Why Do The Ordinary Products Conflict?
Can cause irritation – Using too many active ingredients together can irritate sensitive skin.
Reduce effectiveness – Some ingredients work less effectively when combined.
They work better separately – Many conflicting products can still be used safely by applying one in the morning and one in the evening or on alternate days.
So before you excitedly open all your bottles and splash your potions on your face, make sure you read The Ordinary Conflicts Guide first!

The Ordinary Conflicts – Product you should not use together
You can use these products in alternate routines, for example, using your peptide in the morning and acids at night or on alternate days.
Experience from our Deciem Community
From years of running Deciem Chat Room, one of the biggest mistakes I see is people buying too many active ingredients at once. Most people get better results by keeping their routine simple and introducing products gradually.
The Ordinary Conflicts – Conflicting Products
There is much conflicting information online about skincare conflicts and ingredients you should and shouldn´t mix, coming from brands and influencers. If you´re new to skincare, I recommend following the advice from The Ordinary. They consistently test and update information, so it´s always a good idea to double-check conflicts by using the compatibility tool on The Ordinary page before using it.
Some of the more recent updates regarding The Ordinary conflicts are;
- Avoid Peptides & Resveratrol & Ferulic Acid in the same routine
- Use only one antioxidant in a routine.
- Avoid niacinamide with all Vitamin C.
Patch-Testing
Patch-test each product before use and when you start layering products. Why? because if you start by using numerous products and have a reaction, you will not know which product caused it.
