Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Humectant, Masking, Skin Conditioning

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.
  • It has mild preservative properties.

Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.

Skin Conditioning, Solvent

1,2-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 
Emulsifying, Emulsion Stabilising, Gel Forming

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.

Humectant, Skin Conditioning

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:

HG! This is my favorite chemical exfoliant I have ever used! I will use this forever!
It's a watery toner but the next morning my face looks so nice and feels so smooth. It has helped with acne and doesn't sting if using on healthy skin. It also doesn't dry out my skin if I leave it on for a while before putting other products on.

Gently Exfoliates
I decided to try a leave-on exfoliator rather than an exfoliating cleanser because I noticed I kept getting irritation from exfoliating cleansers. This Cosrx one is really gentle and pleasant. It takes a few minutes for it to absorb into my skin, but afterwards I get very little irritation and my skin texture and pore appearance have definitely improved.

My favourite COSRX product. Pores appear smaller after a few hours. Was not expecting sebaceous filaments to disappear. I usually use one pump of liquid and put it directly on my T-zone and leave it to do its magic for about a few hours before applying moisturiser. (Putting moisturiser right after reduces its effectiveness from my personal experience.)
