About the product

What Is It:

Formulated with 10% galactomyces ferment filtrate, this alcohol-free toner hydrates and fortifies the skin barrier to prevent moisture loss. Galactomyces is a type of yeast lauded for its brightening, hydrating, softening, and antioxidant properties; its fermentation makes it better able to penetrate deep into the skin. Fast absorbing and free of parabens, ethanol, parabens, artificial color, artificial flavor, triethanolamine, and phthalate.

Our insight:

What exactly is galactomyces and why is it so good for your skin?

It’s a long, geeky name for a type of fermented yeast packed with vitamins, amino acids, and enzymes. The fermentation process breaks down its components so they penetrate into skin more effectively, making for a stronger shield against free radical and UV damage, a major cause of premature aging.

This is such a good option for a toner! I highly recommend it, especially if you have sensitive skin or if you're just starting off. It is packed with great, fermented ingredients that will keep your skin hydrated and ensure their effect is delivered deep into the skin.


Definitely good for a refresher throughout the day! You can use it as a toner or spray it after applying makeup and because it doesn't have any alcohol, it won't dry out or irritate the skin.


I love this formula, adds a good bit of hydration and leaves my skin plump and glowy all day! Also the added UV protection helps with my hyperpigmentation.


It's the summer time and I must say that this formulation works wonders on my oily skin. On top of it being extremely affordable (winning!) it also doubles as a face mist, which you can carry around with you when you feel your skin needs a quick boost without looking dipped in oil. Safe for darker skintones as well!


I love Cosrx products, feels hydrating and smoothing, work wonders on oily skin , it is wallet friendly, good formulation, and if you love dupes as much as me this one is a Dupe of the SKII which is insanely expensive.


I like this toner a lot. I suffer from acne and I have combination skin. Ever since I incorporated this to my skin care routine my skin looks very healthy and my acne is under control.
