Ingredient Potency of Jarred Moisturizers?
Saw an interesting discussion on a review of a moisturizer on the Sephora website. A consumer quoted Paula's Choice...
"The fact that this moisturizer is packaged in a jar means the beneficial ingredients won't remain stable once it is opened. All plant extracts, vitamins, antioxidants, and other state-of-the-art ingredients break down in the presence of air, so once a jar is opened and lets the air in these important ingredients begin to deteriorate ."
What do you all think about the stability of
- plant extracts
in jarred products?
