Pre-made hyaluronic acid solution. Our body naturally produces hyaluronic acid, primarily in the joints and ligaments. In youth, its levels are abundant, but as we age, production gradually declines. High Molecular Weight (HMW) Hyaluronic Acid is derived from hyaluronate salt and is commonly produced through bacterial fermentation. Known for its exceptional ability to retain moisture, hyaluronic acid helps hydrate and plump the skin, enhances elasticity, and provides a protective barrier against environmental stressors. This makes it a key ingredient in many moisturizing and anti-aging products. According to studies, hyaluronic acid at 1%, and with high molecular weight is the safest combination for skin for protection of the moisture barrier. Water-soluble. Add into the water phase of your formulation, or use as standalone hyaluronic acid serum.
