What the gurus are saying

This serum calms redness and irritation with its 5% niacinamide; the zinc in it adds extra soothing power, and they work especially well together. The lightweight formula has no tack and feels smooth on skin, and it's fairly priced. If niacinamide isn't already part of your skincare routine, this is worth adding.

5 Underrated Skincare Ingredients For Healthy Skin & Slow Aging That Deserve More Hype | Dr. Idriss

"I've talked about Glossier's niacinamide and zinc serum for years, because it has the zinc PCA in it."

Best Serums of 2021 | Dr. Shereene Idriss

"My favorite niacinamide serum hands down is by Glossier. It is their Super Pure Niacinamide serum for twenty-eight dollars. The reason I love it is because they got it right. It is not only within the right percentage range—I think five percent niacinamide—it also has zinc, which helps to calm any sort of irritation. [...] And with niacinamide, it's like the perfect combination, and it has no cast, so I really, really do like this one."

"You have to look for niacinamide at five percent. I like this one by Glossier the Super Pure, it's also with zinc which is a great anti-inflammatory so they work well together. This is a nice one. This year you did good."

Tips + Tricks for Dark Spots, Discoloration, Hyperpigmentation, & Melasma | Dr. Shereene Idriss

"For niacinamide, Glossier has their five percent niacinamide mixed with zinc. It is a very good one that also has anti-inflammatory actions because of the zinc."

Teen Skincare Routine | Dr. Shereene Idriss

"The Glossier Super Pure Niacinamide and Zinc Serum is twenty-nine dollars and it is five percent niacinamide. The zinc has some anti-inflammatory properties that will calm redness with acne marks. If you're using niacinamide and exfoliating acid from Starface, you don't need this guy. If you don't have any niacinamide in your routine, then I would say invest in this. I hate the dropper, but you guys are going to feel like you're in chemistry class, so that is fine."

"They also have their Super Pure Clarifying Face Serum with niacinamide and zinc. Five percent zinc is not what you're gonna find in here. You're gonna find five percent [...] niacinamide, but it comes with zinc as well. For 29 dollars, with niacinamide and zinc, this is a good option."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Niacinamide

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
