When you hear the word fermented - you don't typically associate it with your beauty routine. But Immunocologie is the first brand to use a unique patented process called Bioferm, that actually ferments the ingredients over time. This process prevents oxidation, allowing the products to maintain maximum potency and effectiveness. (This is opposed to cosmetics that are just blended together, and then heated.)
Immunocologie has a full line of products (Serums, masks, cleansers, creams) that intend to lighten brown spots and improve skin tone and texture. I tested out the Immunocologie treatment cleanser and noticed that my face instantly felt much softer and smoother. I guess cosmetics, much like beverages, are often better (and stronger) when fermented!
