Galactomyces Ferment Filtrate

What it does: Humectant

Community Rating: Liked

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 applied to the skin 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.

GFF 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 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.

Niacinamide

What it does: Smoothing

Community Rating: Loved

Niacinamide has emerged as an all-star ingredient due to its many benefits.

It is known to treat acne by reducing inflammation. It also helps fade dark-spots and strengthen the skin by promoting the growth of the ceramide barrier.

Other benefits include smoothing wrinkles and minimizing redness.

The cherry on top? Niacinamide can also help build keratin, a protein that keeps skin firm.

When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.

Niacinamide can be mixed with other ingredients to boost benefits. For instance, it has shown to be effective when used with copper, folic acid, and zinc to treat acne.
