Science tells us we should eat fermented foods. Not only are they delicious (hello, kimchi!), but they're full of easily digestible nutrients like probiotics, fiber, and fatty acids. Through fermentation, food is broken down, making it easier for its nutrients to be absorbed by the body—and the same holds true when those nutrients are found in fermented beauty products.
"When different seeds are fermented, the oils that result are thinner and can be absorbed better," explains Janice King, director of marketing at Goodal, a beauty line that boasts fermented elements in all of its products. "Because fermentation is a metabolic process that breaks down components, it also results in a milder product, which can be gentler on skin."
When they can be absorbed more quickly and thoroughly, products become more effective, so consider your skincare routine turbocharged. Fermented products have some additional bonuses, too. Amino acids and enzymes produced by fermentation can increase cell regeneration, hydration, and skin elasticity—which all fight the aging process. To sum it up: a little fermentation can do a lot of good.
