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 WaterPhenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.
It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
Persea Gratissima Oil is also known as avocado oil.
Avocado Oil has antioxidant properties. It is mostly made up of the glycerides of fatty acids. About 67% of these fatty acids is made up of oleic acid. Palmitic acid and linoleic acid are also present.
These fatty acids help hydrate and soften the skin. It may increase collagen content in the skin. Collagen helps keep your skin plump and firm. This ingredient helps reduce inflammation and has not shown to clog pores.
This ingredient may not be fungal-acne safe due to its high fatty acid content.
Avocados also have B vitamins, vitamin K, vitamin C, vitamin E, and potassium.
Learn more about Persea Gratissima OilButylene Glycol (or BG) is used within cosmetic products for a few different reasons:
- It is a solvent, meaning that it helps to dissolve other ingredients. This also enhances the absorption of the product into one's skin.
- It is a humectant, which means that it helps attract moisture into the skin.
- It helps improve product application.
- It has mild preservative properties.
Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).
As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and even out skin tone.
If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.

Have used this for a number of years and recently made a switch to Shisedo’s eye cream. I’ll be going back to Kiehls when I’ve finished it as it’s honestly the most nourishing eye cream out there. It doesn’t migrate into the eye and is super rich and hydrating. Just make sure your fingers are dry when applying otherwise it just slips around and doesn’t sink into the skin.
very nice eye cream, helps with my under-eye darkness and sensitive skin. a different eye cream i tried gave me millia so i'm hoping this one doesn't do the same thing. i think it's worth it to spend money on this, than to spend it on low-end products. i use this on top of my hyaluronic acid serum from l'oreal.
