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!

Drunk Elephant Protini Polypeptide Cream contains this as ingredient number 1.
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.

Drunk Elephant Protini Polypeptide Cream contains this as ingredient number 3.
Butylene 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.
Overall, Butylene Glycol is a safe and well-rounded ingredient. It is unlikely to irritate skin, and works well with pretty much all other ingredients.

Drunk Elephant Protini Polypeptide Cream contains this as ingredient number 37.
Palmitoyl Tetrapeptide-7 is a peptide. Peptides are building blocks for protein.
This ingredient consists of four amino acids and palmitic acid. These amino acids are arginine, proline, glutamine, and glycine.
This ingredient has many benefits. These benefits include boosting collagen production, fighting inflammation, and reversing UV damage.
By preventing our bodies from producing interleukins, Palmitoyl Tetrapeptide-7 helps fight inflammation. An interleukin is a chemical that signals to the body to produce an inflammatory response. Interleukin production is accelerated by UV radiation.
Palmitoyl Tetrapeptide-7 tells our body to create more collagen. Collagen is a protein that makes connective tissue. Boosting collagen production leads to a healthier skin barrier. Having a healthy skin barrier means having firm and hydrated skin.

Drunk Elephant Protini Polypeptide Cream contains this as ingredient number 17.
Palmitoyl Tripeptide-1 is a 3-amino acid peptide. Peptides are building blocks for protein.
Palmitoyl Tripeptide-1 is a signal peptide. This means it tells our skin to create collagen. Collagen is a protein that makes connective tissue. Boosting collagen production leads to a healthier skin barrier. Having a healthy skin barrier means having firm and hydrated skin.
Palmitoyl Tripeptide-1 can help reduce wrinkles and make the skin look more youthful.

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:

Drunk Elephant Protini Polypeptide Cream contains this as ingredient number 32.
Lecithin is a term for a group of substances found in plants, animals, and humans. They are made up of mixture of fatty acids. These fatty acids usually are a mixture of phosphoric acid's choline ester connected to stearic, oleic, and palmitic acids. Most lecithins are created from plant ingredients scuh as sunflower.
Lecithin is an emollient. Emollients help soften the skin and creates a barrier to keep moisture in.
As an emulsifier, it also helps prevent water and oil ingredients from separating. Lecithin can help ingredients be better absorbed by the skin. The phospholipids in Lecithin can produce liposomes. Liposomes help other ingredients get through the skin barrier.

Drunk Elephant Protini Polypeptide Cream contains this as ingredient number 36.
Polysorbate 20 is made by combining ethoxylation of sorbitan, ethylene oxide, and lauric acid. It is a mild cleansing agent, surfactant, and emulsifier.
As a surfactant, it helps collect dirt and oils for washing. Emulsifiers prevent oils and water from separating.
Polysorbate 20 also adds scent to a product. Since it is made using sorbitol, it has a sweet scent. Sorbitol can also be found in fruits such as apples and peaches.
The lauric acid used to create Polysorbate 20 is often derived from coconuts.
Polysorbate 20 may not be fungal acne safe.

Drunk Elephant Protini Polypeptide Cream contains this as ingredient number 44.
Carbomer is a polymer of acrylic acid. Its main role is to create gel consistency within products.
Carbomer is commonly found in many types of cosmetics products. It is found to be safe in concentrations up to 15%. However, a high amount of carbomer can cause pilling or balling up of products. Most products contain 1% of less of carbomer.

Drunk Elephant Protini Polypeptide Cream contains this as ingredient number 43.
Sodium Lactate is the sodium salt of lactic acid, an AHA. It is a humectant and used to adjust the pH of a product.
Sodium Lactate is part of our skin's NMF, or natural moisturizing factor. Our NMF is essential for the hydration of our top skin layers and plasticity of skin.
It also influences our skin's natural acid mantle and pH, which protects our skin from harmful bacteria.
Our NMF is formed from amino acids, lactic acid, sugars, minerals, peptides, and electrolytes. As we age, our NMF naturally depletes. Other sources of NMF depletion include harsh and drying ingredients such as denatured alcohol. Sodium lactate can help replenish our NMF, leading to more hydrated and plump skin.
High percentages of Sodium Lactate can have an exfoliating effect.
Sodium Lactate is produced from fermented sugar.

Drunk Elephant Protini Polypeptide Cream contains this as ingredient number 39.
Xanthan gum is used as a stabilizer and thickener within cosmetic products. It helps give products a sticky, thick feeling - preventing them from being too runny.
On the technical side of things, xanthan gum is a polysaccharide - a combination consisting of multiple sugar molecules bonded together.
Xanthan gum is a pretty common and great ingredient. It is a natural, non-toxic, non-irritating ingredient that is also commonly used in food products.

Drunk Elephant Protini Polypeptide Cream contains this as ingredient number 48.
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.

Drunk Elephant Protini Polypeptide Cream contains this as ingredient number 51.
Sodium Benzoate is a preservative. It's used in both cosmetic and food products to inhibit the growth of mold and bacteria. It is typically produced synthetically.
Both the US FDA and EU Health Committee have approved the use of sodium benzoate. In the US, levels of 0.1% (of the total product) are allowed.
Sodium benzoate works as a preservative by inhibiting the growth of bacteria inside of cells. It prevents the cell from fermenting a type of sugar using an enzyme called phosphofructokinase.
Sodium Benzoate is the salt of benzoic acid. Foods containing sodium benzoate include soda, salad dressings, condiments, fruit juices, wines, and snack foods.
Studies for using ascorbic acid and sodium benzoate in cosmetics are lacking, especially in skincare routines with multiple steps.
We always recommend speaking with a professional, such as a dermatologist, if you have any concerns.

Drunk Elephant Protini Polypeptide Cream contains this as ingredient number 55.
Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent germ and 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.

for the price point of this moisturizer i feel like i expected a lot more?
i mostly used this moisturizer at night paired with my tretinoin and i found that the 2 worked well with each other. it’s a really nice almost gel-like cream texture with a light fragrance. i found it a little hard to blend while my face was still damp which is when i usually apply moisturizer. i don’t feel like it did much for my skin but moisturize it.. lol definitely wouldn’t pay $70 for it again

i wish i didn’t like this
i just finished a free sample of this moisturizer, and i loved it. it wasn’t too thick or heavy at all, wore well under makeup, and didn’t pill.
it also costs $68 for a full size. while not entirely non-justifiable like La Mer or something, it’s still quite costly. perhaps in the future i’ll bite the bullet on a full size.
