There are currently 9 acids by The Ordinary. The newest acids are The Ordinary Salicylic Acid 2% which was finally reformulated after numerous years and the Salicylic Acid Anhydrous Solution.
How many acids should I buy?
I recommend that you only buy 1 or 2 acids because they have a lot of conflicts and only one acid should be used in a routine.

Patch Testing
Always patch test products, especially acids and do not rush into using them every day. Start slowly. Read the patch testing guide on The Ordinary website.
Can The Ordinary acids be used around the eyes?
Avoid the eye area when using acid. It is important to patch test these products before using them and to start using them slowly.
