There is a water based Vit C serum in a pump bottle, the kind with the screw on lid with the straw that pumps up the product (think perfume bottle), will that still maintain stability of the ingredients as opposed to the bottle where the bottom is pushed up everytime the product is dispensed?
You can think of it like this:
Open mouth contains are the worst because they expose the product to more oxygen each time you use it.
Regular pump products are better but they can let air into the package when you pump. (Otherwise a vacuum would be formed.)
Airless pumps (the kind where the bottom is pushed up) are best because they expose the product to the least air.
any idea how long u could use a pump packaged product for? Vitamin c with water (this formula in question uses other forms of C besides AA.)
