Are there retinol serums which don’t need to refrigerate?

if a product is packaged well (opaque packaging, with an airtight pump and cap) it will last a lot longer. the main killer of retinol is oxygen and UV light, refrigerating is just an extra step. paula's choice packages their retinol products correctly.

I go through mine fast, and keep in a dark, cool cabinet, so I don't refrigerate at all

I haven't refrigerated any of my serums so far. I'd lool at the packaging instead of the percentage of active ingredients in a product

Coming to learn. I only put vitamin C in fridge. Good to know it is better to put retinol in fridge.

I've not refrigerated the retinol I'm currently using, but the packaging is similar to what @Robynrose was describing.
