SkinCeuticals - Pickyplans review for Discoloration Defense

This is a nice serum that is very lightweight and doesn’t leave any grease or feeling of residue on the skin. I tried a small foil sample packet and it lasted me a few days. I wasn’t expecting the dark colour of the serum, but I think it has pure ingredients. I would be interested to try a full size so I can see if it helps to lighten any dark spots.
