The Ordinary Products, Targets & Conflicts

Here are all The Ordinary Products listed by their categories including what they do, when and where to use them in your skincare routine, plus all conflicting products.

You can find a chart with just The Ordinary conflicts here and a quick starter guide to The Ordinary here. Please always refer to the official Deciem regimen page and instructions of the products before using as the information is regularly updated.

The Ordinary Skincare Regimens

As you will see below, a lot of products have conflicts. If you’re new to skincare, I highly advise buying one of The Ordinary Skincare Regimens by Deciem, or ask Deciem for a regimen.

Many people get very excited when they first hear about The Ordinary and end up buying too many actives and products that conflict. Asking for a regimen will save you time and money.

The Chart

To keep the chart as simple as possible there are some abbreviations and conflicting products grouped under one name. Please read the following.

Conflicts with Peptides

If something says it conflicts with peptides this refers to all the peptides, Buffet, Buffet + Copper, Matrixyl and Argireline. Always check the instructions on the products.

Conflicts with Pure Vitamin C

If a product says it conflicts with pure vitamin c, this is practically all of the Vitamin c products. L-Ascorbic Acid Powder, Vitamin C 23% , Vitamin C 30%, Ethylated Ascorbic Acid, Ascorbic Acid 8% + Alpha Arbutin. The 3 Vitamin C products without conflicts are Magnesium Ascorbyl Phosphate, Tetraisopalmitate and Ascorbyl Glucoside.

Layering & Solutions

You can find lots of information on how to layer The Ordinary here. Understanding each solution is important as products need to be layered in a way they can penetrate the skin.

  • These products cause confusion and it´s no surprise why. I have seen Deciem recommend this before moisturiser and also after moisturiser.
