Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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.
Learn more about Glycerin1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse.
It is a:
- Humectant, drawing moisture into the skin
- Emollient, helping to soften skin
- Solvent, dispersing and stabilizing formulas
- Preservative booster, enhancing the antimicrobial activity of other preservatives
Allantoin 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 AllantoinHydrolyzed Hyaluronic Acid is a form of hyaluronic acid. It is created by the hydrolysis of hyaluronic acid with a high molecular weight. Once created, Hydrolyzed Hyaluronic Acid has a low molecular weight.
Low molecular weight HA has been shown to hydrate and increase elasticity of the skin. Increasing elasticity is also associated with reduction of wrinkle depth.
One study found topical low molecular weight hyaluronic acid may be considered for the treatment of rosacea in the adult population. However, we always recommend speaking with a professional about your skin concerns.
Hyaluronic acids are a humectant. This means they draw moisture from the air. Hyaluronic acids help moisturize, soothe, and protect the skin.

Learn more about Hydrolyzed Hyaluronic AcidHyaluronic acid is naturally found in healthy skin. It is a humectant, meaning it draws moisture to your skin.
This ingredient helps hydrate, soothe, and protect the skin.
What makes hyaluronic acid so hydrating? It has the capacity to bind or hold large amounts of water.
Fun fact: It is already naturally found in our bodies, such as the fluids of our eyes and our joints.
Studies find this ingredient to have anti-inflammatory and anti-microbial properties. This can help speed up wound-healing.
Hyaluronic acid can be irritating if the molecule has a low-molecular weight, or if the molecules are small.
One study found low-molecular weight hyaluronic acid to be pro-inflammatory, meaning some people may experience irritation. This is because our bodies use hyaluronic acid in the wound-healing process to signal to our bodies, via irritation, that something needs healing.
The same study found high-molecular weight hyaluronic acid to be anti-inflammatory.
These are some other common types of Hyaluronic Acid:
Learn more about Hyaluronic AcidSodium 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 HyaluronateSodium Hyaluronate Crosspolymer is a type of hyaluronic acid. In fact, it is modified version of hyaluronic acid.
The structure of Sodium Hyaluronate Crosspolymer allows it to stay in the skin's top layer for a longer period of time. This allows for even more hydration and humectant action than hyaluronic acid.
These are some other common types of Hyaluronic Acid:
Learn more about Sodium Hyaluronate CrosspolymerButylene 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.
Ethylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.
You might see Ethylhexylglycerin often paired with other preservatives such as phenoxyethanol. Ethylhexylglycerin has been found to increase the effectiveness of these other preservatives.

Hydrating and soothing just it kinda makes my pimples more red but in the morning it calms down
COSRX Hydrium Watery Toner 13 ingredients
This hydrates my skin very well and gives that “glass skin” look. It doesn’t feel sticky and absorbs quickly. But something in this is breaking me out, no idea which ingredient is the culprit. Gives me tiny pimples in different areas of my face each day I use it. I’m disappointed because it seems like a great product for those with sensitive acne prone skin like myself, but my skin just doesn’t Show more
This is so hydrating and great for my combination sensitive skin! It’s also way better than the isntree ultra low molecular toner in terms of hydration and results it provides. This toner did not make my face burn nor red in fact it calmed down my redness and provided me with a great amount of hydration, I also noticed how my makeup base was a lot more flawless than before. Not to mention this Show more
