What is niacinamide?

If you’re skincare fanatics like us, you may have heard the ingredient Niacinamide pop up here and there a few times. Vitamin B3 also known as niacinamide is an ingredient made for skin brightening benefits. Our body does not produce the vitamin on its own so therefore we have inserted it into various skincare products and supplements.

The Benefits of Vitamin B3

The key benefits of Vitamin B3 are: it reduces the appearance of dark spots and discoloration, leaves the complexion looking even and bright, and increases skin hydration and moisture. Dennis Gross, MD, New York dermatologist and founder of Dr. Dennis Gross Skincare, explains that “‘niacinamide improves ceramide synthesis, which strengthens the barrier function [of the skin] and prevents transepidermal water loss.’”

Not only is it anti-inflammatory, but it promotes the building of the skin’s barrier, the evening of skin tone, and the brightening of skin. Niacinamide, which is the active form of vitamin B3, has us all in awe of its extensive benefits that has been clinically proven to decrease pore sizes and reduce the appearance of dark spots.

A proven anti-inflammatory, niacinamide is also an effective treatment for rosacea, acne, and hyperpigmentation. According to research conducted by Dr. Hanley and Dr. Jiang, both from the Department of Dermatology at the University of San Francisco, niacinamide “reduces melanosome transfer from melanocytes to surrounding keratinocytes. One study showed that 5% niacinamide moisturizer provided 35–68 percent inhibition of melanosome transfer from melanocytes to keratinocytes.”

Vitamin B3’s Skincare Power Duo

Another fact that you should know about skincare products is that they work almost ten times better when paired with certain ingredients, forming a “power duo.” “When coupled with acetyl glycosamine (NAG), it’s brightening power increases dramatically.” says LeCerre Skincare Founder Cathy Beaupain. In regards to brightening and evening skin tone, niacinamide “‘works in a way that is complementary to commonly used tyrosinase inhibitors [the enzyme that controls the production of melanin]”, such as hyaluronic acid and retinol, “to deliver on a multi-mechanistic, pigment-evening benefit,’” says skincare researcher Barbara Green.

How To Use It

After washing your face, directly apply 1-2 pumps of the serum on your hands. Then rub this serum directly onto your face and neck. Apply to the entire face and neck for most effective skin brightening. Do this process once in the morning and once in the evening. Follow with whatever moisturizers or serums you prefer.
