Skincare, simply explained
Uneven tone, a shiny T-zone, or skin that needs a little more comfort? Niacinamide is a versatile daily ingredient that helps skin look more balanced and feel better hydrated.
Helps soften the look of dark spots and blotchiness, giving skin a more even appearance over time.
Helps skin hold onto moisture by supporting the protective outer layer that keeps it feeling comfortable.
Can help reduce excess surface oil, making it a useful option for a shiny forehead, nose or chin.
With regular use, niacinamide can improve the look of fine lines and uneven texture.
Niacinamide is a water-soluble form of vitamin B3, also called nicotinamide. It dissolves into the water-based part of a skincare formula, making it easy to include in light serums as well as richer moisturizers. It can be the main ingredient a product highlights or a useful addition to your everyday cream.
One of its useful roles is supporting the lipids in skin’s outer layer. These natural fats help keep moisture in, so the skin barrier can do its everyday job. Niacinamide also has a place in formulas for uneven tone and excess surface oil, which is why one product can suit several skincare goals.

Also known as: Nicotinamide, vitamin B3
Choose a serum or moisturizer that fits your routine. You do not need several niacinamide products at once.
Apply a serum after cleansing and before moisturizer. A niacinamide cream can be your moisturizing step.
Use it in the morning or evening as directed. Start less often if your skin is sensitive.
Finish your morning routine with broad-spectrum sunscreen, especially when caring for dark spots.
Niacinamide fits easily beside hydrating ingredients and other steps for a more even-looking complexion.
Adds light hydration to a routine focused on tone and comfort.
Moisturizing lipids that complement niacinamide’s barrier support.
Another option for a brighter, more even-looking complexion.
In a 12-week study, a moisturizer with 5% niacinamide improved the look of dark spots, fine lines, texture and red blotchiness compared with the same moisturizer without niacinamide.
Researchers found that niacinamide supports the natural lipids in skin’s outer layer. In dry skin, they also measured less water escaping through that layer.
Studies of a 2% niacinamide moisturizer measured reductions in skin oil. This helps explain its place in routines for a shiny T-zone.
A 2% to 5% product is a sensible starting point: these amounts have been studied for oiliness, tone and texture. You do not need the highest percentage on the shelf to get started.
Yes, if the product is designed for daily use and feels comfortable. Morning, evening or both can work; follow the label and build a routine you can keep up.
Yes, they can share a routine. Apply lighter products before thicker ones, and introduce them one at a time if they are both new to you.
Controlled studies support niacinamide for tone, texture and surface oil. Much of the direct facial research used 2% to 5% leave-on formulas.
The studies below explain what was tested and for how long. They describe particular formulas rather than a guaranteed result from every niacinamide product.

Cell research and observations in dry skin support niacinamide’s role in skin lipids and reduced moisture loss. This was not a large facial-product trial.

Two studies over four and six weeks found improvements in different measures of skin oil. The results varied between the groups.
Yes. A niacinamide moisturizer can be a comfortable companion to retinol. Keep following your retinol’s directions and start slowly with that step.
It can help reduce surface shine and improve the surrounding skin’s texture, which may make pores less noticeable. Pores do not permanently shrink or disappear.
Give it several weeks of regular use. Oiliness studies measured changes over four to six weeks, while a study of tone and fine lines followed people for 12 weeks.
