How long will the product stay effective after the bottle has been opened?

I am not sure how long the product will remain effective but I use a fresh supply at beginning of season and it works well until September. If going to Caribbean I suggest 100% DEET only and fresh supply. Dengue and Chikungunya too dangerous to risk any bites.

It usually lasts about 4-6 days. If you apply it every 5 days you should be good.

Cesar M., how long it lasts depends on the size of the area that you're trying to cover as well as the frequency of use. I've actually been using the same bottle for a few months now. I definitely recommend it though.

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.

Sorry I can't answer this question, I don't have the bottle any more. It is a powder so I'm guessing it should last a long time.

I've had the same bottle opening for 3-4 months and it's been fine. Not sure about 10 years. Ask the manufacturer.

Because of the cool way the bottle works this product can last quite a while. 20 to 30 days, easily.

For me the effects last 4 to 6 hours depending on activity factors. Unless you over-apply there shouldn't be any visible residue to flake off.

It shouldn't has any problem, my personally use the same bottle for more than 6 months now, and it is still working fine and effectiveness.

Over a year on the use by date on the bottle, I refrigerate it after opening it and generally use it within 6 to 8 months. Always stays fresh and the taste is always the same.

I was given my first bottle by my sister, and I haven't had to purchase another one yet, so I do not know the average shelf life of the product. Sorry! I'm sure the manufacturer would be able to provide this information.

The longer it's in your water the safer it is. 30 minutes is the recommended time and on the bottle there should be a peel hear label where you can find more information. I would also suggest using them up in a weak because the Iodine tablets will start to decompose after opening.

Like the other poster said, my bottle was in the fridge for at least a year before I started using it, and I had already opened it. It was fine. So long as you keep it refrigerated it will last a very long time. I am guessing the acidity level and the fact that it is concentrated, is what helps keep this fresh.

most eye drops that require refrigeration are good for 30 to 45 days after opening

Simple. Use the complete bottle. If it is not effective for you - simply return the empty bottle after 30 days. You will get a 100% refund - including shipping and handling.

See back label: There is a drawing of an open jar with "24M" written in it. Clubman therefore recommends you discard the product 2 years after opening the bottle. I suppose that is only a suggestion :)

Yes, it says right on the bottle, "For best results, refrigerate after opening." I have always followed that advice.
