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.

The best essence that I've ever had! Other than that, this makes my textured (bumps) forehead become less and smooth.
Update! After a month of using this, this product actually dried my skin out, it's giving me the painful acne, and breakouts weekly. It is not worth it, I don't see any progress at all, not worth it.
Update! It was my mistake for using the Neutrogena Gel Cleanser, and also Show more
This is just glorious. I use it on my daily routine, am and pm after washing and toning, on my face and neck. Very hydrating and makes quite the difference in how the rest of my serums soak into my skin. I have never had any issues with makeup over it so far, no pilling no matter what I use after. It has made my skin glow and simply look lovely. One product I never want to be without. I would Show more
