Hyaluronic Acid Serum losing viscosity
Recently i made 2 serums
1 with Sodium Ascrobyl phosphate
And 2nd with Niacinamide
Both have Ha at1%I’ve noticed that serum with SAP lose its viscosity in a day or two it becomes thin in a day or two
Recently a bottle of Niacinamide serum was used about a quarter and put aside after like 5 days that setum is also very thin
While the other bottle from same batch which was not opened is still quite thick
What could be the possible reason of Loss of viscosity
