HA4C is an ultra-lightweight serum that contains Hyaluronic Acid complex, with an ultra-low molecular weight that is 60 times more soluble than standard Hyaluronic Acid. This provides quicker penetration through the layers of the skin for faster moisturisation 🙌🏻 After twice daily application of HA4C, there is a significant improvement in hydration across all facial areas 👏🏻 HA4C contains the optimal concentration of glycerin to prevent trans-epidermal water loss and establish a normal moisture balance for a more hydrated, even skin surface.
