What is the expiration date of this

If it turns yellow it most definitely *is* oxidized and shouldn't be used. There is no benefit to oxidized vitamin C and I'd even guess that it could have the opposite of the intended effect. I personally stay far away from oxidized vitamins. That said, I don't see how a formula of plain ascorbic acid and water could be stable. It's a perfect recipe for fast oxidation.

I believe it's stable even when it oxygenates and turns a darker yellow. I have been using Cellex-C products for over 20 years. First introduced to the "Serum" by Plastic Surgeon's practice then switched to the cream about 3 years ago. Neither seems to lose efficacy over time so I'm not sure they do "expire".

Keep it refrigerated; it will last for months. I only use a small amount on specific "spots".

I didn't see the expiration date so I am not sure if this product has an expiration date or not. You can always ask the seller before you order it.

I am not selling this product. I have purchased it before and was very pleased with it. Am unaware of any expiration date though. Sorry i am not more helpful :(

The order I received recently has an expiration date of July 2016. Because I use it almost daily, I'll use mine up way before it expires.

There is no expiration date on the package...I looked at both sides and there is nothing there regarding expiration dates.

It comes in a package and I am not sure what the expiration date is. But if you use it everyday you will not need to worry about it.

It says Lot 1 10/04/14 so I would guess that's the expiration date. I bought this about 4 months ago. Best stuff ever.

The expiration date would be on the packaging. There is no possible way anyone who bought the product on Amazon would know what the expiration date is for the product you bought.

You can find the date at the bottom near the barcode. It doesn't expire for me till 2019 and bought this 6 pack couple months ago.

The expiration date is on the box, not the jar. On my previous purchase, the date was on the bottom of the box and read 06/14. The expiration date on the new jar I purchased is on the side of the box and reads 1/2015.

There is an expiration date on the package. I wouldn't use it after that date.

I checked the bottle and couldn't find an expiration date. Maybe one was written on the box but I no longer have it. Sorry I couldn't be more helpful.

I have never looked at the expiration date. I have never had any issue of any kind. I still use the product. I always use it in a sterile environment.

Don't see an expiration date on it. We always use ours up really fast so I've never thought about that.
