Short answer: niacinamide is a form of vitamin B3 that helps support your skin barrier and can help the skin look more even, with less visible pores and less shine. It is gentle, and it plays well with almost everything.

If retinol is the star that needs careful handling, niacinamide is the friendly helper that gets along with everyone.

What does niacinamide do?

• Supports your skin barrier, so skin holds on to moisture better.
• Helps the look of uneven tone, such as dullness or dark marks.
• Helps the look of pores and oiliness.
• Calms the look of redness for many people.

Who is it for?

Almost everyone: dry, oily or combination skin, in your 30s, 40s, 50s and beyond. It is especially nice if you want a simple ingredient that is not harsh.

How to use it

1. Look at the ingredient list. You may already have it. Many moisturizers and serums include niacinamide.
2. Use it morning, night, or both. It works at any time of day.
3. Layer it under your moisturizer if it is a serum, or just use a moisturizer that contains it.
4. Be patient. You may notice more even-looking skin after 4 to 8 weeks.

Can I mix it with retinol and other ingredients?

Yes, in most cases. Niacinamide pairs well with retinol, hyaluronic acid and peptides, and it can make a retinol routine feel more comfortable. If your skin tingles, use it on its own for a week and add the others back slowly.

Common mistakes

• Thinking more is better. Very high percentages can cause flushing or irritation for some people. A moderate amount works well.
• Expecting overnight results. It is a slow, steady helper.
• Skipping a patch test if your skin is very sensitive.

Where you can find it

Niacinamide is in many everyday products. For example, Olay Regenerist Micro-Sculpting Cream on Amazon lists niacinamide along with peptides and hyaluronic acid, and CeraVe Skin Renewing Retinol Serum on Amazon combines it with encapsulated retinol and ceramides. Compare the two in Olay vs CeraVe, or see our 3 drugstore anti-aging picks.
