This Skin Care Ingredient Has Almost No Negative Side Effects & It's In A Bunch Of Products Under $50

In general, it's safe to assume that something that seems like a cure-all will probably end up acting more more like a "cure nothing." But in the skin care world, there's one buzzy ingredient that seems to help with just enough different types of concerns to be legit: niacinamide, a form of vitamin B3. At the 2019 American Academy of Dermatology (AAD) conference earlier this spring— an annual event where experts in skin care get together to talk about the biggest new trends, treatments, and procedures in the industry — niacinamide was a hot topic of conversation, with several brands releasing new products that contain the vitamin.

As several dermatologists mentioned at the event, the main draw to the ingredient is the wide variety of skin concerns it treats, as well as its low level of risk for negative patient reactions. "Niacinamide is a key ingredient to treat age-related skin changes, acne, and skin discoloration," board certified-dermatologist Dr. Jeffrey Hsu, MD, tells Bustle. "It naturally calms the skin and provides dramatic skin brightening for a wide variety of skin types." Board-certified dermatologist Dr. Meghan Feely, MD, FAAD, seconds these claims, adding that "topical or oral niacinamide has been used to treat inflammatory skin conditions like acne vulgaris."

Basically, all the clinical trials that have been done so far (here's one on melasma and one on treating uneven skin tone more generally) have shown that this stuff can help with almost any minor skin concern, whether you're looking to treat acne or just add a little more brightness to your complexion. While you should always check with your dermatologist before adding any ingredient to your routine — especially if you're taking medication, Feely notes — the risks of side effects from using it are low. In fact, Joshua Zeichner, a director of cosmetic and clinical dermatology at Mount Sinai Hospital in New York City, told Allure,""Niacinamide is generally considered to be such a soothing ingredient that I do not have a conversation with most patients about side effects." Hsu echoes this, telling Bustle, "Niacinamide is an extremely well-tolerated product. There are very rare instances of irritation even with the use of high percentages."

In terms of working the ingredient into your own routine, Hsu recommends his patients start out with a product that has at least a 4% niacinamide concentration. And you don't really have to worry about it interacting poorly with your current skin care faves, either. Ivana Veljkovic, PhD, the vice president of research and development at PCA Skin, tells Bustle that the only time niacinamide doesn't work is if it's mixed with L-ascorbic acid (aka vitamin C) into one water-based product. "This does not happen if the ingredients are used at the same time on the skin from different products," she explains. "They mix well in the skin, but not in one water-based product."

If you're ready to add a little B3 into your skin care routine, here are all sorts of products that contain the stuff to try.

The Ordinary is known for making affordable versions of the trendiest skin care ingredients, so it's a great place to start when you want to try something new. The brand specifically calls out their version of niacinamide as being good for acne treatment.

This cult-favorite product sold out almost instantly after it launched in 2018, but now it's back and continuing to get rave reviews. Peach & Lily uses niacinamide in this serum for its brightening and antioxidant properties.

Paula's Choice products were meant to be mixed with what you're already using, making it easy to work them into your established skin care routine.

If you're looking for a more intense leap into vitamin B3 world, this professional product might be the way to go. It's pricier because it's made first and foremost for dermatologists, but it's also super effective at reducing redness and evening out skin tone.

Your undereyes can benefit from niacinamide, too: For this product, CeraVe includes the ingredient for its soothing effects.

Naturally, you can get your niacinamide from a sheet mask, too. This one has brightening effects, and the B3 helps even out skin tone.

Peace Out is probably best known for its first product, an acne treatment sticker. But now they have microneedling dark spot treatments, too — and, you guessed it, niacinamide is one of the main ingredients.

We love a sunscreen with skin care benefits! The niacinamide in this mineral SPF helps soothe your skin and keep it moisturized.

If you're not the type to do a 12-step routine every day, an easy way to work in extra benefits is to buy makeup that includes skin care ingredients. Wander's super creamy foundation contains niacinamide, so you'll get all the aforementioned perks of B3 even if you're doing a full look.
