Ingredients Explained

These ingredients are found in both products.

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

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 
Humectant, Masking, Skin Conditioning

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

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

Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.

Emulsion Stabilising, Gel Forming

Carbomer is a polymer of acrylic acid. Its main role is to create a gel consistency.

A high amount of carbomer can cause pilling or balling up of products. Don't worry, most products contain 1% or less of carbomer.

Absorbent, Emollient, Emulsion Stabilising

Sodium Polyacrylate is the sodium salt of polyacrylic acid. It is used as an absorber, emollient, and stabilizer.

This ingredient is a super-absorbent polymer - meaning it can absorb 100 to 1000 times its mass in water. As an emollient, Sodium Polyacrylate helps soften and soothe skin. Emollients work by creating a barrier to trap moisture in. This helps keep your skin hydrated.

I got a sample of this and saw that it was FA safe and had no comedogenic or irritating ingredients so I tried it out. Only used it 4 times, but it was pretty obvious what a powerful humectant beta-glucan is. Just pure hydration and calm. Definitely buying the full size if I need the extra hydration. In this regard, it beats the skin1004 madagascar centella ampoule! (Still love that for beneficial Show more

Very hydrating, my must have product
Wow. I regret not buying this earlier. It's a somewhat thick serum that's very moisturizing and absorbs nicely into the skin,depending how much you use. I go heavy on this and put a full dropper on my face and it takes a while but it does sink in.

It has helped with my rosacea flareups and dry patches.

It's niacinamide free so it's a great hydrating Show more

this snail mucin essence really is one of the best ones out there— it's a holy grail. this product was my very first impression of cosrx, and the short ingredient list is very surprising with how effective it is. i've been using it for about a year now, and it's become a staple in my routine. after my first couple weeks of use, a lot of my dark spots disappeared and calmed down my hormonal acne & Show more

This ruined my face! I didn’t know that my dust mite allergy also made me allergic to this. I used it for five months and everything seemed fine, but then I started to get a goatee of fungal acne with big red patches. I’d also been getting a lot of big pimples in my hairline from it. It’s taken me months to understand what happened and to soothe my sad skin. Be warned not to jump off the bridge Show more
