A Lactobacillus extract balances the microbiome by creating an environment on the skin that supports the presence of beneficial species. Inulin and Alpha-Glucan Oligosaccharides are prebiotics included to selectively feed beneficial microbes in order for them to outcompete invading species common in sensitive skins. Formulated to proactively calm and protect reactive skin to enable even the most sensitive users to address the signs of ageing.
