How do I know what Vitamin C product is best for wrinkles and fine lines?
What to look for in a vitamin C serum. Form: Vitamin C can appear on the ingredient label as several different names, but the one you want is L-ascorbic acid, which is the most effective. Studies comparing common vitamin C derivatives like esters and ascorbal palmitate with L-ascorbic acid didn’t show an increase in absorption.
