Using a small funnel, pour the water into your dropper bottle. Add the hyaluronic acid powder, then screw on the lid and shake vigorously to dissolve. The cold water should help the powder dissolve more easily, but if you’re still seeing chunks, you can put the mixture in a small blender or food processor to get it to mix completely.
Add the glycerin, carrot seed oil and neroli oil. Replace the lid and shake again.
Let the serum sit for at least 4 hours to allow the hyaluronic acid powder to dissolve completely before using.
To use, apply a bit of serum to freshly washed skin and let it soak in. Follow up with any additional serums or creams. Apply 1-2 times a day to keep skin looking fresh and dewy.
Store remaining serum in the refrigerator for up to 2 weeks.
To keep your serum fresh, feel free to halve the recipe to make smaller portions. And while the supplies can be a little pricey upfront, they're used in such small quantities that they should last for a long time.
