Nasha Grade Hyaluronic Acid Serum
Can someone please help me in the formulation of a Hyaluronic Acid Serum to sell as a new business. I want to offer the best serum to use under a luxurious hydrating face cream. I need to know what I add to keep the serum from “going off” so I guess I need to know what the preservative should be and at what percentage. The next question would be is how many more actives could I add to this serum and at what percentages and then if I add actives would I then need to add anything other than the preservative? I want the product to really work and for my customers to really see a difference and I believe this serum will do that. I look forward to hearing any feedback on this serum and I welcome any input.
