The Ordinary Acid Reviews

Recently Deciem updated their product pages to say that these acids should NOT be used in the same routine as other strong acids, EUK 134 (antioxidant) or Peptides which include Buffet, Buffet + Copper, Matrixyl and Argireline. If you´re ever unsure about which products can be used together, join the Facebook Group or ask Deciem.

Each product will take you through to its own review page where you can read lots more about the product and read reviews by the moderators of the Facebook Group and the Deciem Addicts.
