BeautyBio The Daily Intensive Vitamin C Serum is a proprietary daily serum that helps to moisturize skin, fight against free radical aggressors, and has photoprotective qualities helping skin appear smoother, younger, and more even. It is also shown to help increase collagen production and help skin maintain moisture retention. This fast absorbing formula contains HyperVitamin compound, uva-ursi extract, yarrow flowering plant extract, and other key ingredients. Unlike many serums in the marketplace, this serum features magnesium ascorbyl phosphate (a component of hypervitamin complex) which is a stable precursor of vitamin C. Fast absorbing and designed to work both independently and layered under other treatment creams each morning, the serum's airless pump helps keep active ingredients at peak concentration. How do I use it: Apply one to two pumps of facial serum evenly to cleansed face once a day in the morning. Individual results may vary. From BeautyBio. Includes:
