Ingredients Side-by-side
Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Cyclopentasiloxane is a silicone used to improve texture and trap moisture. An easier name for this is D5.
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.
D5 is 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.

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.
