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 WaterAllantoin plays a role in soothing and moisturizing the skin. Because of this, it is often added to products with strong active ingredients.
Some studies have shown this ingredient can promote wound healing with higher concentrations.
Allantoin is derived from the comfrey plant but produced synthetically for cosmetic products to ensure purity.
Learn more about AllantoinSodium 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:
Learn more about Sodium HyaluronateButylene 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.
Disodium EDTA plays a role in making products more stable by aiding other preservatives.
It is a chelating agent, meaning it neutralizes metal ions that may be found in a product.
Disodium EDTA is a salt of edetic acid and is found to be safe in cosmetic ingredients.
Learn more about Disodium EDTACaprylyl 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.

Here's what our community thinks
COSRX The 6 Peptide Skin Booster Serum 44 ingredients
I was breaking out for 3 months and had no idea what was going on. Then my mom mentioned she’s getting small bumps around her jawline from another peptide serum (Skin1004) and it clicked. Stopped using it week ago and didn’t get a single pimple.
Didn’t see any positive results.
No difference seen so far as i started last week, goes on nice and absorbs fast, no scent whatsoever and pretty hydrating
EDIT: GAVE ME CLOSED COMONDONES LIKE THE OTHER REVIEWER. DONT USE.
