Do direct acids (lactic, glycolic) lose their efficiency over time once exposed to air? I’m currently cycling through a couple products and wonder if this is a bad idea if I’m trying to maximize product efficiency.

Thanks for doing this! I’ve been using your products for years and they have been amazing for my skin. I love the science behind your products and especially love your new recycling program :)
