Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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.
Overall, Butylene Glycol is a safe and well-rounded ingredient. It is unlikely to irritate skin, and works well with pretty much all other ingredients.
Pentylene glycol is typically used within a product to thicken it. It also adds a smooth, soft, and moisturizing feel to the product. It is naturally found in plants such as sugar beets.
The hydrophilic trait of Pentylene Glycol makes it a humectant. As a humectant, Pentylene Glycol helps draw moisture from the air to your skin. This can help keep your skin hydrated.
This property also makes Pentylene Glycol a great texture enhancer. It can help thicken or emulsify a product. Emulsifiers help stabilize a product. It does this by preventing certain ingredients from separating.
Pentylene Glycol also acts as a mild preservative and helps to keep a product microbe-free.
Some people may experience mild eye and skin irritation from Pentylene Glycol. We always recommend speaking with a professional about using this ingredient in your routine.
Pentylene Glycol has a low molecular weight and is part of the 1,2-glycol family.

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.
