I called company: products do not expire. Wouldn't give exact amt due to proprietary formula, but did say all products are &lt; 12% Hydrogen peroxide

I have chemistry background. Hydrogen Peroxide degrades to water when exposed to air. Once you open a product with hydrogen peroxide in it the clock starts. I was taught that once you open a medication such as this, use it up in the next few months then toss. I used one that was in my cabinet for several years. Got no response. Trashed it. I order new one and starting with it freshly opened got a response. However, after using the product twice a day for 15 minutes for two weeks, I was disappointed at the very very small change in shading. I expected more dramatic whitening. Good Luck!

I found an expiration date on the bottom of the box. Look for "Exp." followed by the date. On another note, they are not making this product any more.

This is how it's listed:NON-BLEACH- active ingredient: hydrogen peroxide 1.4%Other ingredients:98.6%Total:100.0%That's all it says! Doesn't list the "other ingredients".... Weird it doesn't list what the other inactive ingredients are? But it does say for MSDS info go to www.cloroxhealthcare.comAnd here's a phone number for questions or comments: 1-800-234-7700

Unfortunately, NO I cannot find an answer to this. I emailed the company over the weekend, however, they didn't get back to me about the expiration date. Sorry. S A Little

The product doesn't have an expiration date on the bottle so, I would suggest you contact skin obsessions to verify expiration.

I'm sorry I'm already on my second tube and threw out the boxes. I'm sure Amazon wouldn't sell it if it's expiring and if they do then you email them telling them is faulty and they'll pay to ship it back. I hope this helps! Debby

I think only the seller can tell you that. I've never had any problem using this type of product way past its expiration date. The expiration date is probably pretty arbitrary. (If this product was totally organic, that might be another story.) It's not as if the product is good one day and bad the next. I love this moisturizer, and I'm about to introduce my daughter to it, now that she is 31.

I did not see an expiration. But the active ingredient is peroxide based. Hydrogen peroxide degrades to water when exposed to air. So as long as the cap in on the syringe it should expire. If it does it will either dry out or become water.

Another seller mentioned 06/2016 or later but I can't no for 100 percent since amazon have the product and I do not. Amazon policy is to not sell anything that expires within 90 days. Also remember, vitamins never really expire. The only reason why the expiration date is there is to sell more products. However, 2 or 3 years past there expiration date they may lose a little of their potency. But it is not measureable. If you give 1 gummie a day with this bottle you will be finished in 275 days. 100 percent safe in range. and please keep in mind, its not a safety concern anyhow. Simply a minor potency loss. And that would take 3 to 4 years minimum to even be able to measure in a lab. Another seller mentioned 06/2016 or later but I can't no for 100 percent since amazon have the product and I do not.

I don't remember looking for/or wondering about an expiration date; my product never had a chance to expire, I used it all up!

The seller I purchased from sold me one without an expiration date. I discontinued using it after I learned that it didn't have a date on mine. Also, I believe its active ingredients were affected by this, and thus did not work properly on my skin. Having not purchased this product again by any other seller, I do not know what timeline is normal. But please read the comments under my review, they might help also.

My bottle sadly has been diluted to 8% (says so right on the label). Another case of false advertising. This is the second time I have ordered 35% H202 and it arrives diluted... but originally it really was %35 !!!??? I think it might be illegal to deliver @ 35% peroxide because it is classified as a hazardous material. I'll keep searching...

I hope I am not too late in ansering your questions. I had several exepeinces. The very. I got some with only a few months to expiration, and some for over a year. You may want to ask the seller before purchase.

We have not ever had trouble with this product going bad, we do use it everyday though. You may want to ask the maker of the product for detailed info about what they would recommend for expiration.

Maybe Google the name brand and see if an expiration date will be listed. Or e-mail the seller, I am sure they would be more than willing to help. Good luck

The short answer is yes, but I have have successfully used this product well past the expiration date with good results.
