Do I need to keep Retinol and Hyaluronic acid in the fridge

I always rely on the manufacturer in such questions. Sometimes vitamin C does not need to be stored in the refrigerator. Read what is written on the packaging/instructions. But I heard about hyaluronic acid that some people store it in the refrigerator so that it cools the face a little. Everyone has a different opinion😅

I always keep my retinol in the fridge, but not hyaluronic acid since it is shelf stable.

You should see what the product info says, some products say that it’s better to store them in a refrigerator but some don’t, my differin (retinol) cream says keep under 25 C it’s only about 21 C in my bathroom so I don’t refrigerate it, it is true though that sometimes your products can have a more cooling effect when they are kept at a lower temperature

It's not necessary... Probiotics are the ones that NEED to be refrigerated. I'm sure there are others as well but probios I believe are the big one

No. I would like to store them in room air.
