Lactobacillus Rye Ferment This ingredient is made by fermentation of rye. During this process unique beta-glucans are formed that support a better immune system. That also prevents the problem causing bacteria, responsible for the occurrence of zits and blackheads, from multiplying excessively. Besides that they speed up the healing process of a blemished skin. They’re useful in alleviating the irritation, minimising redness and they help to impair scars and spots.
