I know with some bleaching products, they last longer when kept in the fridge. Is that the case with Ageless?

I have used this product for years and never put in fridge. Hope this helps?

I've never tried that so I don't know if it works. Ageless is the only one of the 3 products I tried that lightened the dark spot on my cheek.

The Synergy Company's peerless supplements & fruit/veg powders have a good long shelf life packaged in best light-protective & preserving dark glass vacuum sealed instead of less effective & toxic plastic. They told me the fruit/veg powders last several years kept cool & dry out of direct sunlight. Surprisingly my bottle has no expiration date stamped on it, but we use it up sooner than 2 years. If I found some old in the house, we'd still consume it knowing potency maybe reduced but since Vitamin C natural preservative I bet would take a really long time if ever to look/smell spoiled--likely over time just dessicate dry like potpourri.

i put it in the fridge as it says on the instruction label. you just have to follow it for the best result. for me, i believe the serum can last at least 6 months. but for sure, please contact the seller that would be helpful for you.

I'm not sure if the date was on the package or stamped on the sryinge itself. I do know my dentist told me the shelf life is longer if you store it in the fridge. Between my wife and I we used it up before the date, so it wasn't a problem.

This brand stores the oil in amber bottles, which gives the oil longer shelf life. If you keep the oil in the glass bottle in a cool dark area (bathroom cabinet) it will last 6 months-two years. It all depends on how its kept. But I personally love this brand!!

My husband says he had always had several different Meguiar's products; Waxes, Cleaners, etc. If the products are kept tightly closed and in a dark cabinet, and not subject to extreme temperatures, will they last years. He had some partial bottles more than 5 years old and they are still good. I read they do not freeze well, so if storing in a garage it may be a different story. We have ours inside in a cabinet.

HA does have a shelf life yet that life seems to be at present neither quantified nor common knowledge. I find that my bottle seems as potent and clear as when I first opened it months ago. I usually store all serums in the crisper drawer in my fridge, though instructions most often merely specify to store them away from direct heat or sunlight. I can say that this product is absolutely amazing -- and is perfect for under makeup (which I have rarely tested as makeup is something I dabble in perhaps 2-3 times a year) as it fully hydrates and then dries quickly and completely. I use this, DIY vitamin C serum (so easy, and with a very short shelf life in contrast to its unmatched efficacy), and a copper peptide to rather surprising results! My skin looks better at 51 than it did at 31. I hope this helps.

I am not sure of your question however, I keep it in the refrigerator. it soothes my eyes better. I have not reached the expiration date yet. Anything kept in the refrigerator lasts a little longer. I hope this helps with your question.

Bleached is better over time. Sooner or later the bleach teeth will darken and look norma . I order bleach all the time. I tried normal did not like it. Normal color got darker to soon. Cheer.

I don't remember if there is an expiration but I am sure there is one. On the bottle it says it may turn to another color once opened. I will tell you this, for someone with discoloration on my face (cheeks mostly) it didn't help me one bit!

I keep mine in the frig. I think it will last a long time. It's mostly peroxide.

Same here. I used some at Christmas, and refrigerated the remaining container. Still fine. Based on similar products, as long as you keep it sealed and refrigerated after opening, it will last many months

Generally, the expiration dates are provided as guidance for optimal quality. Much of the shelf life depends on storage conditions. The cooler and drier the ambient conditions the product is stored in for a powder product like BiPro the longer the shelf life. Being exposed to direct sunlight and the lid being loose will shorten the shelf life. Many foods that contain vitamins fortifications lose potency over time but BiPro does not contain fortification nor flavoring so this mode of aging is not an issue. BiPro, being unflavored, can pick up aromas from things around it so again keep the lid secure and stored in a cool dry place. All that being said, the shelf life specified for a powdered protein like BiPro is generally two years from date of manufacture. If conditions of storage are cool/dry/dark in an intact container with securely fastened lid, the product should remain nutritious and clean-tasting well beyond that...but once a product is in your home so much is out of a manufacturer's control that a shelf-life with a reasonable duration must be used as a safe compromise. The longer the product sits in your home past the expiration date the greater the chance you'll be unhappy with the taste.

NO. It is not necessary to keep in fridge. Keep in a cool dry & dark area like a cabinet. It has a long shelf life and primarily light or exposure is the only things to affect it. There is no expiration date as it can only become less efficient over time similar to peroxide.

The seller gives you their latest batch and I remember I did not have any issues as far as the expiration dates are concerned. But just to give you the heads up, the yellow which was rated by the manufacturer as their brightest product, is not that REALLY bright. The green ones are far better IMHO.

I like the 14% Day White better than the Night White, because I don't like sleeping with bleaching trays in my mouth. I get good whitening from the Day White formula. I use it twice a day and leave it on my teeth for 30 minutes, each time.

I haven't ever refrigerated mine and get great results. To be honest, Rainbow light products are some of the first vitamins that I can feel the results with-fantastic stuff!!
