Does it expire? Is there a date on bottle?

No date, it only goes bad once it's exposed to oxygen. Once it's out of the bottle , it starts oxidizing ...hince why you must wait 72 hours to wash.

There is no expiry date on this product, it seems that it would last for a long time.

The bottle doesn't have a date. I have kept the keratin over a year but I have only ordered the 8oz bottle witch will last me about 18 months and I have long hair.

No date ~ I would not buy this product without using a credit card. I received a knock off product and they won't take returns. I went ahead and used it and it didn't last a month.

There is no expiration date on the bottle, but I have been told by a hairdresser friend of mine that it does have a shelf life of about 6 months after opened.

Yes there is a date in the bottle. From the time you open the bottle you should use it within a year. It's been great to have a good friend do it for me. I had it done in the salon 4 times at 300.00 each time. I give my friend a little something and she does a great job. Be sure to have the recommended flat iron.

I have had mine for over a year and it is still perfectly usable and works. I don't get sick with taking this stuff. I don't know of any expiration date on my bottle.

I do not see an expiration date on the bottle; I go through this stuff in about a month, so I would not need to worry about it. Are you planning on not using it for over a year?

There is a code stamped on the bottle, but no expiration date. It was sealed, and seems fine. I regret I do not know the expiration date.

There is no expiration date on the bottle. It only says refrigerate after opening and use within 30 days. I hope this will be helpful.

Mine has expiration dates stamped on the bottom of the bottle. When I purchased mine it had a little under a year until it expired. Hope this helps.

Yes there is an expiration date on the bottle. I don't store in the refrigerator. It is rather expensive so I buy one bottle at a time. Hope this helps!

Hello. No expiration date on bottle and it won't damage. I am medium dark skinned. It really works to get a dark tan for me. No issues

Bought mine in August/2014 and expires in August/2015. Even though its just a year the bottle only lasts for 300 days anyway!

Not that I know of. The bottle should last about 6-8p months. I would discard after that. The serum gets brown with time, but that is not an indication that it's expired. Perhaps skinceuticals.com could help further.

My product expires 12/15. The dates are on the bottom of the bottles. Hope it helps...

My guess is it's old, expired product. The new packaging has been around for a while. Does the bottle have an expiration date?

I looked on my bottle and it has no expiration date. I didn't save the box. Sorry I can't be more help.

I can confirm the previous comment, there is no expiration on the bottle. I have had a few bottles I stockpiled and used them a few years later. I am not eating it, so I am not too concerned...still smells the same and my skins still feels soft and healthy.

Funny you ask - I can not find an expiration date anywhere on this bottle - sorry - I don't know what to say. It's a mystery.

The expiration date is on the bottom of the plastic bottle. I purchased mine several months ago and it expires in April of 2014. It's great stuff!!
