INCI: Ganoderma Amboinense (Mushroom)/Apple Ferment Extract Filtrate
A gentle fermented blend that may help soothe and protect the skin, but research is still emerging.
In plain English
This ingredient is made by fermenting reishi mushroom and apple together. Fermentation breaks down the plant materials into smaller, potentially more skin-friendly compounds. It's thought to provide antioxidant protection and support the skin's natural barrier, but most evidence comes from lab studies rather than human trials.
