Good news! (at least for PSF customers)
This is the response I got from their chemist:
"All of our products undergo product failure testing, which includes
cycles of freezing & rethawing and exposure to conditions of extreme heat. The actives in the Berry Beneficial Antioxidant Serum appear to be stable
up to 172*F, which is certainly well above how warm they would become in
normal shipping during the summer months."

| Good to know that at least PSF has been tested to remain stable in temperature extremes. For other types of Vit. C serum, is it practical to order enough to last for 1 year so you don't have to worry about exposing your order to temperature extremes like heat/cold, or would the actives expire by a given amount of time? |
I don't think there would be too many Vit C products designed to last 12 months. Depending on where you purchase it from, it may already have been sitting around on the shelf for quite some time. I have always found the stock from EDS to be fresh. So it probably would be better for you to use the product soon after receiving it. |
