Ingredient Breakdown: Fermented Yeast

Share Tweet Pin

By now, most skincare fanatics know that miracle, fix-it-all ingredients don't really exist. In fact, science shows that a beauty routine that incorporates several high-powered ingredients is the best way to combat signs of aging, skin damage, and all those other fun things we deal with on a daily basis. But, how do you know which ingredients are worth the hype? We're making it easy! Welcome to our new series: Ingredient Breakdown. In this series, we'll give you the must-know info on both trending and mainstay ingredients. Today we're spotlighting fermented yeast.

We first noticed fermented ingredients when they began popping up on our favorite Korean beauty sites. The benefits of eating fermented foods (think Kimchi and Sauerkraut) have been well documented; they promote a healthy gut and improve digestion. As it turns out, fermented plants and other popular beauty ingredients also have topical benefits. 

The Ingredient: Fermented Yeast (and other fermented ingredients)

Also known as: Fermented yeast is pretty straightforward but other popular products used in fermented beauty include algae, kombucha (black tea), and fruit extracts

Quick take: Fermented yeast helps break down the enzymes and nutrients in a product and make them ultra effective by concentrating their skin-altering properties.

Claims to fame: Fermenting is a natural preserving process. It increases the nutritional value of foods by boosting the effectiveness of the acids and enzymes they contain. Fermenting the plants and ingredients we put into skincare products concentrates them and makes them more potent.

Where to find it:
