Niacinamide is such a popular ingredient because it does so much. This new niacinamide powder from The Ordinary has been created to offer the most direct topical exposure of Niacinamide.
The powder is so genius because Niacinamide is one of those ingredients that can be used alongside other active ingredients for optimal results. More info on that below.
What is The Ordinary 100% Niacinamide Powder?
- Powder format offers a DIY experience for personalised usage
- Provides the most direct topical exposure of Niacinamide
- Offers versatility in combining the benefits of Niacinamide other non-conflicting technologies to address multiple skin concerns at once
- Readily water-soluble
- Dissolves in water-based products, such as serums and creams, with ease
- Niacinamide works to reduce the appearance of blemishes, congestion, pores
- Great for brightening skin tone, strengthening the lipid barrier and retaining moisture
- Minimises redness, blotchiness and general inflammation
- Good for hyperpigmentation
- Regulates oil and prevents sebaceous glands from over working
- Protects against oxidative stress
- Boosts collagen and minimizes fine lines and wrinkles
As you can see, and probably already know, Niacinamide is quite the all-rounder and is a wonderful addition to many of your regular serums and moisturisers to boost their benefits.
What you can & can’t mix with The Ordinary 100% Niacinamide Powder
The main things to remember (as well as conflicts which I will get on to) is that niacinamide is water soluble. This means that the serums and moisturisers you want to mix it into have to have a water based component. If you are using straight oil, it won’t dissolve.
Mix it with
Deciem say that it can be mixed into any non-conflicting, water-based treatment, provided that the pH of the base is between 5.0 and 7.0.

The Ordinary Mixers
Options from The Ordinary include:
- Hyaluronic Acid 2% + B5*
- Natural Moisturizing Factors + HA*
- “Buffet” + Copper Peptides 1%*
- Matrixyl 10% + HA*
- Argireline Solution 10%*

Hylamide Mixers
Options from Hylamide include:
NIOD Mixers
Although I initially thought that you’d be able to mix with some NIOD staples, apparently this will be tricky as the PH of the product has to be below 5 and most are either 4.5ish or aren’t water based.
Retinol
There is some ressearch that suggests that Niacinamide helps the skin’s ability to tolerate high strength retinol. They are fine to use together, but you should leave five minutes before applying your retinol over the top.
Do Not Mix it with
- Do not mix with formulations with a pH of 5 or lower
- Niacinamide can affect integrity of the Vitamin C (L-Ascorbic Acid and/or Ethylated L-Ascorbic Acid) so avoid it in the same routine
Unsure where to start?
Studies have shown that you may get more out of niacinamide by using it alongside hyaluronic acid, as it believed to increase product absorption. So if you are at all unsure, start with Hyaluronic Acid 2% + B5*, Natural Moisturizing Factors + HA*, “Buffet” + Copper Peptides 1%*, Hylamide Low Molecular HA*, or Hylamide SubQ Skin*.
How to use it
To use the formula, mix a quarter scoop of the spoon provided with your chosen water-based treatment in the palm of your hand and apply to the skin in the morning and/or evening. Wash hands after handling.

My Review
As long as you choose the correct mixer (see above) the Niacinamide Powder blends in really easily and is super simple to use. A quarter scoop is quite a rough measurement, and I’m not sure how consistent I have been with quantities, but I don’t think it matters to much. I just mix a small amount with a water based serum with the correct pH (the above is Hylamide Low Molecular HA*,) and it’s super pleasant to use.
I get a slight tingle, which I really like, and it leaves my skin with an instant glow. This is such a convenient way to incorporate Niacinamide into your routine for extra brightening and skin smoothing.
Niacinamide Powder vs The Ordinary Niacinamide 10% + Zinc 1%
The Ordinary already have a Niacinamide serum so you might be wondering why you need this. Well, the new powder format offers more 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. This is also a great alternative for those who prefer not to use zinc.
Ordinary 100% Niacinamide Powder Release Date & Price
The new powder is available now at Deciem*.

Price for 20g is – £5.70
The Ordinary Niacinamide 10% + Zinc 1% currently sells one every three seconds globally, so Deciem are expecting the Niacinamide Powder to become a best-seller.

Looking forward to trying this. Not sure why they wouldn’t make a spoon which provides the exact quantity when filled up. Looking at the picture, it seems quite hard to figure out how much a quarter of that tiny scoop is! Thanks for the review.
yes the measurement is quite tricky but I think you will kind of work out what’s best for you as you go. x
