Does this lose its potency after opened? I used it once and it worked and the next months it didn't

The answer is I don't know. I tried this product and had a SERIOUS reaction to it. My eyes swelled up so much ans hurt badly.

Hi, I had no problem..its still workung great..but I always close very good every little bottle..perhaps you didnt close it or perhaps it was to expired? sometimes it happens with beauty products however as I said it is still working for me..

ive had mine for a few months now. i just used it again about a week ago and it worked just fine. bit i keep mine stored the same way the bottles came with that little plastic cap then the regular cap over and tighten it a bit. i think the key is making sure the cap is on tight so no air can ruin the liquid.

The first three times I used it it was perfect. Now, not so much . I'm due again and I plan to open a NEW bottle of the perm solution, the first part. I know what you mean but I'm not sure if it actually loses potency.

I am not sure I can answer your question, but I can tell you that I've used it a few times and it seems to work just fine. Hope that helps.

The first time I use it about two bottles and it worked perfectly fine. Afterwards I bought two more bottles in the shelf life and to be quite short. Again I bought .two more bottles and the shelflife seem to be very short. It turns a very creamy Orange Color. It was somewhat disgusting. I think the shelflife is only 30 days I never buy more than one bottle or time

Mine stayed potent for several months after I'd opened it - I kept it in the fridge and it was as good the last day as it was the first

I use a bottle every 4 months or so. It turns color to clear but I haven't noticed any change in performance.

my experience has been one hour minimum and up to 3 hours or so. It loses effectiveness after about 3 hours anyway per their instructions.

Indefinite...I bought mine well over a year ago and I would imagine it will still be something I'll have in my spice cabinet for another few years or so, at least. It's a powder like any other spice and should last until you use it up!!! I think the other answers are ok but, I know it will last more than 1 year from experience!

Hi Joseph, yes there is a shelf life to this product. I bought the product in February of 2012 and the bottle I bought is dated best by 7/20/13. So the product appears to have a one year shelf life. However this still does not indicate that you can't use it after the year. I interrupt this to mean that it probably will then start to losing its potency. I hope this helps.

Read the expiration date stamped on the bottom of the package and on the bottle. I assume it keeps for several months once opened, as the dosages take several months to complete. Keep it in a cool dark place whether opened or not. Hope this helps.

Hard to answer that one. I ordered it and kept it unopened for probably 3 months with no issues but once I opened it, I used it all in one application (I had a large area to treat).

I think it is effective if it was not open, kept at relatively low temperature and not showing any thickening or discoloration. The best is to compare to a fresh product if it is available. My first one expiries in 2015. It was "open" for two years and it's texture started to change. I have purchased a new, which also has 2015 expiry date. The age of the two is almost the same but the unopened, new has smoother, thinner texture. Yes, it has an expiry date but it is hard to tell for how long it is effective. I hope this helps.

Have been using it in this twice a week a little diluted for a couple of months with no issues. Used it in the predecessor for > year which is still working.

I don't know for sure, I just know once opened, its only usable for a month. I think there might be a date on the bottom of the container if it isn't opened.

I have not experienced this even though I don't use this product like I once did. I still maintained a descent result and I'm happy with it to this day! Good luck

From what I understand, it begins to lose its potency once it's mixed as well as when it is warm. So based on that I would think that a lot of the benefits would deteriorate before the baby actually took the bottle. My suggestion would be to add it to the bottle they receive before you leave for daycare or the one they take once they get home :) I give it to my kids once a day and it seems to help but you can give them more if they need it according to the directions.

Didn't happen to me. I have been using the product for many months and am happy with it.

It becomes more liquid like when heated. Set it in a cool dry area in your house, after a day or two, it will harden again. But it really doesn't matter because depending on what you are using it for, you will most likely want it to be warmed so it's easy to apply. It's a great product, I have told everyone about it! ��
