Storing Vitamin C in the refrigerator vs away from sunlight, which is better to avoid oxidation?

Hello skincare enthusiasts! Currently I am testing Tiam's 20% Vitamin C serum. They have mentioned to store the serum in the refrigerator so the oxidation process slows down. If I were to store the serum away from sunlight, such as in a drawer, will that also help to slow down the oxidation? Or is keeping in the refrigerator is the best way to store? Just wanted to know your ways of storing your vitamin c products 😊

Keep it in the fridge…put a foundation pump on the bottle…reduces exposure to light and oxygen

I suggest following their guide, dear. I'm using a vitamin C 🍋 serum which oxidized slightly. Here's my experience ⬇️ https://www.instagram.com/p/CT9SZZipRMf/?utm_medium=copy_link Placing the serum in the refrigerator definitely helped!

imo. it’s best to store right in the fridge. i got the 21.5 % vitamin c from wishtrend , at first I store in a dark drawer & i noticed that it’s starting to oxidise slowly even though I didn’t even open it yet so i straight away store in fridge & it’s much better then b4. to be safe , best store in fridge ☺️☺️

Fridge is the best. I use the Purito Vitamin C and most reviews says that it oxidizes fast. I store in the fridge and it lasts for 2 months.
