I used this a while back and switched to a different essence for a while. My skin started being less glowy, hydrated, plump, everything you want your skin to be. After switching back, my skin has regained all of those qualities. I. mainly. attribute this to all. the powerful fermented ingredients. Plus, the niacinamide is so great for quickly fading any acne scars, which became big concern of mine while not using this product.
