Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

Curology Custom RX Azelaic acid 8% Tranexamic acid 5% Niacinamide 4% contains this as ingredient number 7.
Polyacrylamide is a synthetic polymer. It is used to stabilize products and bind ingredients. When hydrated, Polyacrylamide forms a soft gel.
Polyacrylamide is low-toxicity. If source properly, it is deemed safe to use in cosmetics.
It should be noted the precursor to Polyacrylamide is acrylamide. Acrylamide is a carcinogen. Most reputable sources of Polyacrylamide will screen for residual acrylamide to make sure the count is in a safe range. Acrylamide is not able to be absorbed through the skin.
We recommend speaking with a professional if you have concerns.
