Dermatologists claim that this is the best ingredient for achieving "glass skin," and it’s likely that you haven’t heard of it before.

      There are numerous multitasking skincare ingredients available today, such as retinol, niacinamide, and vitamin C—all of which are effective on their own. However, a few select ingredients are particularly favored by editors and experts for achieving "glass skin," a trend that began in South Korea and emphasizes smooth, plump, and ultra-shiny skin. One of these key ingredients is snail mucin, which I highly recommend trying if you haven't already. Another notable ingredient is galactomyces. Although it may sound like something from a science fiction narrative, it is actually a widely-used Korean skincare component known for its significant effects on achieving glass skin. Read on to discover more about this potent ingredient that is gradually making its way to the United States, and check out the top galactomyces-infused skincare products recommended by dermatologists.

      What is galactomyces? Dr. Brendan Camp, a double board-certified dermatologist at MDCS Dermatology in New York, explains that galactomyces is a type of yeast. "The suffix '-myces' indicates a fungus," he notes. "It's found in fermented products like rice wine (sake)," he adds. "Fermentation involves the yeast transforming carbohydrates or sugars into simpler substances like alcohol or acids." Dr. Noah Gratch, another board-certified dermatologist at MDCS Dermatology, mentions that galactomyces is typically incorporated into skincare formulations after fermentation, becoming a nutrient-rich yeast by-product. "When referred to in skincare, it's often labeled as galactomyces ferment filtrate, or GFF," he explains.

      How does it benefit the skin? Similar to other fermented skincare ingredients, dermatologists assert that GFF has multiple benefits for the skin. "GFF is mainly used in skincare due to its capacity to reduce discoloration by lowering melanin (pigment) production. It's also a robust source of antioxidants that shield the skin from free oxygen radicals, which are unstable oxygen molecules that contribute to fine lines, wrinkles, and dark spots," says Camp, who also mentions its hydrating properties for a youthful, plump look. Gratch concurs, stating, "Galactomyces is valued for its hydrating and brightening antioxidant qualities. It's suitable for all skin types, as it helps retain moisture for dry skin and can balance sebum production for oily skin. Its antioxidant benefits are also advantageous for dull or aging skin, enhancing brightness and elasticity." In summary, GFF addresses issues like dryness, dullness, hyperpigmentation, signs of aging, and excess oil, making it a crucial component of "glass skin" skincare products and routines.

      Are there any downsides? While GFF is generally well-tolerated by most skin types, both dermatologists advise caution in certain situations. Camp suggests performing a patch test regardless, especially if you have sensitive skin or conditions like rosacea and eczema. Gratch advises against using it if you are prone to fungal acne, since "yeast is a fungus that may exacerbate" this type of acne. For optimal use, most GFF-containing skincare products support daily application for best results. However, exceptions may exist, which is why Camp recommends checking the specific product instructions to determine the appropriate frequency of use.
