First, let me formally introduce you to the serum. This stuff is no joke, and it's an industry favorite for a reason. Not only is the patented formula backed by 15

years of scientific research, but it's made with quality ingredients, such as bifidus prebiotic, vitamin C, and hyaluronic acid, which help to visibly smooth, hydrate, and refine skin texture. The formula also speeds up skin-barrier recovery (a strong skin barrier is the key to maintaining youthful, healthy skin—remember that!) and helps defend against external aggressors like pollution, and cold and dry weather. It's widely known as the go-to serum for skin that looks smoother, softer, and more even, with visibly improved radiance in one week and reduced appearance of fine lines and wrinkles after one bottle. The best part? In just one drop, it makes your skin barrier stronger.
