The Ordinary Products, Targets & Conflicts Guide

Here are all The Ordinary products listed by their categories and includes what skin concerns they target, when to use them, where to add in your routine and also conflicts.

You can find a chart with all The Ordinary products you can and cannot mix. Please always refer to the official Deciem regimen page and instructions of the products before using as the information is regularly updated. Patch testing is highly recommended.

Ask Deciem for a regimen

Many people get very excited when they first hear about The Ordinary and end up buying too many products which conflict. To avoid this, it´s best to ask Deciem for a regimen that will save you time, stress, and money. You can find lots of routines at the bottom of this page. If you do want to put your own routine together, try going for the products which have no conflicts and only buy 1 maybe 2 from each category.

The Ordinary Retinols & Retinoids

  • whilst not listed as conflicts, Deciem recommend to avoid Retinol, Pure Vitamin C and Direct Acids in the same routine.
