The Lacura serum gets a lot of love here, and I have totally bought into the hype, but which one is the one? I am mid-30s, not ever used a serum before, massive pores and bumpy forehead, otherwise decent if sensitive skin. I have seen Aqua-complete, Anti-ageing and Revital in the range.
(And I can't get them all to try because the Aldi near me doesn't stock any, and the person picking one up for me may not accept payment, so I don't dare to ask for several.)
