Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.

Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.

In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.

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.

Parfum is a catch-all term for an ingredient or more that is used to give aroma to products. Parfum, or fragrance, can be a blend of hundreds of chemicals or plant oils. This means every product with "fragrance" or "Parfum" in the ingredients list is a different mixture.

In the US, the alternative name for parfum is 'fragrance'. The term 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.

For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance. One example is Calendula flower extract. Essential oil ingredients still impart a scent or 'fragrance'.

Depending on the blend, it can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.

Products use parfum often to give products a scent or cover up smells of different ingredients.

The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.
