Simple DIY hyaluronic acid serum recipe. Preservative-free. An affordable alternative to pre-bottled versions of this healing and moisturizing anti-aging serum. It only takes mere seconds to prepare the serum.
*The brand I suggested above comes with a 1/8 tsp scoop right in the bag
**Unless you add a preservative the serum will need to be refrigerated. It should last a couple weeks there without issue.
