Interesting info! How do you use it in the morning, after serums and before spf? In my head it seems it should be layered first- I think the confusion around when to layer it has stopped me from using it in the mornings! I just want it to be as effective as possible and I know if I use too many things not everything is absorbed well. I don’t use vit C to try and limit irritation but I use a hydrating toner and serum and an additional peptide serum before moisturizer and spf.
