Hi everyone. Guys I am hoping for your expert opinion on a product I just discovered a month ago and have had amazing results with. Here is the ingredient list:
Water/Eau, Glycerin, Glycolic Acid, Panthenol, Propylene Glycol, Sodium Hydroxide, Citric Acid, Butylene Glycol, Hydroxyethylcellulose, Aminomethyl Propanol, Lactic Acid, Benzyl Alcohol, Allantoin, Cellulose, Aloe Barbadensis Leaf Juice Powder, Xanthan Gum, Calendula Officinalis Flower Extract, Cellulose Gum, Zingiber Officinale (Ginger) Root Extract.
It's a daily exfoliating serum that I have been using nightly before my retin A. I can't believe how soft my skin feels, how my pores are appearing (weasel word) less clogged and reduced (another weasel word) in size. I swear I'm not getting as oily during the day either.
So what's the problem? Just as soon as I have found my holy grail I've discovered it'd being discontinued!
In a knee jerk reaction I have purchased the last 6 bottles on the shelf luckily on deep discount. At my current rate of use I expect a bottle to last 3 months. An online lot checker tells me they were manufactured October 2014 which gives me approx 14 months to use them up. I've now got 18 months worth.
Based on the ingredients above, excellent storage conditions out of heat and light - how long past the mfg recommended shelf life I can safely use this up in and do you think I should stockpile more if I happen upon them?
Please don't give me the canned repsponse as the manufacturer would - you know the one where they say they cannot guarantee the efficacy past 36 months blah blah blah.
I want to know what the science says about these ingredients please and if in fact that canned response is the best I can do I'll start shopping for a new provduct 3 or 4 bottles in to my stash.
Comments
Propylene Glycol in such high amounts can be a problem for sensitive individuals. If it's in the first third of the ingrediënt list, I would avoid it.
If you store it in a refrigerator you can definitely store it a bit longer, the stability of the product has been tested under extreme conditions. But I guess it is hard to say for how long it will stay good.
