I've been taking a multivitamin for about three months now for general health maintenance and skin support. I found one that has many of the ingredients I was looking for that may help keep skin healthy like Vitamins A, C, E, Grape Seed Extract and DMAE. I've recently been reading that ascorbic acid may play a role in degrading/reducing hyaluronic acid levels. I know that collagen and elastin are important in the extracellular matrix but it seems that hyaluronic acid is also important in the ECM. So when I read that Vitamin C degrades HA I started to get a bit worried that the Vitamin C I thought was so good for your skin might actually instead do harm to your skin making you look older. I'm very interested to hear what others here think about this possibility. Because if it's so, we have to start looking into this more. I'm getting 250 mg of Vitamin C in the multivitamin I'm taking now.
Here's one link to some research on this topic:
