Ingredients Explained

These ingredients are found in both products.

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

Galactomyces Ferment Filtrate (GFF) is a yeast traditionally used to make the Japanese alcoholic beverage, sake.

GFF has moisturizing and antioxidant properties.

Studies show GFF improves our skin's natural moisturizing factors (NMF). Our NMF consists of many components that naturally moisturize our skin. Having healthy NMF keeps our skin plump, protected, and hydrated.

This ingredient tells our skin to create more filaggrin, an important component for NMF.

Filaggrin gathers all the structural proteins in our outer layer of skin and creates a tight barrier, helping to protect our skin against allergens and bacteria. This also helps prevent moisture loss.

Thanks to its antioxidant properties, GFF also protects our skin against oxidative stress and UV induced inflammation.

One study found GFF helped regulate sebum (oil) production and keratin in participants.

GFF may not be fungal-acne safe. We recommend speaking with a professional if you have concerns.

Many components of sake, such as GFF, are studied for their anti-aging benefits today. This is because sake brewers are known to have youthful hands.

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

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 also help thicken or stabilize a product.

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.

Skin Conditioning, Solvent

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. If you see this, drink a glass of water. Stay hydrated!

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 Show more

Nice serum for oily skin
It's nice on my skin and although at first it appears to darken my skin it clears up and leaves it smooth and shiny!
