Perfect for all skin types, this DIY hyaluronic acid serum hydrates and nourishes skin. We make less hyaluronic acid as we grow older, which is why topical application makes such an impact.
Pour in distilled water and glycerin or leucidal if using.
Place a lid on the jar and shake well. It will look very chunky at this point, but don’t worry. As the hyaluronic acid absorbs the water the consistency will become more smooth.
Place in the fridge for several hours (or overnight) to allow it to thicken before use.
Notes
Shelf life: Without a preservative I store my serum in the fridge and use within two weeks. With a preservative it can be stored at room temperature for up to three months.
