Ingredients Explained

These ingredients are found in both products.

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

1
What it does: Skin Conditioning, Solvent
Community Rating: Loved

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!

Sk-II Facial Treatment Essence (Pitera Essence) Original contains this as ingredient number 4.

Kiehl's Vital Skin-Strengthening Hyaluronic Acid Super Serum contains this as ingredient number 1.

2
What it does: Masking, Preservative
Community Rating: Disliked

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.

IT'S EXPENSIVE BUT WORTH THE MONEY!!!!
I'm the kind of person who is willing to go all out and drop some money for good skincare if I know I will use up every drop and love it. I've tried a lot of snail mucin products (my oily acne-prone skin LOVES it) and this one is different! I've tried the COSRX and the Peach Slices and both don't compare to this. Peach Slices have a similar texture while COSRX has a similar result to the SK-II. However, I will say that the SK-II got rid of all my redness and significantly improved my acne and every time I run out I always notice a difference in my skin whenever I don't have it in my routine. The price tag is a little intimidating but there are more reasonable options on Stylevana and Yesstyle.
