How to choose a Vitamin C serum

Should you avoid vitamin C serums that contain water? And is clear packaging a no-no? My dad helps clear some things up.

Vitamin C is known by many names, but you’ll commonly see it listed as “ascorbic acid.” Deciem’s The Ordinary has written a pretty serious Vitamin C skincare guide that claims that once vitamin C (in the form of ascorbic acid) hits water, it begins to oxidize (lose its effect) and change into a darker yellow/orange color.
