What if we told you there was a single skincare ingredient that could do everything from boost collagen production to smooth fine lines to fight acne, soothe inflammation, minimize redness, shrink pores, keep oil under control, tackle dark spots and repair sun damage? Well, there is, and it’s called niacinamide, aka vitamin B3. That’s why you’ll want to add a niacinamide serum to your skincare routine to reap all the benefits. Before you start slathering one on, read up on what Suneel Chilukuri, M.D., Cosmetic Dermatologist and Founder of Refresh Dermatology in Houston, Texas, has to say on exactly what niacinamide is, the best niacinamide serums, and the best way to apply them.
What is niacinamide and what are its skincare benefits?
“Niacinamide plays many roles in the body and is highly involved in healthy skin function,” Dr. Chilukuri says. “It is an antioxidant, it reduces transepidermal water loss (TEWL) and improves the skin’s barrier function. It helps to brighten skin and reduce inflammation in the skin. It can also help to increase collagen synthesis to strengthen skin. Furthermore, it inhibits glycation, which is a non-enzymatic reaction between sugars and proteins leading to the formation of advanced glycation end products, or AGE. Glycation is implicated in many age-related breakdowns and diseases, including yellowing of the skin and collagen breakdown. Topical supplementation with niacinamide is highly beneficial to healthy youthful-looking skin.”
Why is niacinamide extra potent in a serum?
“The base of a formulation does not change the ‘potency’ of an ingredient, but can increase the efficacy,” Dr. Chilukuri says. “Serums tend to penetrate more readily into the skin. My favorite niacinamide serum is the highly effective PCA SKIN Vitamin B3 Brightening Serum. That said, a well-formulated cream-based product can also effectively deliver niacinamide into the skin.”
What should you look for in a niacinamide serum?
“Niacinamide can be used at differing percentages,” Dr. Chilukuri says. “Between four and six percent is usually what I look for therapeutic treatment. If it is quite low it can still have benefits, but not as many as you will see from a therapeutic level. Cosmetic elegance is also important; if something doesn’t feel good on your skin, compliance with usage is lower so you will not see as dramatic results.”
How often do you have to apply niacinamide serums to see results?
“At least once daily is essential,” Dr. Chilukuri says. “For example, retinol products containing niacinamide are applied only at night. Serums like Vitamin PCA SKIN B3 Brightening Serum are applied in both your morning and evening regimens.”
What is the best way to apply them?
“Serums are best applied to freshly cleansed skin,” Dr. Chilukuri says. “In the morning it should be followed by sunscreen and in the evening followed by a nighttime moisturizer.”

1. PCA SKIN Vitamin B3 Brightening Serum
This is Dr. Chilukuri’s personal go-to pick for the best niacinamide serum. “A common theme in men’s skincare is that most men do not like having heavy or shiny products on their skin,” he says. “PCA SKIN’s Vitamin B3 Brightening Serum is hydrating, but not shiny or heavy, making it a good choice for improving men’s skin. In fact, this is the product I use daily after shaving.” And while this product is on the pricier side, it’s hard to argue with the solid Amazon rating (not to mention the doctor’s personal recommendation).
2. Paula’s Choice BOOST 10% Niacinamide Booster
With an impressive 10% niacinamide, this booster puts the ingredient front and center. You can apply the booster solo or mix it into your moisturizer.
