Shelf life of my discontinued HG foundation?
Planning to stock up on the now discounted original formula of EL Doublewear foundation. I go through a bottle every 10-11 months. I already have an unopened bottle that I expect to finish by summer 2027 and was thinking of buying 3 more which would last to end of 2029 (3.5 years from now).
I’ve read that foundations have a shelf life of 2-3 years. ELDW is a pretty stable foundation though. I have never had a bottle oxidize on me even when I had a long period of having opened bottles (was mixing shades to pan a bad color match).
Am I pushing it with 3 more bottles or should I just buy 2?
