I make my own Vitamin C & Hyralonic acid serum. I use ascorbic acid. I keep it in the frig (life=2-3 weeks). Never experienced your problem. I give to family/ friends. I do use small amount of (1-2%) of Leucidal Liquid SF, & amber bottles. Been making it for about 3-4 years. I do feel it is effective, as there have been periods when I did not use it.
