The Ultimate Guide to The Ordinary Niacinamide: Benefits, Usage, and Reviews

Niacinamide, also known as Vitamin B3, is a water-soluble vitamin that has been gaining popularity in the skincare industry. While it’s not a new ingredient, it’s recently been dubbed the “ordinary niacinamide” due to its prevalence in the popular skincare brand, The Ordinary. In this article, we’ll explore the benefits and downsides of niacinamide, why it’s become so popular, and how to incorporate it into your skincare routine.

What is Niacinamide?

Niacinamide is a form of vitamin B3 that has been shown to have numerous benefits for the skin. It’s a water-soluble vitamin, which means it dissolves in water and is easily absorbed by the body.

Benefits of Niacinamide

One of the main benefits of niacinamide is that it helps to improve the skin barrier. The skin barrier is made up of lipids that help to lock in moisture and protect the skin from external factors. Niacinamide helps to improve the barrier function by stimulating the production of ceramides and other lipids.

Another benefit of niacinamide is that it can help to reduce inflammation in the skin. Inflammation can lead to redness, irritation, and even acne, so reducing inflammation can help to improve the overall health and appearance of the skin.

Niacinamide has also been shown to reduce the appearance of fine lines and wrinkles. It does this by stimulating collagen production and improving the overall texture of the skin.

Downsides of Niacinamide

While niacinamide is generally considered safe, some people may experience side effects. These can include redness, itching, and dryness. If you’re experiencing any of these side effects, it’s important to stop using the product and speak with a dermatologist.

How to Incorporate Niacinamide into Your Skincare Routine

Niacinamide can be found in a variety of skincare products, including serums, moisturizers, and toners. When incorporating niacinamide into your skincare routine, it’s important to start slowly and patch test first to ensure you don’t have any adverse reactions.

Some popular niacinamide products include The Ordinary Niacinamide 10% + Zinc 1% serum and the Cosrx Galactomyces 95 Tone Balancing Essence. Both of these products contain niacinamide and are highly regarded in the skincare community.


Overall, niacinamide is a beneficial ingredient that can improve the health and appearance of the skin. It’s important to patch test any new products and start slowly when incorporating niacinamide into your skincare routine. With regular use, niacinamide can help to improve the skin barrier, reduce inflammation, and even reduce the appearance of fine lines and wrinkles.
