body{margin-left:12%}Product ReviewsRated 4.17 out of 5 stars150 ReviewsMost Helpful Positive ReviewI mix this...I mix this with my face moisturizer with no adverse effects. It does exactly what my prior niacinamide serum plus face cream routine did and comes cheaper. I have one question tho: can i mix a big batch with my body lotion and use it over a time (how long?) or does it turn inactive after a while after mixing and therefore should be mixed immediately before application each time? DECIEM Response: Thanks so much for your review! We're glad to hear you're loving our 100% Niacinamide Powder. We recommend mixing per application ❤.Most Helpful Critical ReviewExpired July 2021. Ordered in October 21 :(I love The Ordinary's Niacinimide powder but I bought the latest batch a week ago and apparently it has already expired. Still, I mix it with my cerave in hopes that some of the magic remains. :( The Ordinary! Take note, I've noticed a lot of reviews commenting on short expiry dates.Reviewed by 150 customersGood product4Chloe from undisclosedThe powders smell is not very pleasant, however other than that its great!Its okay..3Sylvie13 from undisclosedI bought this and right away was confused by the directions. It did not come with the scoop it said was provided so I had to wing how much to use, which I dont like. Based on this, I will continue to use until my face either doesn't change or goes flaming red. Thanks The Ordinary, you are exactly that.The appearance of white powder on the skin1Paris from undisclosedUnfortunately, I always have this problem with white powder (plz see attached) on my face after using 100% niacinamide powder, I mix this powder well in the palm of my hand with 4-5 drops of hyaluronic acid 2%+B5. But After applying it, this product leaves behind a white powder. Please advise me, what is the cause of this problem? ThanksHoly Grail Product5Jan from MinnesotaAfter using the niacinamide serum for many years and it helping clear my skin, I wanted more of it. And I use about half a scoop and I've used it for almost 2 years now and nothing bad has happened and my skin loves it. Also I see ppl complaining about not being able to use all of it before it expires. You can use it in other things, dissolve a bunch in your serums or toners or I make my own toners sometimes and I add a bunch of it in there. It's versatile! Right now and probably forever I mix it with the snail musin serum from CosRx.Cleared up my skin so fast5Sophie from Wausau,WiI got this 2 days before homecoming and it cleared up my skin so well in little time I use the tiniest amount less than it says to use and mixed it with my face cleanser that never worked that good. I will never stop buying this product and has such a good price too!expiry date5HOUDA from undisclosedI bought niacinamide powder 20 g from Morocco, the expiry date in both the coverage and the jar was removed I think it is expired. my questions are : It is possible to track the product given that I can't find the batch number? Could the ordinary niacinamide powder be used even if the product is expired? it will be safe and still efficient?My Go-To Niacinamide Product!5raie from undisclosedI've been using TO's 100% Niacinamide Powder for a year or two now, and it's absolutely wonderful. I used to be a huge fan of the Niacinamide + Zinc serum, but decided to give this product a try when it first came out, and have not gone back. When I first purchased this, I initially mixed it in with my moisturizer (both AM/PM), or with TO's Marine Hyaluronics, and both worked really well. I have since then switched over to combining it with COSRX Advanced Snail Mucin Power Essence and still use it both AM/PM. The extra hydration and power of niacinamide have been working well together for me. I highly recommend this product, especially if you're looking to combining two steps in your skincare routine!Spoon5K from undisclosedWhy wouldn't the scoop be the exact measurement instead of messing with it making sure it's a quarter of a scoop.. seems like you'll use too much or take longer than necessary playing with an extra step. I don't know. I like to be sure of dose.Expired long before I could use2Terri from undisclosedThis product expired very quickly from purchase date and I had to throw away a lot of product. Disappointing. Just wanted to pass on this information and the "contact us" is very difficult to use. Also, disappointing. Thank you5% Niacinamide at your fingertips5AlexW from undisclosed7 level scoops is about 1.5g. When added to 30mls serum of your choice (I choose buffet+copper) then you have the clinically recommended dose (5%) of niacinamide to enjoy. No irritation or dryness. Dissolves easily. What's not to like.5% Niacinamide at your fingertips5AlexW from undisclosed7 level scoops is about 1.5g.

I've been pretty religious with my Vitamin A, glycolic and retinolic but I've never really been satisfied with the smoothness of my skin. I have large pores, and your basic ruddy bumpy skin. I started adding this to my glycolic acid and I find my skin to be noticeably smoother and the pores seem quite a bit smaller.I love it5Melissa from undisclosedI love it but be careful to use just a little bit because too much is irritating. I can use it everyday if it's just a little :) It helps me regulate production sebum blend in the acid hyaluronic serumI love it5Melissa from undisclosedI love it but be careful to use just a little bit because too much is irritating.

This is a part of my daily regimen and mix it with The Buffet with Copper Peptides. I apply it after cleansing and before The Hyralonic Acid HA moisturizer. It has helped in saving my skin! I haven't had any major acne since using this.Keeps my acne at bay!5Artmarker from undisclosedAs am was going through menopause, my adult acne kicked in with a vengeance (worse than when I was a teen).

Milia, blackheads, lines… you name it, it's made such a difference and the price point isn't one you can argue w. Anyway, I love all things the ordinary and am down to try something new. I saw this and had to have it. Once it came, I really hesitated bc I didn't quite know what to do with it, even after reading the instructions and previous reviews. Plus, I loved the liquid so much, I felt stuck. Anyways, I ended up mixing it with the hyaluronic acid serum that I keep in the freezer. OMG. Omg omg Omgggg. Every single issue with my skin has been addressed 100%. Like, I can't EVEN. I am in love and that's it! Never going back! It's true what others have said about the spoon, even tho it's superrrrrr small you still only need 1/3 of it. making an even smaller spoon would be great but it's a small thing in the scheme of it all. And yes, the jar IS NOT FILLED to the top but seriously, you need such a small amount I can't imagine going thru this quickly. I use it only at night as I prefer to use minimal products during the day under my make up: strictly face wash, toner and moisturizer. But you could even use it every other night. This is a game changer like I've never seen! It's out of stock now but set your alerts people bc it's worth the wait and every penny!Unexpected Holy Grail5MissMea from undisclosedI didn't expect to like this as much as I do or for it to become an absolute staple in my regime like it has. For reference I'm mid 40s. My skin has spent a lot of time in the sun over the years due to work and extracurricular activities. I was unhappy with the texture / uneven tone and literally spending hundreds of dollars to find a product to correct this. Then this game changer came along. I apply it nightly. I'm not really sure what people are complaining about with the scoop, it isn't that serious people just start with a little bit. I scoop a bit into my palm, dab a bit of moisturizer in and gently massage it into my skin. I rotate through a lot of other products in my routine but this has had no bad effects when used with any of them. My skin GLOWS in the morning. It feels plumped up and happy. My texture evened out remarkably. And it makes my skin so soft. I feel like this literally took years off my face (I know I sound like I own stock but I'm sick of wasting money on products that don't work). I love it so much I also mix it with my body lotion after showering (one reason why I love the larger scoop). Nothing I have ever tried including face products costing well over $200 have made such a noticeable difference. This is my third purchase. The jar has a tremendous amount of product. Worth every cent. I give this to all my girls as gifts and everyone is hooked. At this price it is absolutely worth a shot. My favorite product of all time.Unexpected Holy Grail5MissMea from undisclosedI didn't expect to like this as much as I do or for it to become an absolute staple in my regime like it has.

When I realised that the expiry date is ridiculously short, I gave my sister half to put in an empty bottle, and we share it. I also now mix it into my body lotion. I would be a lot more annoyed at the awkward packaging size/expiry if this wasn't such an affordable amazing product.Great product other than packaging/expiry4Stef from undisclosedI love using this product and mixing it in with my serums at night- my skin is so much smoother and my pores are smaller (holy grail product for me tbh).
