Most people who use a vitamin C serum have seen it happen. The bottle starts out clear or pale gold, and a few weeks later it has turned a worrying shade of orange. That colour change is the active ingredient breaking down. The customer paid for potency and is now applying something far weaker, and the brand has quietly lost a little trust.<\/p>\n\n\n\n
