UPDATE
There is a lot of confusion at the moment regarding Vitamin C derivatives & Niacinamide. Here´s a quick rundown;
- The Ordinary launched in 2016. The derivatives had no conflicts.
- There were even regimens with both products in the same routine.
- In 2020, when The Ordinary Niacinamide Powder was launched is when derivatives started to have conflicts.
- In November 2020, Deciem said not to use any of their vitamin c derivatives in the same routine as Niacinamide (serum & powder).
- March 2021 – the new website does not include conflicts mentioned in the video. I would continue to follow the November conflicts. (The Deciem regimen guide only says this on the niacinamide powder, not on the derivatives section.
What should I do?
You can check directly with Deciem or stick to the PDF's conflicts below for the time being. Deciem switched over to a new website on 1st March, and there are a few glitches.
The Ordinary Vitamin Cs
There are 8 The Ordinary Vitamin C products, and they vary in solutions, strengths and price. The cheapest vitamin c is 5.80$, and the most expensive is 18$.
How do I choose which vitamin c to use?
- If you're new to skincare, I would advise going for one of the derivatives.
- You might choose a particular vitamin based on its solution. If you already use an oil in your routine, you may wish to go for a water-based vitamin c or emulsion.
- Check your current routine to see which ones will not conflict.
- When do you want to use vitamin c? In the morning or evening?
- You may choose on price. All can be seen in $ as an example below.
Conflicts

Total Confusion With The Ordinary Vitamin Cs, Derivatives & Niacinamide
In November 2020, Deciem released a new video, A Guide to Vitamin C. There are many contradictions between the information in the video, answers on social media, and the new regimen guide. This is mainly between vitamin c derivatives and niacinamide.
From Deciem. We do not recommend combining Vitamin C (L-Ascorbic Acid, Ethylated L-Ascorbic Acid or Vitamin C Derivatives) with Niacinamide with Direct or Ethylated Vitamin C and Vitamin C Derivatives due to the formation of a salt complex that has the potential to reduce the integrity of both compounds. If you wish to combine both products into a regimen, we recommend using them on alternate days and/or nights.

The Ordinary Vitamin C Questions Answered by Deciem
Please note that there may be some contradicting answers here regarding conflicts. Please refer to the new chart above.
Can you mix The Ordinary Vitamin C 23% with The Ordinary Resveratrol & Ferulic Acid and Pycnogenol? Yes, you may!
I would like to know if I can mix The Ordinary L-Ascorbic Acid Powder with Alpha Arbutin. Yes you may, it's a great combination
If my skin can tolerate The Ordinary pure vitamin C powder (mixed in with an essence/toner product) and Matrixyl 10% in the same routine, is it still not recommended? Will they affect each other's effectiveness? We would recommend separating the products into two different routines for optimal results.
More FAQS
Can I use the L'Ascorbic Acid Powder combined/mixed with the hyaluronic acid serum? Yes you may.
Deciem advises using The Ordinary 23% as the last step as it's a suspension. What does this actually mean? A Suspension means the active is not dissolved and suspended instead for maximum stability. We suggest using Suspensions as the final step in a routine as they are thicker than a moisturizer or oil. We hope this helps to clarify
Which of The Ordinary Vitamin Cs would be best for a first-time user? Which Vitamin C is preferred? You may wish to begin with The Ordinary Ascorbyl Glucoside Solution 12%. This is a brightening, water-based serum with stabilized Vitamin C derivative to visibly target uneven skin tone, dullness, and signs of ageing.
Can I use The Ordinary Ascorbic Acid 8% + Alpha arbutin 2% and Lactic Acid 10% on the same routine? Ideally, the two should be separated into two different routines.
Is it ok to combine The Ordinary Ascorbyl Glucoside solution 12% after direct acids (aha or bha) in the same routine? And if yes, should there be a waiting period between the two as they differ in ph? You may indeed combine both products together. There is no need to wait a certain amount of time in between the application of products. As long as each product is massaged into the skin until absorption, you are welcome to apply the next product!
