Our 2026 Buyer’s Guide to Niacinamide (Serum, Cream + More)

January 09, 2026

Niacinamide is a powerful form of vitamin B3 known for its ability to reduce inflammation, improve skin elasticity, protect against oxidative stress, and more. This ingredient is a great addition to any skincare routine, due to its many benefits and versatility across skin types.

We feature niacinamide in many of our product formulations at Isomers Skincare to address several skin concerns. Whether you want to tackle visible signs of aging, uneven skintone, or UV damage, keep reading for our full niacinamide buyer's guide! 

For Anti-Aging

Looking to get a jump on your anti-aging skincare? Our 0.1% Retinol 1% Azelaic Acid 3% Niacinamide is a great serum for the Correct step of your skincare routine (you can learn more about the four skincare phases in our Product Philosophy).

This low-dose retinol-based serum helps promote skin cell turnover, reduces the appearance of fine lines, and boosts skin elasticity. 

The niacinamide in this serum helps improve your skin texture by strengthening the skin barrier, enhancing moisture retention, and protecting against environmental stressors.

For Your Nighttime Routine

Everyone needs a good nighttime serum! Niacinamide pairs well with retinoids to boost the skin’s natural nocturnal repair process. Our Retiniacin Night Renewing Treatment Serum combines these two powerful ingredients to reduce the appearance of large pores, strengthen the skin barrier, boost collagen production, and minimize the appearance of fine lines and wrinkles.

For Post Sun-Skincare

While we all love the sun, it can do a number on our skin if we don’t take steps to protect it! In addition to wearing SPF (which you should do all year long, even in winter), you can provide added protection to your skin by pairing vitamin C and niacinamide together. 

Our Vitamin C After Sun Body Cream and Brightening Cream are rich in antioxidants and formulated to target visible signs of photoaging and sun damage, enhance skin radiance, and shield against environmental stressors.
