I've been using Paula's Choice Vit C and like it very much. It has the ingredients that I want: L-Ascorbic Acid and Ferulic Acid.
But as with most C serums, the lifespan is approximately three months before it begins to oxidize. So I am thinking of switching to Timeless, not because I think it won't oxidize in that time frame but because it is less expensive.
So I'd appreciate any pros and cons about this particular serum -- any irritation or other problems.
TIA.
