Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Sodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.
Like hyaluronic acid, it is great at holding water and acts as a humectant. This makes it a great skin hydrating ingredient.
Sodium Hyaluronate is naturally occurring in our bodies and is mostly found in eye fluid and joints.
These are some other common types of Hyaluronic Acid:

It is a common ingredient in many products, especially those designed to hydrate skin. The primary benefits are retaining moisture, skin softening, and promoting a healthy skin barrier.
Though Caprylyl Glycol is an alcohol derived from fatty acids, it is not the kind that can dry out skin.
This ingredient is also used as a preservative to extend the life of products. It has slight antimicrobial properties.

Expensive, and it did nothing for me - I didn't notice any soothing or red reduction from my seb derm after using it for more than 1 year. My combination skin still felt tight in the winter, and oily in the summer. Sadly, this is an anecdotal serum.
This serum deeply hydrates my skin. It’s quite thick and sticky so I would recommend applying it only during the night routine. It’s perfect when my skin needs to be moisturized. My acne-prone skin did not have any problem with it.
