When mixed with distilled water (skin serum) and stored in a dark bottle, does this need to be refrigerated in order to maintain the C's stability?

Vitamin C breaks down from oxygen not temperature. Therefore, each day after being mixed, it loses some potency!

If the bottle is kept closed and away from direct light, it seems to retain its potency for quite a while. I often add generous amounts to face and body cream, so I've never had a bottle of it for more than a few months. I do not refrigerate it and it always stays as strong as when I first opened it. If your pores are open from exercise or a hot shower, you will definitely feel it working. Also, if you use it right after alpha-hydroxy products, you may feel a slight sting. Overall, its a good way to add Vit C to your cosmetics and I prefer it to the liquid versions. Good luck!

I have never stored it in the refrigerator. I use it every day on my face, hands, elbows, feet and leave it on my dresser...After 2 months I needed to order more and happily did so. I'm sure the vendor would have a better answer for this. My memory is it isn't necessary. I also have had no breakouts on my face and use it exclusively as my moisturizer morning and night. The expiration date is 6 months or more after I purchased so it will be gone way before I get to it!!

My bottle does not say it should be refrigerated after it's opened. Perhaps the other responder was referring to another brand? I found this brand to be far superior to powders, particularly those that mix in artificial sweeteners.

NO! Refrigeration will also add moisture which will deteriorate the capsules.

Yes, it does keep well. There is a "best by date" on the bottom of bottle. I do not refrigerate the product, and have never found it to go bad.

No, does not need to be refrigerated. Bottle says to "keep it in a cool, dry place"

The bottle does not mention refrigeration, but we keep it in the refrigerator after opening it just to be safe.

I do keep it refrigerated, and don't order if its going to be hot, you may loose some of the effectiveness or possibly ruin it completely. Great product IMHO

I keep my open bottle in the refrigator. I cannot prove it but i believe heat is not good for this liquid product.

It needs to be stored in a cool, dark place- the Vit. C is light sensitive. I put it in my medicine cabinet and that seems fine.

Refrigeration is only needed after opening this product to maintain its high potency. However, this product is not shipped refrigerated. Thank You,Customer Service I saw this answer to a customer's question. Where does it say that on the bottle that refrigeration is only needed after opening product?

The instructions on the box say "Store at room temperature. Do not expose to excessive heat, humidity, or direct sunlight."I keep the bottle in the box it came in, to reduce light exposer.

Other answers to this question say that the package says to refrigerate after opening. I do not have the bottle in front of me to verify, but I always refrigerate it myself.

Yes, this product needs to be refrigerated. Says so right on the bottle " Keep Refrigerated". If you purchase this product on Amazon and the listing says "Fulfilled by Amazon" it has not been refrigerated. It was kept in and shipped from Amazon's warehouse. The response from Green Pharmacy is incorrect as are the instructions on the Empirical Labs website that say "refrigerate after opening" according to Dave at Emperical labs. According to Dave, he has asked his web people to change the wording on the web site and that takes time but he has put the necessary paper work in to have it changed.

I did refrigerate the actual bottle. However, I used it to make hand sanitizer and did not refrigerate the hand sanitizer.

No, it does not. And it does not need to be refrigerated after you receive it. If you were to buy it in a store, it would be on a shelf in an aisle that is refrigerated. It does need to be prepared in a cool drink though.
