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. If you see this, drink a glass of water. Stay hydrated!
Learn more about WaterAzelaic acid is a naturally occurring acid derived from grains. This ingredient is effective in treating acne, rosacea, and other skin conditions.
It has been shown to reduce the growth of acne-causing bacteria and helps reduce inflammation. On top of that, it helps reduce the production of sebum and unclog pores.
Azelaic Acid also has antioxidant properties. Antioxidants protect our skin cells from free-radical damage.
One of the main benefits of azelaic acid is that it is gentle and well-tolerated by most people.
Fun fact: The lab-created form of azelaic acid is typically used within cosmetic products for its shelf-stability.
Learn more about Azelaic AcidCyclopentasiloxane, or D5, is a silicone used to improve texture of products and trap moisture.
D5 is considered lightweight and volatile. Volatile means it evaporates quickly after application. Once evaporated, D5 leaves a thin barrier that helps keep skin hydrated.
It is also an emollient. Emollients help soften the skin and prevent water loss. Silicones create a silky texture in products. D5 helps other ingredients become more spreadable.
Studies show D5 is safe to use in skincare products. We recommend speaking with a skincare professional if you have concerns.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.

Paula's Choice 10% Azelaic Acid Booster 21 ingredients
Did nothing for my fungal acne. Actually did nothing at all.
(Compared to my cheap no-name Russian brand Azelaic acid cream which worked wonders).
Paula's Choice at it again with cetearyl alcohol high up on the ingredient list. I'm disappointed by their ingredients fairly consistently now.
