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. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

Dimethicone is a silicone used for making products smooth and silky. It also has the added benefit of sealing in hydration. The amount of dimethicone found in beauty products is considered safe and non-comedogenic, meaning it won't clog pores.

Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.
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.

Neutrogena Hydro Boost Water Gel US contains this as ingredient number 2.
Sodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective.
In small amounts, sodium hydroxide is considered safe to use. However, large amounts may cause chemical burns due to its high alkaline.
Your skin has a natural pH and acid mantle. This acid mantle helps prevent harmful bacteria from breaking through. The acid mantle also helps keep your skin hydrated.
"Alkaline" refers to a high pH level. A low pH level would be considered acidic.

Neutrogena Hydro Boost Water Gel US contains this as ingredient number 34.
Caprylyl Glycol is a humectant and emollient, meaning it attracts and preserves moisture.
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.

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.

These are some other common types of Hyaluronic Acid:

Pentylene glycol is typically used within a product to thicken it. It also adds a smooth, soft, and moisturizing feel to the product. It is naturally found in plants such as sugar beets.
The hydrophilic trait of Pentylene Glycol makes it a humectant. As a humectant, Pentylene Glycol helps draw moisture from the air to your skin. This can help keep your skin hydrated.
This property also makes Pentylene Glycol a great texture enhancer. It can help thicken or emulsify a product. Emulsifiers help stabilize a product. It does this by preventing certain ingredients from separating.
Pentylene Glycol also acts as a mild preservative and helps to keep a product microbe-free.
Some people may experience mild eye and skin irritation from Pentylene Glycol. We always recommend speaking with a professional about using this ingredient in your routine.
Pentylene Glycol has a low molecular weight and is part of the 1,2-glycol family.

Neutrogena Hydro Boost Water Gel US contains this as ingredient number 27.
Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).
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.
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 look more even.

Great mosturizer!
Tried this out of curiosity with my mom, both of us were pleased with our results. She has normal to dry skin and I have combo skin with fungal acne. She uses this everyday as soon as she gets out of the shower; without it her skin would feel dry as a desert. In my case, I put this on after using the Cetaphil daily facial cleanser. I know this product isn't fungal acne safe but I have combo skin, so I put it on the areas of my face that instead of having fungal acne, are kind of dry (mostly my cheeks, nose and neck). This moisturizer makes my skin feel refreshed, hydrated and healthy. It definitely has fragrance, but It's nice and light. I won't give it 5 stars just because it isn't fungal acne safe:)
Overrated moisturizer and it's expensive

Overrated moisturizer and it's expensive
I've used three tubs of this and my skin has gotten worse. The first two I noticed my skin gotten oilier than usual, but I want to trust the process like any other people. But I got a breakout on my third tub so I switched to other products and my skin has gotten so much better. This is definitely not for oily skin that needs sebum control..

I want to say I love it
This moisturizer isn’t even that bad, in fact it’s the first moisturizer that made my skin feel like a baby’s bum when I first got into the skincare world. It made my skin smooth within a month or so. It’s very lightweight and looks clear when you put it on. When you apply it, you might have to protect your face because it does take a couple of minutes to absorb into your skin. Though it was formulated for dry/extremely dry skin, I bought this product even though I have oily skin because I’ve seen many dermatologists recommend it to those with dehydrated oily skin or just oily skin in general. It smells good, but since it does have fragrance I would not recommend this to those with sensitive skin. I love the way it feels on my face but I feel like it just doesn’t pair with the other skincare products I own. I only use this occasionally when my skin feels a little dehydrated. Other than that, I’d totally recommend this to those with dehydrated oily skin and extremely dry skin!
