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!

A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.
As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.
Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.
Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.
In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.
This ingredient is organic, colorless, odorless, and non-toxic.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.
Learn more about GlycerinCaprylyl Glycol is a humectant and emollient, meaning it attracts and preserves moisture.

Learn more about Caprylyl GlycolArginine is an amino acid that is important for human development. Your body uses is it to produce hair keratin and skin collagen.

I bought this when my skin barrier was damaged, hoping it would calm the irritation i have, but it made things worse. This serum broke me out badly. I think it might be due to the high concentration of ceramides, but it also contains PHA, so I’m not sure if it was a breakout or purging. However, when I stopped using it, my skin returned to normal. As a barrier serum, I don’t think this is Show more
THANK GOD for this serum. i’m currently using tretinoin and I’ve tried different serums and they wouldn’t do much or would irritate me to the point of breaking out (the ordinary niacinamide serum :/) i recently tried to divert and go back to a niacinamide serum but it did as it’s done to me before and irritated me and broke me out but this serum saved me. Im on my third bottle!

I have no idea what the hype is. Sure the ingredients sound fine but it’s anything but hydrating and pretty sure it broke my skin barrier or maybe it doesn’t pair well with basic ingredients and trust I know it has copper peptides so I know what not to pair it with. Still my face after a week felt on fire… still can’t find the right routine because I read and fall for fads and “reviews”. if you Show more
Been using around 3 weeks. Feels hydrating and leaves skin glowy and less tight after use. I haven’t noticed overall increased skin hydration when not using but maybe I haven’t used it long enough yet.
