The Ordinary Acids Guide

There are 9 acids in The Ordinary Collection and below you can find reviews and lots more information on each of them to help you choose which one is best for you.

I highly recommend that you do not buy too many acids as they have many conflicts and they can really damage the skin if used incorrectly. Please always check conflicts and products you can and cannot use together here.

Patch Testing

It is highly recommended to patch test acids before using. Please refer to the official patch testing guide on The Ordinary website.

Avoid the eye area when using The Ordinary acids. It is extremely important to patch test these products, particular AHA 30% and Salicylic Acid.
