Glossier Super Pure Niacinamide and Zinc Serum Review

If there’s one skincare ingredient that I see on the internet more than Hyaluronic Acid these days it’s Niacinamide. It seems like every skincare brand has one these days, from The Ordinary to Fourth Ray Beauty. Glossier has one too! The Glossier Super Pure Niacinamide & Zinc Serum made its way into my shopping cart when I saw that they increased the size of their serums to a full ounce for the same price.

I’ve been thinking about trying the Glossier Vitamin C Serum as well but with skincare it’s best to move slow. You don’t want to introduce too many new products at once! My skincare routine has been fairly consistent lately. Now that it’s summer I don’t really need a plethora of different products layered on my skin to keep it hydrated anymore. With hydration in check I decided to try Super Pure to target another skin concern of mine — Acne.

Does your skin feel stressed? Out of balance, oily, or on the verge of a breakout…whatever it is, consider the 5% Niacinamide and Zinc PCA in Super Pure your new best friends. — Glossier

The Glossier Super Pure Niacinamide & Zinc Serum works to balance skin over time by targeting uneven texture and reducing oiliness. Super Pure retails for $35CAD and contains 1oz of serum.

My skin always becomes a little bit more oily in the Summer even though it leans dry. My chin has been a problem area for me lately with larger pores and acne popping up every few days. The pores on my cheeks have also become more noticeable lately so I was hoping this serum would help reduce their appearance.

What is Niacinamide?

According to Paula’s Choice, my preferred source for skincare ingredients (because they cite their sources) Niacinamide — or Vitamin B3 — helps to minimize enlarged pores and “improve the appearance of uneven skin tone, fine lines, dullness and a weakened skin surface.” The entry goes on to explain that Niacinamide is also to help repair damage from UV light and environmental pollutants.

It’s a myth that Niacinamide and Vitamin C products can’t be worn together, they actually are quite compatible. I’ve been pairing my Super Pure serum with The Ordinary’s Vitamin C 23% suspension with fairly good results.

What is Zinc PCA?

Glossier Super Pure Serum contains Zinc PCA to help reduce excess sebum protection. And according to Paula’s Choice Zinc PCA is “a synthetic skin-conditioning ingredient derived from zinc. Research has shown it has anti-aging benefits due to its ability to thwart destructive enzymes in skin that can damage its surface and lead to an aged, wrinkled appearance.” [Source]

Glossier Super Pure 5% Niacinamide Serum packaging


I love a good dropper bottle! It’s my preferred packaging for anything serum related. There’s something so sophisticated about a glass dropper bottle. It feels grown up and downright Science-y. This bottle is completely clear so you can easily see how much clear blue serum is left inside.

Application & Texture

The Glossier Super Pure Serum is almost water like in consistency. It’s a touch more viscous than water and feels slightly slippery to the touch. As the bottle suggests I use the dropper to dispense about 3 drops into my hands before pressing the serum into my face. 3-4 drops is all I need to apply the serum to my T Zone and the parts of my cheeks where my pores show.

Super Pure absorbs pretty fast and doesn’t feel sticky on my face or heavy once it’s applied. I like that there’s no silicone type feeling and that my products later on top of it without pilling.

I have myself eight weeks to test the Glossier Super Pure Niacinamide + Zinc Serum. The participants in the clinical trial for this product were also given eight weeks to I thought it was only fair. It irks me when I see bloggers/youtubers review skincare after only a week of testing. It takes time for your skin to react to a new product and to see any results!

did see results using this serum, but they happened slowly. So slowly in fact that I didn’t even notice that the pores on my nose had cleared up until I took a break from the Super Pure Serum for a week. That’s when I noticed the changes in my skin the most.

I didn’t realize just how much Glossier Super Pure was preventing my pores from getting extra clogged and gross. Their size is definitely a little smaller with this serum in my routine but they aren’t invisible. With the addition of Super Pure back into my routine my nose is at least looking a little clearer. My chin still has problem spots but I’m breaking out less than I was before.

No skincare product is a miracle worker. My skin is looking better these days but I still break out and I still have problem spots. It’s nice to have a little bit of help with those spots though!

Have you tried Glossier Super Pure Niacinamide + Zinc Serum?

I would love to try some of the less expensive Niacinamide serums out there and compare them with Glossier Super Pure. I like the results I’ve seen from adding Super Pure into my skincare routine but $35 is a lot to spend on a regular basis. The Fourth Ray Beauty Niacinamide serum is only $15USD and The Ordinary’s is $5.90CAD so if one of those works just as well that would be amazing!

Thank you for reading x

    I love a glass dropper, too, lol so classy! This serum is so pretty! I’ve been having issues with bumps, acne, & pores on my cheeks lately, too. Have you noticed those going down or just your nose has become clearer?

      Glass droppers feel so fancy! I only really noticed an improvement on my nose, but my pores on my cheeks aren’t too bad right now. I think everyone’s skin is different so it’s hard to know how it will react

    Great review! I love that you explained the ingredients because I hadnt heard of niacinamide before. It may be a good product to try considering I also have oily skin with some dry patches but ill look more into it to make sure it would be the right product to use.

      I hadn’t either! I need a skincare dictionary, seriously! I’d like to try a few of the less expensive serums and see if they have good results, because the Glossier one isn’t cheap. If you do end up trying it I’d love to hear how niacinamide works for you!

      • August 14, 2019 / 8:39 am

        I have a bunch of serums in mind as well, both high end and drugstore so we will see which I end up picking lol

    Great review! Love how comprehensive you were in explaining everything. Since you’re looking for something more affordable – does The Ordinary do a niacinamide? Personally, I wouldn’t mind spending $35 if the product really works and I like it. I’ve definitely spent a lot more on skincare, truth be told!

      I’m so glad you enjoyed this review! Yes the ordinary has one too! I’d love to compare and see if it works just as well as the Glossier niacinamide 🙂 That’s true, some serums can be $50+ so that puts it in perspective!

      • August 13, 2019 / 9:36 am

        Do a comparison post! I don’t do nearly as many of those as I should, but when I have they get so much traffic!

        • August 13, 2019 / 12:18 pm

          Maybe once I pick up another serum or two 🙂 For now I have a ton of skincare to test!

          • August 13, 2019 / 2:44 pm

            Me too. It’s gotten a bit outta control lately, not sure how that happened!
