The Ordinary Products, Targets & Conflicts

Here are all The Ordinary products listed by their categories and includes targets, when to use them, where to add in your routine, and conflicts.

You can find a chart with just The Ordinary conflicts here and a new page with all the 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.

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 which 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 Acids

*Whilst not listed as conflicts, Deciem recommends to avoid Retinol, Pure Vitamin C and Direct Acids in the same routine to avoid irritation.

Azelaic Acid, Vitamin C 23% & 30%. Sometimes it is mentioned that these go before Natural Moisturising Factors and sometimes it is said to go after. Lately, Deciem has been advising for these to go after. See which way works for you.
