Should you refrigerate Melano CC?

This is why I store my serums in the fridge in their original boxes. But with the Melano CC Essence's very opaque packaging, I was confident that I wouldn't have to refrigerate it. ... Most ascorbic acid serums use dropper caps but this still exposes the serum to air and light each time the bottle is opened.

How do I know when my Japanese product expires?

On most items there may be only one of the expiration dates present on the packaging. We recommend that you read and compare the name of the two different dates in kanji to the one on your food item very carefully. Be aware as well that in Japan the dates are written as year/month/day.
