With every natural-foods devotee singing the praises of fermented foods for a healthy gut and body, it was only a matter of time before the trend jumped from the pickle jar into your night cream. And that’s not just a fad gone wild—according to a study published in the Journal of Medicinal Food, the active compounds in fermented red ginseng may fight wrinkles better than those in unfermented red ginseng, giving you smoother skin with minimal irritation.
