One fact I want to share, confirmed by dermatologists I've asked is, don't waste your $ on that face saving moisturizer if it's in a glass container! I never gave it much thought before, but won't even look at glass jars now. #1- the second you unscrew the lid, all those expensive, anti-aging ingredients disappear into the air! Sure, it looks like the better buy is to get the jar- bigger, last longer, probably a couple bucks less than that dinky tube next to it. NOPE. #2- I guarantee that jar will dry out faster, but we have to use it until empty-$$. The plastic tube, on the other hand, is sealed. Those expensive, active ingredients I spoke of will remain protected from the air right down to the last drop. Now, that little tube that appeared to be the more expensive buy just turned into one long lasting product, that you are confident is as "good" as the day you bought it. Being fresh for life means- a little is all you will need! I mean a dab! A 1oz tube has lasted longer than any glass jar I've ever purchased,and I can tell the quality's as good as the day I bought it. Next time the same product is sitting with a tube or a jar- TUBE. There's truth to, big isn't always better. Below are 3 FANTASTIC facial moisturizer's with retinol, all bought on ebay at an incredible price. Grab a tube, try 1 of these 3, and get your money's worth!
