Hello everyone, As I learn more about the shelf life of products, I doubt the effectiveness of companies sending products made in 2019 as it is now 2021. I have taken the plunge and I decided to buy the La Mer Soft Fluid Longwear Foundation with the code A79, which means it was made in July 2019. It is almost 3 years old. Is it still good? Despite this, I also have Bare Mineral makeup with the batch code: 9205Z6. What do you think of the products made a few years ago? Thank you all!
