Glutone 2% Hyaluronic Acid Serum contains 10 molecular weights (from 300Da to 23,00,000Da) of HA, which helps to penetrate different layers of the skin. The hydrolyzed HA (the smallest one) moves deep, stimulating collagen production, whereas the mid-molecular weights help to stimulate epidermal differentiation. High molecular weights remain in the higher layers and keep the skin hydrated and supple. It is enriched with vegan collagen peptides, which further improve the water-holding capacity of the skin.
