The Ordinary Niacinamide Conflicts

The Ordinary recommends avoiding using Niacinamide in the same routine as their Vitamin C products. You can find a list of The Ordinary conflicts here.

There is always conflicting advice when it comes to Niacinamide and Vitamin C. Some brands and people use them together without any issues. But this is what The Ordinary said in November 2020 regarding Niacinamide and vitamin C derivatives.

We do not recommend combining Vitamin C (L-Ascorbic Acid, Ethylated L-Ascorbic Acid, or Vitamin C Derivatives) with Niacinamide 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. 

What is the PAO of Niacinamide?

The period after opening Niacinamide is 12 months.

Why is The Ordinary Niacinamide foamy – is it normal?

This is one of the most common questions about Niacinamide. If you apply too much, it can be soapy. Apply smaller amounts at a time and make sure your skin is cleansed well with no residue left on your skin.

  • I think Niacinamide is wonderful. It really improves my skin texture. My pores just haven’t been clogged up since I started using it.
  • Love this! Been using it for three years now and wouldn’t stop.
  • I love the glow Niacinamide gives after every time I use it. But it’s breaking me out sometimes so I just finished the big bottle and didn’t repurchase it anymore.
  • Love it! This is one of the few out there without silicones. I don’t try other brands because too many have multi forms of silicone in them and more people than know are sensitive to silicones.
  • You do have to start slow in the beginning, but now I don’t even hesitate to add several drops. I find if you put it on damp skin it doesn’t pill, and pat it in if you have a tendency to pill.
  • I experience less hormonal acne and a better-feeling skin. Less texture.
  • As a person with dry skin and eczema, niacinamide is my number one product. I use two drops mixed into my moisturiser twice a day. It really helps to keep the eczema under control, and when I have a bad flare-up, I increase the dosage. Can’t live without it!
  • Jen @jamjarskingeek Niacinamide is my absolute favourite product from The Ordinary. It’s a multi-purpose gem that supports my skin barrier, helps with pigmentation, and keeps my oily skin in check. I wouldn’t be without it and love the new large size
  • Niacinamide has changed my life.
  • Niacinamide has really helped. Less redness and balanced sebum production.
  • I love Niacinamide. It has been great for my rosacea.
  • My skin has gone from ‘dry’ to ‘normal’ even with prescription-strength Retin A. It’s helped to keep my skin moisturized. I’m obsessed with this product, and I use it night and day.
  • I’ve been using The Ordinary’s Niacinamide for 2 yrs now. My skin loves it. I have oily skin prone to breakouts, and this makes my skin look amazing.
  • Niacinamide has tightened my pores and helped with blemishes.

The Ordinary Niacinamide Fakes – How to spot a fake Niacinamide

There are counterfeit products, and Niacinamide seems to be one of the common ones. The best advice I can give you is to buy through Deciem or one of their authorized stockists.

If you are shipping to a country with free shipping over 250$ shipping, I would recommend getting a few friends together and making a large order. Avoid Shopee, Amazon, and eBay.
