Hyaluronic Acid is, deservedly, an iconic ingredient in skincare formulations.  It can hold up to 1000 times its weight in water.  Moreover it is a humectant. That means it absorbs moisture from its environment. It hydrates, plumps and evens skin tone.  And because Salubre's Hyaluronic Acid Serum is made with both low-to-medium molecular weight and high-molecular weight botanical hayluronic acid powders, it is great for aging skin and acne-prone skin alike.  And, as is the case with all Salubre products, our Hyaluronic Acid Serum does not contain artificial perservatives.
