Originally a Korean beauty trend, fermented skin care can reduce the signs of aging while treating skin gently. Just as yogurt, kimchi, and kombucha promote healthy gut bacteria, fermented fruit, plants, and tea in skincare products can promote a healthy skin biome. Harnessing the power of fermentation also replaces traditional preservatives and increases the shelf life of beauty products.
Did You Know?
Fermented ingredients can increase the shelf life of beauty products without the use of chemical preservatives.
“Fermented ingredients can increase hydration and boost the performance of the actives by breaking their molecule size down, helping them to absorb better,” says Holly Harding, INHC, AADP, creator of O’o Hawaii skincare products, which feature fermented radish root. “Fermented ingredients also preserve the product, and help crowd out bad bacteria that can cause dull or acne-ridden skin.”
In addition to creating antimicrobial organisms, fermentation produces antioxidants, peptides, and amino acids that hydrate, increase antiwrinkle collagen synthesis, reduce inflammation, strengthen the skin barrier, and help maintain normal skin pH. Popular fermented ingredients include apples, berries, pumpkin, radish root, seaweed, black tea, and yeast.
“Radish root is fermented with the microorganism Leuconostoc, a bacteria from lactic acid,” says Harding. “Small amounts are used in skincare products to protect them from harmful substances that can contaminate the product.”
As the trend of fermented beauty products catches on, look for scientists to discover even more benefits from fermenting different ingredients.
