this ingredient being highlighted on a wide range of products. Are the benefits truly that effective, or is it just another trend formulators are reaching for? As seen in Bazaar, Dr. Mona Foad answers these questions on the truths behind niacinamide.

Why has this ingredient become so popular to formulate with?

Niacinamide has become popular because it checks a lot of boxes for both consumers and formulators. It is a very versatile ingredient that can help with redness, excess oil production, uneven skin tone, enlarged pores, and even skin barrier support. Niacinamide does have broad benefits and is generally well tolerated by most skin types. This makes it easy to incorporate into a wide range of products.

Are the benefits of niacinamide effective?

Niacinamide is a form of vitamin B3 that has been shown to help strengthen the skin barrier, reduce inflammation, improve hyperpigmentation, regulate oil production, and support overall skin health. Whether it’s effective in makeup products depends on the concentration and how long the product stays on the skin. A foundation or primer  may provide some added skincare benefit over time, but I wouldn’t rely on those products alone if you’re trying to treat a specific skin concern. Dedicated skincare products with a focus on niacinamide will usually deliver more meaningful results.

What are the benefits for skin vs. hair/scalp?

Niacinamide is best known for helping calm inflammation, improve discoloration, support the skin barrier, and balance oil production. On the scalp, it can help reduce irritation and support a healthier scalp environment by improving barrier function and moisture retention.

Does Niacinamide risk irritation?

Yes–although niacinamide is often marketed as a gentle ingredient, I have seen patients develop irritation from it. It’s not because it is inherently harsh, but usually because consumers are layering multiple products containing it, or choosing formulations with intense, high concentrations. As it has become more common, people may unknowingly be layering it several times throughout their routine. That can mistakenly increase the risk of redness, stinging, or irritation, especially in sensitive skin types.

Can sensitivity risk increase with overuse? 

It certainly can, as the challenge is that consumers often don’t realize how many products contain niacinamide today. Someone may have it in their serum, moisturizer, sunscreen, foundation, and even haircare products. While niacinamide is typically safe, cumulative exposure may increase the likelihood of irritation for some individuals.

Is Niacinamide just a trendy ingredient?

I don’t think it is a passing trend. It has a strong amount of research behind it and offers real benefits for many patients. However, not every product needs to contain it. More isn’t always better when it comes to skincare. I would rather see patients use a few well-formulated products consistently than feel pressured to chase a single ingredient in every step of their routine.
