A look at The Ordinary Niacinamide Powder

Deciem kindly sent a powder to myself and all the moderators of the Facebook Group before the launch date along with The Ordinary Hyaluronic Acid. The niacinamide powder needs to be mixed with water-based products and The Ordinary Hyaluronic Acid is perfect. It´s a cute little pot and comes with a little spoon. Warning! Keep the spoon in the box – I keep losing it.

The Niacinamide Powder should be sealed when you receive it (see photo above). Mix 1/4 of the spoon (this is a bit tricky) with 4 drops of a water-based product. I put the powder into the palm of my hands, added the Hyaluronic Acid, rubbed my palms together, and then applied to my face. There was no grittiness or soapiness, as long as you don´t use too much powder. It left skin feeling and looking really nice. I have also mixed with the Natural Moisturising Factors which was lovely too. I do find The Ordinary Hyaluronic Acid a bit sticky. Mixing with NMF was nicer.

If you like Niacinamide you will love this. If you like Niacinamide but dislike Zinc, then you will love this. For the price, it´s worth giving it a try but as always, be patient, be consistent and always read the instructions on the official product page.

Do not mix with formulations with a pH of 5 or lower. All PH levels can be found on every product page. See photo below.

What is The Ordinary Niacinamide Powder and what does it do?

Deciem says: Niacinamide, also known as Vitamin B3, is a well-studied, multi-faceted active ingredient that is renowned for its multiple benefits on the skin. It contributes to balancing visible sebum activity and supporting the production of components that play a central role in the structural and functional integrity of the skin. 

100% Niacinamide Powder from The Ordinary offers the most direct topical exposure of Niacinamide to target visible shine, enlarged pores, and irregular skin texture. This powder format offers a DIY experience that allows one to personalize their usage based on their preference. In comparison to the Niacinamide 10% + Zinc 1% solution, this powder format offers the user versatility in combining the benefits of Niacinamide with the benefits of other non-conflicting technologies (such as Peptide serums) to address multiple skin concerns at once.

Targets of Niacinamide Powder

  • Visible shine
  • Enlarged pores
  • Irregular skin texture⁣

When and how do I use The Ordinary Niacinamide Powder

  • Mix a quarter scoop of the spoon provided with 4 drops of the water-based treatment you are going to use, in the palm of your hand. Measuring a quarter of a spoon is quite tricky. It would have been better to make the spoon even smaller and just fill it.
  • Apply to the face in the morning and/or evening.
  • Avoid contact with eyes, if contact occurs rinse thoroughly with water.
  • Wash hands after handling.
  • Do not mix with formulations with a pH of 5 or lower. See photo above where you can find all The Ordinary pH levels.
  • If irritation occurs, rinse off, cease use, and consult a physician.
  • Use only as directed on unbroken skin.
  • Patch testing prior to use is advised.
  • Refer to The Ordinary website for a patch test guide
  • Keep out of reach of children.

What should I mix it with?

Deciem says: In its truest form, Niacinamide is readily water-soluble and dissolves in water-based products, such as serums and creams with ease.

You can mix this into any non-conflicting, water-based treatment, provided that the pH of the base is between 5.1 and 7.0. When it comes to the choice of a water-based base to mix with this formula, there are several options available within The Ordinary brand. These include the following:

You will notice Buffet isn’t listed because of its pH.

The Ordinary Niacinamide Reviews

Nia: I’m loving it. I just add a tiny bit to NIOD SDSM in my palm. Nicer than the 10%, no stickiness.

Jen: I really like it so far! I’ve tried with NMF – nice pairing. I didn’t personally like it paired with Hyaluronic Acid. Overall it’s too soon to know the effect but I’m enjoying using it and feeling like a chemist again 😁
Been using it in moisturiser on my arms and chest also.

Anna: Love or so far! Been using it every day. I’ve mixed it with an Hyaluronic Acid, a serum from Trader Joe’s (very similar consistency to TO’s HA) and just tried it with alpha arbutin. Was worried it might be gritty but both mixtures went immediately smooth and left a hydrated, silky feeling on my skin.

Tracy: Love love love it! Tried with HA this morning but it foamed up on my face. Tried it again with Argireline and it was awesome.


Questions ask and answered by Deciem on Social Media.

With the powder being a higher concentration could it cause irritation to sensitive skin? We would recommend trying test patches to see how your skin likes the formulation.

What is the main difference between the Powder and the serum? This offers the most direct topical exposure of Niacinamide. 

If my skin reacted badly to The Ordinary Niacinamide + Zinc, would the Powder be better? You may wish to explore this as an alternative! We recommend applying test patches to see how your skin likes the formulation. 

Does The Ordinary Niacinamide Powder cause skin irritation to sensitive skin? We would recommend trying a test patch to see how your skin likes the formulation.

Is this compatible with other actives like vitamin c, retinol, or exfoliating acids? We recommend avoiding use with products containing Ascorbic Acid.

Can I mix The Ordinary Niacinamide with Alpha Arbutin? We recommend alternating The Ordinary 100% Niacinamide Powder and The Ordinary Alpha Arbutin 2% + HA in different routines. 

Can I mix it with Glycolic Acid Toner? We recommend alternating The Ordinary Glycolic Acid 7% Toning Solution and The Ordinary 100% Niacinamide Powder in different routines. This is because it is unknown to us how much of the powder the customer will be dissolving into the direct acid serum. As such, we cannot judge with great precision to what extent the acidic environment may affect the chemical behavior of Niacinamide. Therefore, as a precaution, we have added Direct Acids as a conflict. In contrast, the Niacinamide 10% + Zinc 1% serum has a known amount/concentration of solubilized Niacinamide 

Can we mix it with Retinol and Retinoids? Yes

Could it be mixed with squalane oil? Yes

It is compatible with your hyaluronic acid serum? Yes
